Armstrong Booster Air Compressor — BC Series
Simple · Convenient · Economy — up to 4.5% energy saving
The Armstrong BC series booster takes low-pressure compressed air from an existing screw compressor and boosts it up to 4.0 MPa, removing the need for a dedicated high-pressure machine. It is air-cooled, multi-stage, and base-plate mounted for continuous industrial duty.
Features : Advantages
- Precision valve pilot for smooth, controlled boost staging
- Automatic load / unload solenoid valve to cut standby power draw
- Built-in air-cooled aftercooler lowers discharge temperature
- Inter-stage and discharge safety valves protect against overpressure
- Air-cooled, multi-stage, base-plate mounted design
- Discharge pressure available up to 4.0 MPa (400 bar)
 Valve Pilot Regulates cylinder loading for controlled boost staging |
 Solenoid Valve Automatic load/unload control, reduces standby power draw |
