Single-stage Aerzen Screw Compressor units are excellently suited for the dry and clean compression of air and neutral gases.

Installation

The packages are delivered completely assembled, allowing their prompt and trouble-free installation. Installation procedures on site are limited to the connection of power supply and plant piping resp. filling-up of oil. The standard package designed for pressure mode operation sucks in ambient atmospheric air through a filter. In vacuum mode and nitrogen operation, the intake filter is substituted by a suction silencer of pipe connection. An additional expansion joint with tie-rods ensures stress-free intake connection to plant piping. The standard package is designed to accept motors that have IP 55 type protection.
In the case of packages equipped with an acoustic hood, the electrical wiring as well as the motor contactor and pushbuttons can be installed in the standard instrument panel (only applies for machines with a gearbox).
