5.2.5 Combination Air Filter
The intake suction air filter designed for the compressor is a dry air filter with an integrated cyclonic pre-cleaner. This filter is
particularly suitable for use with intake air with a high dust content.
•
The filter must be supported separately and mounted with two mount fittings.
•
The filter must not be fitted vertically.
•
The dust discharge valve of the intake filter must point downwards.
•
The intake filter must be sufficiently protected from water splashes, rain, exhaust gases, and engine heat.
5.3 Noise Suppression (Low Noise Installation)
The noise level of the RFL 102 is far below the value permitted for commercial vehicles. To preserve these values when the
machine is installed, the low noise installation is necessary.
Air noise suppression by noise suppressing oil separator
The combined silencer and oil separator suppresses the exhaust noise of the compressor/vacuum pump, and reduces oil
emissions.
The silencer is installed in the exhaust pipe.
The noise suppressing oil separator must be acceptable for the maximum possible operating pressure (e.g. 2 bar
pressure if the machine is used as a compressor).
The de-oiling element is connected by 2 or 3 oil draining pipes to a ventilated collecting tank with a capacity of at least 10 litres.
The ventilation diameter should be at least 1”.
