Powder Coating Booth Characteristics

These booths are made of several different materials; steel, (painted or stainless), polypropylene, or thin polyethylene. Powder booths are sized by two airflow requirements. The first requirement is containment air.

In order to collect the over-sprayed powder particles, the powder booth is designed to provide 110-120 lineal feet per minute (fpm) airflow across all the openings A properly designed booth will have laminar airflow throughout the cabin without interrupting the powder coating process.

The second design criteria for airflow requirements are based on safety. Each powder is rated with a lower explosion limit (LEL) measured in oz/ft. The powder booth must be designed with enough safety ventilation and airflow not to exceed 50% of the LEL limit.

This powder concentration level is determined by the number of guns and nominal powder output per gun. Every type of booth designed for powder applications is designed with a recovery system. The recovery system is used for two main reasons:

1- to provide the necessary containment and safe air.
2- to recover the oversprayed powder.

Most systems sold in the U.S. have two filter sections. The primary filter is used to separate the oversprayed powder from the air from reclaim. The secondary or final filter to keep the working environment free of powder particles.

There are three main types of recovery systems available in the market today:

• Conventional
• Filter Belt
• Cartridge

The newly updated range of Cartridge Style Powder Paint Booth with Filters offers an excellent and compact alternative to more traditional Powder Coating Booths which often require separate Cyclone and Filter Modules.

There is an electrical board, to control the blow-off valves to clean the filters and lights inside for the operator to see and check the painting quality

Powder paint booth filters:

Powder paint booth filters are essential components of powder coating systems, capturing overspray and preventing the release of harmful airborne particles into the environment. These filters play a crucial role in maintaining air quality, worker safety, and environmental compliance.

Types of filtration systems:

Powder paint booth filtration systems can be categorized into two main types: dry filters and wet filters.

• Dry filters: Dry filters are the most common type of powder paint booth filter. They utilize a porous material, such as cellulose or synthetic fibers, to trap overspray particles. Dry filters offer high filtration efficiency and can be easily replaced when clogged.
• Wet filters: Wet filters use a liquid medium, typically water, to capture overspray particles. As the air passes through the wet filter, the overspray particles adhere to the liquid droplets and are then removed from the system. Wet filters are often used in conjunction with dry filters to achieve even higher filtration efficiency.

Cartridge filters:

Cartridge filters are cylindrical filters housed in a metal or plastic casing. They offer high filtration efficiency and are relatively easy to replace. Cartridge filters are commonly used in both dry and wet filtration systems.

Bag filters:

Bag filters consist of large bags made of porous material, such as fabric or mesh. They provide a large filtration area and are suitable for high-volume applications. Bag filters are commonly used in dry filtration systems.

Pleated filters:

Pleated filters have a folded or corrugated design, increasing their surface area and filtration efficiency. They are particularly effective in capturing fine particles and are often used as final filters in powder paint booth filtration systems.

Filtration efficiency:

Filtration efficiency refers to the ability of a filter to capture airborne particles. It is typically expressed as a percentage, with higher values indicating better filtration. The MERV rating is a common measure of filtration efficiency for powder paint booth filters.

MERV rating:

The Minimum Efficiency Reporting Value (MERV) rating is a standardized measure of a filter’s ability to capture airborne particles. MERV ratings range from 1 to 16, with higher numbers indicating better filtration. Powder paint booth filters typically have a MERV rating of 8 or higher.

Filter life:

The filter life depends on various factors, including the type of filter, the amount of overspray, and the frequency of booth cleaning. Cartridge filters typically have a longer lifespan than bag filters, while pleated filters may require more frequent replacement due to their finer filtration capabilities.

Important Notice: Powder paint manufacturers supply powder in particle size whereby 90% of the particles are in a size range of 200 microns. Some particles however will inevitably be much smaller. The particle size of fewer than 5 microns will migrate through almost any filter.

Operating Instructions for Cartridge Filter Spray Booths
A clean air supply rated at a minimum of 6 bars is required.
The air supply must be filtered but not lubricated as unfiltered air could lead to fragments of dirt and debris being delivered to the diaphragm valves.

This may lead to the rubber diaphragm being perforated or the valve sticking open. Both of these faults will result in a constant stream of air passing through the filter.

• Air quality regulations:

Powder paint booths are subject to various air quality regulations aimed at minimizing the emission of harmful pollutants into the atmosphere. These regulations may set limits on the concentration of particulate matter (PM), volatile organic compounds (VOCs), and other hazardous substances in the air discharged from the booth.

Powder Paint Booth with Filters

The factory timing calibration is set at 0.2 of the second pulse duration and an interval time of 15 seconds between each filter pulse. Under heavy and prolonged use it may be necessary to modify these parameters, this decision is usually determined if the efficiency of the booth begins to diminish and re-programming by Siemens P.L.C. must be done only after consultation with EMS Powder Coating Machinery.

Under normal working conditions, the cylinder cartridge filters have a minimum 1-year life span, replacement filters are kept in stock at EMS Powder Coating Machinery and replacement is facilitated by a 12 mm nut on the underside of each filter.

