Air system The following slides explain how the regulating system of the XA(H)S 146-186 works. They will give you an overview of the different parts and their function.

Air filter centrifugal dust separation paper filter element Filtration of the inlet air in 3 stages : centrifugal dust separation paper filter element safety cartridge Vacuum indicator gives an indication when the pressure drop over the filter element is too high  filter element needs to be replaced

REGULATING SYSTEM REG VALVE Spring loaded Adjusting receiver pressure by changing spring tension to pressure gauge and loading valve to speed regulator to unloading valve Regulating pressure: Receiver pressure In order to regulate the pressure inside the reciever tank of our compressor, the air intake and the engine speed have to be controlled. This is done pneumatically. For that reason, we need regulating pressure. The regulating valve reduces the pressure inside the tank, thus providing the regulating pressure. This regulating pressure is then supplied to the unloader valve and the speed regulator or RPS. The air receiver pressure can be set to another value by adjusting the spring tension of the regulating valve. This is done by turning the handle on top the valve. Increasing the spring tension, by turning in, will increase the regulating pressure and consequently the pressure inside the vessel. Turning out will decrease the pressure.

Unloading valve Open position at load condition => Air consumption Opens and closes the air inlet to the compressor element. Open position at load condition => Air consumption Closed position at no load condition => No air consumption. Control of the valve by regulating pressure.

Unloading Valve or Air System Inlet Valve Air intake pneumatically regulated by regulating air at back of piston Closes by regulating air Opens by vacuum from element inlet Some air taken in during unload through calibrated hole in piston Unloading valve includes blow down valve Unloading valve service kit – 2911 0169 00

Oil System Air receiver Oil cooler Oil filter/TBV Compressor element Oil separator Scavenge line Oil stop valve The following slides explain how the regulating system of the XA(H)S 146-186 works. They will give you an overview of the different parts and their function.

Oil separator Scavenge line Separator element Centrifugal separation Oil Separator filter element should be replaced Every 1,000 hours or yearly. Centrifugal separation Oil Air/Oil

Oil Separator Separator Element Service Kit – 2911 0169 00 Classic Reasons For Oil Carryover Over filled receiver Plugged scavenge line Wrong type of oil (no anti foam agent) Shut down with air outlet valves open Scavenge tube installed improperly Separator Element Service Kit – 2911 0169 00

Checking compressor oil level With compressor turned off and level, check the oil level in the receiver tank The pointer of the oil level gauge should read at the top edge of the green range Be sure to relieve all air pressure by opening an air outlet valve before removing the oil filler plug

Output pressure adjustment Be careful not to touch hot parts when the machine doors are open Loosen the lock nut on the regulating valve Release regulating valve With outlet valves closed, adjust the regulating valve until the pressure is 29 PSI above the nominal pressure desired Lock the regulating valve by tightening the lock nut
