Comprag А5510 [15/92] Connection to the compressed airline

COMPRAG Screw air compressor A-Series

Choose a facility for installing the compressor with a minimum level of dust. Install the com-

pressor at least 1,5 m from walls.

If multiple compressors are installed, there should be a 1,5 m minimum distance between

each compressor.

There should be a 4 m safety distance from the area of the operated equipment connected

to the compressor.

The facility in which the compressor is installed must be tted with a combined extract-and-

put ventilation system.

The facility where the compressor is installed should be provided

with air inow equivalent to twice the compressor’s capacity.

3.4 Connection to the compressed airline

Provide the throughput capacity of the compressed-air line in accordance with the perfor-

mance of the compressor.

In order to avoid damage associated with seal failure of the compressed-air line, the com-

pressor should be connected via a exible hose.

All components of the compressed-air line must have a working pressure no less than the

compressor’s nominal pressure.

Use a pressure vessel with a capacity corresponding to the compressor’s performance and

the compressed air consumer.

3.5 Connecting to power supply

The compressor is not supplied with a power cable.

The cable size must be chosen to ensure that the maximum voltage drop not exceed 5 % of

the nominal voltage value. Cable length must not exceed 25 m. Ambient temperature in the

facility must not exceed 40°C.

The cable must be sheathed with a re retardant compound.

An isolating switch must be tted within reach of the compressor to facilitate connection

and maintenance.

The compressor must be earthed and protected against short

cir- cuits in each phase, impermissible voltage uctuation and

phase failure.

The power cable has to be fed into the compressor.
