Applications PA I N T S P R AY Automotive body shops utilize atomized paint to spray vehicles. Workers exposed to airborne paint emissions benefit from BAP Breathing Air Purifiers. PR OTE CTIV E COAT I N G S Manufacturers utilize compressed air to apply protective coatings. Airborne compounds will not adversely affect workers when respiratory air is supplied with BAP Breathing Air Purifiers. C O N F I N E D S PAC E S The quality of breathing is critical in confined space industries. Mining, vats, tanks, boilers, ships’ hulls, and grain storage facilities are environments with stale,...

SIX STAGE FILTRATION Stage 1 General purpose filter removes solid and liquid contaminants down to 1.0 micron Stage 2 High efficiency oil removal filter captures liquid aerosols and sub-micronic particles down 0.01 micron Stage 3 Pressure-swing regenerative desiccant dryer removes water vapor to ensure the effectiveness of the catalyst bed Stage 4 Dried air travels through a catalytic converter reducing CO concentrations by converting CO to CO2 Stage 5 Particulate removal filter collects contaminants 1.0 micron and larger from the purified air stream Stage 6 Activated carbon filter removes...

OPTIMIZING CAPACITY Breathing air produced by a Breathing Air Purifier system can supply various levels of use. To select a BAP Series purifier, first determine the air pressure at the purifier inlet and the maximum breathing air flow required at a given time. The chart below illustrates an example of BAP Series estimated capacities based on 6-15 scfm (10-25 m3/h) per hood, helmet or suits as calculated in the sizing table. * Contact hood manufacturer for actual capacity before sizing purifier. MODEL SPECIFICATIONS IN/OUT CONNECTIONS 1 Flow capacity rated at CAGI conditions: 100 psig (7.0...

CAPACITY CORRECTION FACTORS To adjust BAP capacity for conditions other than rated, use the correction factors (multipliers) for inlet air temperature and pressure shown below. Example: What is the capacity of a 205 scfm (348 nm3/h) model when the compressed air at the inlet is 130 psig (9 bar) and 110°F (43°C)? Answer: 205 scfm (348 nm3/h) (rated flow from Product Specifications Table) x 1.08 (correction factor for inlet air temperature and pressure) = 221 scfm (375 nm3/h)
