Function of the Powder Coating Booth

The booth function is characterized by the protection of the coating process from external influences, combined with keeping the area around the booth 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 as visual inspection only. Should one of the filter cartridges become damaged or develop a leak, 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 indicates 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, 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 factory:

• Blow off time = 20 msecs (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 is 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.

Start-up of the Powder Coating Booth

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 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.
