PBX 15 Series Controlled Pressure Blowers

Airflow up to 6,250 CFM, with Optional Deep Bed Filter Module

Scientific Systems LLC's PBX 15 Series controlled pressure blowers provide pressurization and air filtration for buildings in hazardous, dusty, or corrosive locations. The PBX 15 Series offers safe, ergonomic compliance with ISA, NFPA, API, and related industrial codes. Explosion proof models are designed for use with NEC Class I (Groups C, and D) and Class II (Groups F, and G) codes under Division 1 and 2.

Features of the PBX 15 Series

Each unit includes automatic building pressure control, air filtration, and heating in one pre-assembled module that is skid mounted and pre-tested for time-saving installation and start-up. PBX Series 15 blowers are fully automatic; a speed modulated blower maintains a preset pressure and eliminates issues with damper systems. Blower capacities reach 6,250 CFM, and pressure is adjustable from 0.025 inch wc. An optional, applications-engineered filter housing accepts a wide range of particulate, carbon, multi-mixture, and most competitive filter modules. See other optional features and accessories listed in our features section below.

Units can be installed indoors or outdoors, on rooftops or at ground level and allow component isolation for maintenance purposes. All models are computer selected, fully instrumented, and factory tested. The result is clean, precisely pressure-controlled air.
