Description

The bench  PCB300 allows to study the operating principle of a screw air compressor.

The ambient air is drawn at the level of the filter where a diaphragm is found allowing measuring the incoming air flow by means of a manometer column.

The air passes successively through two air water exchangers connected to the water networks of the institution.

At the output of exchanger, the air return in the tank then at the level of a pressure reducer connected three outlet diaphragms to measure the outlet flow rate using a differential pressure sensor. The robust design of this device makes it suitable for use in schools.
The equipment is set up on an Anodized aluminium frame on casters wheels. This gives it great strength and a flexibility of integration into your premises. The manufacture of this equipment complies with the European standard for machinery manufacturing.