The filter should be blown with a hand air gun once each week with care taken to clean the top of the filters, an area the automatic cleaning seems to miss. The optimum pressure required by the self-cleaning mechanism is 60 – 90 P.S.I., however, this may be lowered to a minimum of 30 P.S.I. if notice restraint is a factor.

The pulsing will be noticeably quieter at this level, but the cleaning is not as comprehensive. To assist in cleaning in this situation it is advisable to run the machine at a higher pressure, say 90 P.S.I., for a period of 15 minutes at a convenient time. If wet paint is used the life of the cartridge filters will be reduced. Only spray within the confines of the booth. Check the sealing of the filters on a regular basis.

If the powder is escaping through the booth, the cartridge filters are not sealing correctly. Due to having to use high-pressure centrifugal fans to obtain the necessary airflow of 0.7m per second per 1m, the noise level determines that ear defenders are required.

The spray booths manufactured by EMS Powder Coating Machinery are tested in airflow in the following ways: A hand-held anemometer is used to take readings at a distance of 400mm from the face of the booth and at intervals of 300mm longitudinally. The combined total is then divided by the number of readings. The suction force equals an average of 0.7 per second or above.

Important Notes:

• The anemometer readings will vary over the face of the booth.
• The performance will drop when the filters become resistive.
• Due to the high airflow and the high pressure required necessitating centrifugal fans with forwarding curved impellers, the resultant noise level will mean that ear defenders are required.
• It is strongly advised that our patented automatic switching device is used. Tests in production indicate that over 60% of the time suction is not required, our switching device switches off the fans when the gun is in the holster, thus saving operating costs.

A Small powder coating booth with recovery are cost-effective finishing environment for small-batch powder applications and powder coating systems.

Featuring a primary and redundant filtration system, EMS Powder Coating Equipment’s powder coating booths capture high volumes of powder overspray with even small powder sizes for powder sprays that go to waste. This is a big plus in comparison to booths for wet paint. Batch powder coating booths are ideal, especially for small parts such as alloy wheels

The open-front design saves floor space and allows for easy transportation in and out of the booth.

The function of the Powder Paint Booth with Filters

The booth function is characterized by the protection of the coating process from external influences, combined with keeping the area around the booth is clean. The booth function is based on a powerful exhaust air system, which aspirates air from the booth interior through filter cartridges. The resulting negative pressure produces an airflow from the outside of the booth to the inside, thus preventing powder from escaping into the environment. In order to have a full understanding of the booth operation, the booth functions are individually described in the following sections.

Exhaust Air System of the Powder Coating Booth

The exhaust fan of the exhaust system is located in the fan housing above the filter cartridges. It sucks air from the booth interior through the filter cartridges and returns the clean air through the filter pads to the environment. The filter pads in the fan housing are intended for visual inspection only. Should one of the filter cartridges become damaged or develop a leak, the powder will be deposited on this filter stage.

The efficiency of the exhaust system depends on how severely the filter cartridge is clogged. For this reason, the suction efficiency is determined and indicated by measuring the differential pressure between the clean air side and the booth environment (pressure monitoring). A pressure rise means an increasing clogging of the filter cartridges.

Filter Cleaning

Each filter cartridge is equipped with a cleaning device and can be cleaned while the booth is in operation. The cleaning procedure is activated manually by the relevant switch on the control cabinet.

The cartridges are cleaned by compressed air impulses and injected by pressure pipes inside the cartridges. The powder drops onto the booth floor, from where it arrives into the powder trolley or the powder collector.

The filter cleaning air is supplied from the pressure tank in the exhaust air unit and must amount 5 bar (recommended), and not exceed 6 bar. The cleaning process and consequently the blow-off duration per filter cartridge and the pause time, before the next cartridge is blown off, are controlled by an electronic control unit. The blow-off time for the cleaning impulse must amount to 10-30 ms and is preset by the factory:

• Blow-off time = 20 milisecs (factory setting)
• Pause time = 10 s (factory setting)

Powder Circuit

A powder trolley is a prerequisite for working with a closed powder circuit. In the closed powder circuit, the gun is connected to the powder trolley. The powder is fed from the powder trolley via the gun to the workpiece.

The over-sprayed powder drops to the booth floor or is retained by the
filter cartridges, from where it also drops down inside the booth when the filters are blown off. The powder is scraped manually into the powder trolley, where it can be reused for coating operation.

Powder Trolley

The powder trolley is installed at the rear of the booth, under the booth floor. The powder trolley can be rolled out and pressed against the booth in its working position. Herein, the powder is fluidized, then sucked up by the injector, and fed to the gun. The powder which has dropped to the booth floor is fed back into the powder trolley through a vibrating sieve. Thereby, contamination in the powder is eliminated. The sieve can be switched on with the button when required.

Filling the powder trolley

The following section describes how the empty powder trolley is to be filled. The powder trolley can only be filled manually. Before filling the trolley, it may be necessary to carry out a coarse cleaning of the booth.

