A good compressor that is poorly connected delivers damp air, pressure that drops at the end of the line, and leaks that keep the machine running for nothing. A few simple rules make all the difference.
The order of components
For an installation with a screw compressor supplied on its own, the standard order is as follows:
- The compressor, installed level in a ventilated room.
- The air receiver, which stores air and smooths out demand.
- The refrigerated dryer, which removes moisture.
- The filters, which capture particles and oil.
- The workshop network, up to the workstations.
The Screw compressor 7.5 kW 4-in-1 already combines the first four components: it connects directly to the network.
Connection hoses
- Use a flexible connection between the machine and the fixed network: it absorbs vibrations.
- Respect the outlet connection diameter of the compressor, given on its technical data sheet; reducing the bore creates pressure drops.
- Choose hoses rated for the outlet pressure and temperature of the compressor.
Pressure gauges
One pressure gauge at the compressor outlet and another at the end of the network let you measure the installation's pressure drop. If the difference increases over time, look for a leak or a clogged filter.
Mistakes to avoid
- A network with no slope: give the pipes a slight slope and fit drains at the low points to remove water.
- Take-off points from underneath: draw air from the top of the pipe, so condensate is not sent to the tools.
- A room without ventilation: a compressor that draws in hot air overheats and wears out faster.
