PBX15 Series – Explosion Proof Pressurization Blowers

Control and computer rooms, offices and manufacturing facilities in dusty, corrosive or hazardous locations require both pressurization and air filtration. Positive room pressures and minimum air flows across door openings are mandated by NFPA 496 and other industrial codes. PB 15 units provide these functions automatically with one compact, pre-assembled and pretested system. Explosion proof models meet the requirements of Articles 500-503 of the National Electric Code (NEC) for Class I, Groups C and D or Class II, Groups E, F and G, Divisions 1 and 2.

A control panel in the conditioned space facilitates setting and monitoring the desired room pressure. This pressure is then automatically maintained by variable speed, low noise blowers. Only the amount of make-up air required to offset losses from building leakage and door openings is supplied. A choice of PBX 15 series models provides air flow up to 6250 cu- ft per minute at standard or high static pressures. A built-in filter housing can be fitted with a choice of special filters including filters for particulate, corrosion or odor control. Deep bed carbon filters are available with either standard or modified carbon packings.

PBX 15 series systems provide significant savings in both initial equipment and long-term operating costs. The automatic air flow control reduces the capacity requirements for both air conditioning equipment and for air filters. Gone are sluggish response, need for constant adjustments, and high maintenance of pressure controlled mechanical dampers. Options include an audible pressure loss alarm, time-controlled air purge, filter alarm, and specific gas sensors.
