High Quality Standards
The Recirculating Paint Spray Booth is designed to meet the requirements of OSHA, NFPA-33 and HAP (Hazardous Air Pollutants).
NFPA-33 states: "A paint spray booth must provide adequate ventilation to control the concentration of flammable vapors below 25% of the lower explosive limit and it maintains the toxicity and permissible exposure limits below levels as stated in OSHA 1910.1000".
Design Performance and Benefits
This system dramatically reduces the amount of exhausted air. This is especially important if abatement is required by local authorities. In this case the air is rich in solvents and the volume sent to the abatement device is much lower. Abatement machinery is much more efficient when operating at higher concentrations of exhaust gas.
Use of energy in paint booth is a serious concern in this era. Energy use is at a minimum when using a recirculation booth. At a recirculation ratio of 80:20% energy use is reduced by a factor of five. This is especially important when the booth is temperature and humidity controlled. Not only is energy use reduced greatly, but so
is capital expense because the equipment (air handling and abatement) is also reduced in size.
