BOOTH CABIN Robust double skinned walls, solid interlocked panel construction, powder coated finish and protected with plastic film.(removed once assembled.) 2. DOORS Page 2 of 7 Entrance Doors: Insulated, rubber gasket sealed doors with positive internal lock bar in threshold base and solid header base, Standard tri-fold Personnel Door: Equipped with toughened safety glass observation window, rubber sealed 3. LIGHTING ASSEMBLY Day light type fluorescent lights, horizontal hip light fixtures, Interior or exterior serviceable fixtures are available, extra side lights available ( sets of horizontal lights or sets of vertical lights optional) 4. BOOTH FILTRATION SYSTEM
Pre-Filtration: Cleanable pre-filters reduce contamination of ceiling filters. Ceiling Filters: European style blanket filters provides maximum air movement to evenly envelop the vehicle, and removes all overspray. Filters are held in position by steel knife-edge closures, no foam or rubber sealing. Paint Stop Filters: Five rows of 800 mm W X 7000mm L ( standard ). GRATING: Fully galvanized/stainless steel grates with base support structure. 5. HEATED AIR RECIRCULATING SYSTEM a) Indirect-fire 1.0-1.25 million BTU burner b) Indirect stainless steel heat exchanger c) Standard 2 x 5.5 kw motor driving centrifugal fans 1440 rpm-4 pole EXE rated d) Straight intake and exhaust duct and flue through workshop roof. e) Fuel - Natural Gas, L.P.G or Diesel Burners (please specify when ordering) 6. EXHAUST SYSTEM Either centrifugal or axial EXE rated fans is used for the purpose to maintain minimum air flow 0.27 M/sec.(down draught) or 0.55 M/sec. for cross draught. 7. SPRAY CYCLE/ Heated Spray Cycle 100% outside air is drawn through pre-filters, heated to preset temperature, passed through ceiling filters into cabin. 8. BAKE CYCLE Fully automated, including purge and cool-down cycle. Air intake fans draw 10% fresh air into cabin to reduce solvent concentration during bake cycle. Lights turn off automatically during bake mode. Page 3 of 7
9. ELECTRICAL AUTOMATIC CONTROL PANEL or PLC (computerized control panel ) Digital temperature controller, hour meter, bake timer, cycle selector, buzzer and indicator lights. All components are recognized, listed or certified by UL, ETL or CE Standards. Main points of Panda design and manufacturing reference in relation to Australian, New Zealand Spray coating Standard(4114). 1. All components used in construction must be non-combustible and Panda has independently had the wall panels tested and certified. 2. All booths shall have enough exit doors so that the painter has to travel no more than 6 metres to exit the booth from which he is required to work in. 3. If shelves are fitted they must be of perforated sheet metal or similar to allow air flow through them. 4. Equipotential bonding must be in accordance with AS 2381.1. This is basically ensuring that the booth must be properly earthed to avoid the possibility of a spark occurring. 5. Ductwork - must be manufactured from sheet metal or other non combustible material. Intake ducts must have mesh screens approximately 12mm to prevent things being drawn in. There must be a separate intake and exhaust duct with the intake duct being able to take air from outside of factory. The exhaust duct must discharge vertically to a point 3m above the roof. There must be a minimum of 3 m distance between the inlet and exhaust duct. 6. All windows in lights and doors must be mounted in secure frames (not rubber) and be manufactured to AS 2208. All glass is to be capable of passing the impact and thermal shock tests as detailed in AS 2380.1. All Panda light and window glass panels have been certified to AS 2208. 7. All emergency exits must be conspicuously marked "Emergency Exit" in accordance with AS 1319. All doors must open outwards and be non locking. 8. Any electrical equipment brought into the booth and their associated power connection and Page 4 of 7
wiring must be suitable for a class 1, zone 1 area. 9. Light fittings which have their tubes access from inside of the booth must be protected and approved to be protected by an explosion protection technique permitted by AS 2381.1 for class 1, zone 1 areas. Basically this means lights must be pressurised or similar. Also any system must be approved before it can be installed. The supplier/manufacturer must show a certificate of compliance or similar by an authorised testing laboratory to ensure the lights are safe and legal. 10. The downdraught booth must have a minimum air flow of 0.3 metres per second in the booth. This is measured when the booth is running in the spray cycle and empty. 11. The booth must have a monitoring system to monitor the ventilation of the booth. During spray cycle, the minimum airflow shall keep the concentration of flammable vapour in air six time lower than that as specified in AS 1735 as well as provide a minimum velocity in the booth of 0.3 m/s downdraught or 0.5 m/s cross or end draught. This system must prove supply air and exhaust air. The exhaust air monitoring is required for dilution safety and any device used to monitor the exhaust air of a spray booth, must be suitable for a class 1 zone 1 area. All flow sensing devices must self check or prove no air flow prior to allowing the booth to start. 12. The booth must have a pre purge cycle fitted. During pre purge the air flow monitoring devices once activated start a timer which is set for approximately 1 minute minimum, which should be 5 cabin air changes on a standard size car booth. During the pre purge time, the air line block valve is not energised so spraying is not possible and the heating system is also not energised until the cycle time expires, at any stage should we lose one or all of the flow sensing switches the time is reset and once the flow is re-established it is re-energised. 14 The booth also must be fitted with a post purge cycle timer which is activated when the operator finishes spraying. The cycle runs for 5 minutes and during that time the air line block valve is disabled to prevent spraying. The purpose of the post purge cycle is to allow the ventilation system to remove residual solvents from the painted car prior to the booth stopping. 15 The heating system must be designed and installed to AG501, AG601 and AS1375 requirements. The heating system can be either direct or indirect fired, providing there is 2 metres between the flame tip and air entry point to the plenum. 16. The booth must have a compliance plate stating design criteria such as gas rates, fan sizes, safety device setting as well as the solvents that the booth is designed to be used for. Booth Specification. The Panda series spray booth is a full downdraft low bake oven to satisfy the quality refinishing needs of wet spray painting application workshops. Providing a high level of safety and optimum performance we supply a wide variety of models, manufactured using quality componentry and materials. At present, more than 110 paint, panel beating, aviation, marine and various industrial workshops around Australia and New Zealand are using Panda Spray Booth Bake Ovens, Preparatory Page 5 of 7
Bays and Paint Mix/Tint Rooms. The Panda Spray Booth Bake Oven have upgraded the semi & full downdraft principle by filtering incoming air through its pre filtered and full filtered ceiling. The air is drawn over the vehicle, through the floor grating, and then filtered and exhausted via the paint stop filter and M type exhaust filter. Active carbon air filters can also be installed (optional). These specially designed booths eliminate air swirl, providing softer, more even air movement, that eliminates any over spray more efficiently and prevents paint finish impurities/debris, therefore providing a factory finish.