In order to eliminate a powder contamination, fresh powder should not be filled directly into the trolley; the following procedure is recommended:

1. Switch on the booth with the button
2. Switch off the electrostatic control units
3. Switch on the sieve with the button
4. Evenly distribute portions of fresh powder directly over the sieve. The powder is passed through the sieve and freed from any contamination
5. Repeat this procedure until the required amount of powder is in the container
6. Check the powder level through the control flap of the
   powder container
7. The filling capacity by empty powder trolley is approx. 15 kg plastic powder (average value).

Procedure

1. Release the compressed air circuit (input pressure must amount to at least 6 bar)
2. Switch on the booth (switch on the main switch, and press the button), see also chapter “Switching on the booth
3. Adjust the operating parameters on the pneumatics cabinet: Sieve pressure reducing valve (4): approx. 2-3 bar, depending on the powder type Fluidizing pressure reducing valve (3): approx. 0,5-1,5 bar, depending on the powder, the powder should lightly “boil” (check this through the inspection flap of the powder container)
4. Check the fluidization and regulate, if necessary. The adjustment of the required fluidization air pressure depends on the powder type, the air humidity and the ambient temperature. For this reason, only an arbitrary fluidization setting is possible and should be readjusted, according to previous experience for the powder type being used

Maintenance

Daily Maintenance Works

• Blow off the hose with compressed air
• Clean the outside of the gun and check for wearing parts
• Coarse cleaning of the booth (see therefore chapter “Coarse booth cleaning”)
• Check the vibration sieve in the powder trolley and remove any contamination
• Clean the filter cartridges (see therefore chapter “Filter cleaning”)

Weekly

• Clean the filter cartridges and check for visible damages, if necessary, replace (see chapter “Replacing the filter cartridges“)
• Check the filter pads on the exhaust air exits of the fan housing, a large powder deposit indicates a defective filter cartridge, replace the defective filter cartridge or the complete filter set (see chapter “Replacing the filter cartridges“)
• Clean completely the booth (no wet cleaning!)
• ATTENTION:
• A booth cleaning should not take place immediately after the powder trolley have been filled with fresh powder; danger of overflow!
• Empty the powder trolley
• Check the oil/water separator and empty, if necessary (if oil is present, the customer should check the air compressor)

Biannually

• Inspect the exhaust fan (motor and blade wheel) for dust and powder deposits. A service port is provided on 4-kW motors.

Replacing the Filter Cartridges

A filter cleaning operation must take place before every filter cartridge
replacement:

• Start up the booth
• Press the switch (filter cleaning) and wait until all filter cartridges have been blown off, then press the switch again to switch off the cleaning (see therefore chapter “Filter cleaning”)
• Switch off the booth

Procedure for Replacing the Filter Cartridges

• Remove the shield (Classic Standard 4 and Open only)
• Loosen the fixing screws a couple of turns with the correct size spanner. Do not unscrew completely!
• Hold the filter cartridge in both hands, turn slightly and hang it out from the holding screws
• Place the filter cartridge away
• Clean all parts, especially the seating surfaces

Assembly:

• Unpack the new filter cartridge
• Hang the filter cartridge onto the fixing screws and turn to the
  stop
• Tighten the fixing screws evenly, so that the sealing ring
  touches all round evenly and the filter cartridge hangs
  vertically

Our cartridge spray booth is designed to capture excess powder during application. It is the culmination of many years of experience in designing and building machinery for powder coaters.

To comply with recent changes in legislation we have now upgraded our cartridge booth by fitting two centrifugal fans of 5.5kw capacity and six cartridge filters.

Our Powder Coating Booth Features

• 100% filtration means that the air filtration system does not require ducting to the outside. This makes installation easier and also increases overall energy efficiency, as you don’t lose heated factory air.
• Unlike water back booths, there is no ongoing expense of sludge removal.
• High quality in every sort of finishing systems
• The filtered powder is collected in a tray, making disposal easy.
• Centrifugal fans are used to remove contaminated air, and are more powerful than axial fans.
• Large, quick-acting air valves direct a blast of air into each filter at intervals of 30 seconds to keep them working efficiently.
• Option of auto-switch – when the powder gun is taken from the holster the fan automatically switches on, replace and it goes off. This device can substantially reduce energy consumption.
• Completely manufactured at our UK workshop. Our machinery is manufactured to a high quality and is built to last.
• Flat packed for easy transportation and installation.
• Full compliance with HSE guidelines.
• CE mark.
• Fully guaranteed.
• Service contracts are available.

Auto-Switch

Infra-red detection device built into the holster for the powder gun. The auto-switch shuts off the booth when the gun is housed and switches it on when the gun is taken out of the holster. This device makes big savings in power and also reduces the noise coming from your spraying area.

Lighting

Lights are not included in the standard price – price on the application.

Track System

A track system is easily fitted to link your spray booth to one of our ovens. Depending on your individual circumstances, these may be either single runners or flight bars and we can supply them in a range of lengths.

Price on application

Silencers

Silencers reduce the noise from our spray booths by 10 decibels. A 2-meter booth requires 1 silencer, a 3-meter booth requires 2 silencers.

Please note that this spray booth requires compressed air to function correctly.

We can arrange for our spray booths to be shipped worldwide; we charge for shipping at cost.
