BSTAIR 15-20 Air & Nitrogen Boosters

FREE QUOTE ➝ Contact Our Product Specialists

There are times when regular pressure in not enough, this is when a booster air compressor is needed. There are many industries and processes where compressed air and nitrogen are used at higher pressures of up to 40 bar. PET blowing, laser cutting, pressure tests and abrasive cutting are among some of the widespread processes in which air or nitrogen boosters can be an integral part of the installation. The BSTAIR booster can be connected to the plant’s low-pressure network. The standard booster range has a discharge pressure of up to 40 bar, with a flow range of 0.4 m3/min to 3.6 m3/min.

How does booster technology 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 moving through the joint work of the inlet and outlet solenoid valves. The compressed air or nitrogen then enters the booster where it is further compressed up to 40 bar, in a single stage. The inlet pressure switch stops the booster when the inlet pressure exceeds the maximum allowed value or drops below the minimum allowed value. Cooling is provided by the axial fan installed on the shaft of the booster.

The booster is lubricated by the oil in the crankcase. The crankcase is vented via the oil separator and the oil breather, which allows operation with minimum oil carryover.
