GENERAL
The Powerex oil-less tank mounted system is designed to provide clean, dry air for industrial applications where the quality of the compressed air is critical (dryer option is required for the dry air application).

AIR COMPRESSOR SYSTEM
The package shall include one or two oil-less reciprocating air compressor/s and associated equipment, one ASME air receiver, and one optional magnetic starter/alternating control panel.  The only field connections required will be system discharge, power connection at the control panel and dryer, and condensate drain connection.  All interconnecting piping and wiring shall be included and operationally tested prior to shipment.  A desiccant or refrigerant air dryer system is optional.

OILLESS COMPRESSOR PUMP
Each compressor shall be of the following design: belt driven, reciprocating type, single-stage (1-3 HP), or two-stage (5-15HP), single acting, air cooled, oil-less construction with absolutely no oil needed for operation.  Pistons shall be manufactured of heat rejecting Composite Resin with PTFE rings.  Aluminum pistons shall not be used.  Compressor design shall also include stainless steel valves with PTFE coated aluminum die-cast valve plates, precision bore die-cast anodized aluminum cylinders, anodized inter-stage intercooler(s), ductile iron crankshaft with counterweight and oversized sealed ball bearings, and single piece connecting rods with sealed needle bearings.  Compressors shall have a “Dual Cooling System” which includes a radial flow fan and flywheel fan, which are driven by the pump crankshaft.  Each compressor shall be equipped with a check valve.  Each compressor unit shall be capable of up to 145 psig continuous-duty operation.

MOTORS
Each compressor shall be belt driven by a 1750 RPM, ODP NEMA construction motor.  Motors operating at speeds higher than 1750 RPM shall not be acceptable.  OSHA approved belt guards shall be provided.  Motor shall not operate in the service factor.

AIR RECEIVER
The system shall include an ASME rated air receiver, rated for 200 PSI MAWP.  The tank shall be equipped with a pressure gauge, safety relief valve, discharge shut-off valve, and manual tank drain.

SIMPLEX – The system shall include a UL listed magnetic starter in a NEMA 1 enclosure with 3-leg overload protection, hour meter, and overload reset button.  A NEMA 1 pressure switch shall control the start/stop operation of the compressor and shall operate in the range of 90-120 psig.
