bstAIR 40 - Air & Nitrogen booster

From PET bottle blowing and laser cutting to plastics forming and pressure testing, there are many industrial processes that require high-pressure compressed air or nitrogen. And that’s exactly what the bstAIR 40 delivers.

It can supply quality air with a pressure of up to 40 bar more efficiently than a high-pressure compressor. In addition, the bstAIR 40 is extremely reliable, flexible, and easy to operate.

How does the bstAIR 40 work?

Air or nitrogen is compressed in a single-stage pump using the standard operating cycle of a piston compressor. Compression starts at a low pressure with the air or gas moving through the inlet solenoid valves. It then enters the first and only stage of the booster, where it is further compressed to reach a maximum working pressure of 40 bar. To protect the unit, the inlet pressure sensor stops the booster when the inlet pressure exceeds the maximum allowed value or drops below the minimum value. Cooling is provided by the axial fan installed on the shaft of the booster. The bstAIR 40 has a splash lubrication system. The crankcase is vented via the oil separator and the oil breather to limit oil consumption.
