2 to 50 ton Air Conditioner, Pressurization and Optional Deep Bed Filter Module
PB 20 Series combines air conditioning, pressurization, and make-up air filtration on one skid. Units offer convenient and economic means for achieving compliance with NFPA 496 and similar industrial codes. A quiet, variable speed blower automatically maintains the preset building pressure. Only the make-up air required to offset building leakage and losses from door openings is supplied. Gone are sluggish response, constant need for adjustments, and the high maintenance associated with barometric dampers. The units are fully instrumented with thermostat, pressure selector and display, and Start/Stop controls. Deep bed gas phase and high dirt loading filters are optional. Dual (redundant) blowers and air conditioning with automatic switchover controls are optional.
