3.2 Compressor room
– Protect compressed air receivers against damage through mechanical
effects (e.g. falling objects).
– Operate the compressed air receiver and its equipment from a safe location.
– Adhere to safety areas and safety clearances.
– Ensure that the compressed air receiver stands securely. It must not shift
or tilt due to external forces. This also includes the additional weight dur-
ing a pressure test!
– The compressed air receiver must not be bolted to the base.
– Ensure that the compressed air receiver is easily accessible from all sides
(for recurring tests).
– Ensure that the factory label is clearly visible.
– Ensure that compressed air receivers are adequatly protected against
corrosion.
– Only use the compressed air receiver for compressors operating with cut-
in and cut-out mode if the pressure fluctuation range amounts to
Δ p ≤ 20 %
of the maximum operating pressure.
The following applies to rooms in which compressors with oil injection cooling
are to be installed:
– For compressors with motor ratings exceeding 40 kW, ensure that the
compressor room is equipped with special fire protection.
– Install compressors with motor ratings exceeding 100 kW in a separate
fire protected room.
Requirements of fire protected compressor rooms:
– Walls, ceilings, floor and doors must be designed in fire protection class
F30 or higher.
– Flammable liquids must never be stored in the compressor room.
– The floor around the compressor must be made of non-flammable
material.
– Leaking oil must not spread out over the floor.
– No inflammable materials must be located within a radius of at least
3 metres around the compressor.
– No inflammable machine parts, such as cable ducts, may run overhead
of the compressor.
Only install compressors in workrooms if the sound pressure level of
their measuring surfaces does not exceed 85 dB(A).
