Description The Powerex Oilless Rotary Scroll Air Compressor has advanced scroll compressor technology through the development of a completely oilless unit. The Powerex Scroll Compressor offers a dynamically balanced air end which insures vibration-free operation. The rotary design permits a continuous 100% duty cycle. No oil separation, oil ltration, or inlet valves are required on the Powerex Scroll air compressor. The Powerex oilless rotary scroll air compressor is based on the theory of scroll compression. A scroll is a free standing, intricate spiral bounded on one side by a solid, at plane or base. A scroll set, the basic compression element of a scroll compressor, is made up of two identical spirals which form right and left hand parts. One of these scroll components is indexed or phased 180° with respect to the other so the scrolls can mesh. Crescent-shaped gas pockets are formed and bounded by the spirals and the base plate of both scrolls. As the orbiting scroll is orbited around the xed scroll, the pockets formed by the meshed scrolls follow the spiral toward the center and diminish in size. The orbiting scroll is prevented from rotating during this process so the 180° phase relationship of the scrolls is maintained. The compressor’s inlet is at the outer boundary of the scrolls. The compressed gas is discharged through the outlet at the center of the xed scroll so no valves are needed.

Scroll Air Compressor Service and Maintenance DRY TYPE INLET FILTER 2500 Hours - Maintenance The inlet lter on the scroll compressor assures 99% particulate free air is admitted to the unit. Change every 2,500 hours or more often in dirty locations. 1. Use only Powerex genuine grease. Pump grease gun before feeding. This eliminates air from the grease passage of the extension adapter. Remove lter cover. Do not attempt to clean lter. This lter requires replacement and is to be replaced when contaminated. The bearings on the scroll compressor are regreaseable to allow extended compressor life....

Scroll Air Compressor Service and Maintenance Maintenance (continued)_ NOTE: Replace tip seal on SLAE03EB and SLAE05EHP at 5,000 hours when operated at 145 psig. The tip seal on the scroll compressor is self-lubricated and allows the unit to operate efficiently without oil and expensive filtration. The tip seal should be replaced every 10,000 hours of operating @ 115 psig. 1. Confirm if the tip seal set you purchased is correct for the air end you are repairing. See part number 12 on Page 7 for tip seal set and corresponding pump model number. One tip seal set contains all of the items in Figure...

Scroll Air Compressor Service and Maintenance Maintenance (continued) Repeat the same procedure for FS or Fixed Scroll tip seal set, remove both the dust seal and backup tube located on outermost side FS set. Insert new backup tube in the FS Scroll in the 6 o’ clock position (See Figure 8). Inserting tip seals NOTE: Tips seals for Fixed Scroll and Orbit Scroll have opposing seal cut angles (See NOTE and explanatory diagram below). Insert tip seal so that the lip of tip seal is on the bottom of seal groove and inner side of involute and the direction of lip faces the center of involute (curving...
