The lubricant used in chemically active applications to lubricate the timing gears and support bearings should be an inert synthetic lubricant, such as chlorofluorocarbon. Faulty Inlet Valve. Compressor Will Not Build Pressure. Sollant 11kw rotary screw air compressor’s pressure is adjustable, We can set the pressure according to your requirements(7-12bar), It’s motor safety grade reached IP23/55 and. That pump pulls in free air from the atmosphere and is supposed to drive it into the tank, and that increases pressure in … Lubricant-injected rotary screw compressors provide continuous flow without the pressure pulsations typically associated with reciprocating compressors. Unlike motor oil, air compressor oil does not contain detergent, and typically has lower amounts of carbon, sulphur and other contaminants that can cause build-up. Shut the drain valve at the bottom of the tank if it's open. Change ), You are commenting using your Twitter account. Check supply power. Ordered gasket kit and replaced all gaskets and reassembled.
