Brand-specific oil separator filter to filter and reduce the oil mist content in the exhaust side. The filters are typically cylindrical, and filter the air flow in the pump. The Rietschle oil separator filter (exhaust filter) has been further developed, therefore no extra fastener is required. At some separator types the separator is connected in a separate plastic mounting that may need to be changed regularly. There is an oil drain under the frame (at six o’clock). Alternative Rietschle oil separator filter for pump types V-VGA, V-VGC, V-VGD, V-VCB, V-VCA, V-VCE, V-VC.
