Description

The PCB050 bench allows to study the operating principle of a two-stage air compressor.

The ambient air is drawn at the level of a filter is found allowing to measure of pressure and temperature.

The air passes successively through two air-water exchangers (1st stage and 2nd stage) connected to the water network of the institution.

At the output of second exchanger, the air returns in the tank then at the level of a pressure reducer connected to an output of air flowmeter. The robust design of this equipment makes it suitable for use in schools.

Anodized aluminum structure on multidirectional wheels with brakes gives it a very robust as well as a high flexible integration into your premises.The manufacturing of this equipment meets European machine directive
