In your response be sure to identify your business size, and provide the manufacturer of your proposed product, as well as specifications detailing compliance with the below. Specifications A. Portable Rotary Compressor Package 1. Air compressor shall be a single stage, oil-flooded, air-cooled, rotary screw compressor completely pre-piped, pre-wired, and ready for operation. 2. Portable compressor shall be manufacutured under strict ISO 9001 quality standards. 3. Compressor shall be tested as a completely assembled unit. 4. Capacity shall be 950 cfm free air delivery at a discharge pressure of 100 psig. Compressor shall be capable of continuous full flow operation 24 hr/day at rated capacity and pressure. 5. Engine shall be a water-cooled, 4-cycle industrial duty engine. Control system voltage shall be 24 VDC. 6. Standard compressor package shall be suitable for use in a 35 degree F to 122 degree F ambient temperature range. B. Airend 1. Rotors?airend rotors shall have a Sigma profile. Rotors shall be precision machined from cast iron. All cast parts shall be 100% inspected for compliance with design tolerances. 2. Casing?airend casing shall be cast iron construction. 3. Bearings?airend rotors shall be supported on both ends by cylindrical roller bearings to carry radial loads. Angular contact ball bearings shall be installed on the discharge end of each rotor to carry thrust loads with minimal friction. C. Engine 1. Engine shall be water-cooled, 4-cycle, 6-cylinder industrial duty turbo charged diesel engine. 2. Engine shall be rated 236 hp @ 1700 rpm. 3. Power consumption or airend and fan unit shall be 209.2 hp. 4. Engine off load speed shall be 1200 rpm. 5. Engine shall have heavy-duty 24 VDC starter. 6. Fuel consumption shall be 10.7 gal/hr under fully load and 5.7 gal/hr at off load. 7. Fuel tank capacity shall be 145.6 gal. 8. Operating hours at fully load shall be 13.6 hr. 9. Oil capacity shall be 3.83 gal. 10. Engine shall have an oil pressure switch with shutdown function. D. Starter 1. Unit shall have an electric 24 VDC starter. 2. Starter shall be heavy-duty design, mounted and wired in the compressor package. 3. Battery shall be 290 amp hr and cold test current of 790 amp. E. Drive 1. Airend and engine shall be gear driven for low airend speed. 2. Drive shall be flanged for permanent alignment. F. Compressor Control Panel 1. Unit shall have a master switch. 2. Unit shall have a convenient start/stop switch. G. Safety System 1. Instrument panel shall consist of airend discharge temperature gauge, discharge pressure guage, service hour meter, fuel level guage, cooling water temperature guage, oil pressure guage, and malfunction indicator. 2. Compressor shall shutdown in the event of low engine oil pressure and high airend temperatu re. 3. Unit shall have an engine start and stop switch, and the unit shall shutdown immediately if malfunction occurs. H. Standard Package Equipment 1. Compressor shall be enclosed in a galvanized, automotive finish steel enclosure. 2. Access doors shall open and remove easily to provide convenient access to all components. 3. Fixed, heavy-duty towbars shall be used. 4. Coupler shall be either a 2 in. ball or 2.5 in. I.D. pintle ring. 5. Suspension system shall be of torsion bar design for better handling and ground clearance. 6. Wheels shall be 6 bolt, 14 in., with 215 R 14 C tires. 7. Unit shall have DOT approved lighting and reflector package with a flat 4-prong connector. 8. Center-balanced lifting hook shall be standard. 9. Three 1 in. and one 2 in. NPTF compressed air discharge connection with isolation valve and automatic bleed-down f or any attached hose lines shall be used. 10.
