designed for heavy shop or industrial use, ingersoll rand electric-driven two-stage air compressors provide the reliability and performance that are ideal for most applications and users including automotive service and body shops, fleet maintenance, machine shops, production and manufacturing lines, wood working shops, dry cleaners, car washes, general maintenance/repair shops and farms.
two-stage compressors consist of one or two first-stage cylinders with the same bore size and one second-stage cylinder with a smaller bore size.
ingersoll-rand’s standard two-stage lubricated air compressors are single-acting, air-cooled machines. typical compressors are furnished as compact, self-contained, air receiver tank mounted units that are automatically regulated and driven by an electric motor or gasoline engine. an air-cooled aftercooler, low oil level shutdown switch and automatic drain valve are among the optional accessories that can be furnished. bare compressor pumps and baseplate-mounted units are also available.
ambient temperature considerations.
ideal operating temperatures are between 32°f and 100°f (0°c and 37.8°c). if temperatures consistently drop below 32°f (0°c), install the compressor in a heated area. if this is not possible, you must protect safety/relief valves and drain valves from freezing. if temperatures are consistently below 40°f (4.4°c), consider installing an external crankcase heater kit, especially if the compressor has difficulty starting.
•caution never operate the compressor in temperatures below -15°f (-26.1°c) or above 125°f (51.0°c).
humid areas. in frequently humid areas, moisture may form in the pump and produce sludge in the lubricant, causing running parts to wear out prematurely. excessive moisture is especially likely to occur if the unit is located in an unheated area that is subject to large temperature changes.
two signs of excessive humidity are external condensation on the pump when it cools down and a “milky” appearance in petroleum lubricant.
you may be able to prevent moisture from forming in the pump by increasing ventilation, operating for longer intervals or installing an external crankcase heater kit.
installation selecting a location
electric motor units. for most electric motor units, select a relatively clean and dry well-lighted indoor area with plenty of space for proper ventilation, cooling air flow and accessibility. provide 1,000 cubic feet of fresh air per 5 horsepower. locate the unit at least 15 inches (38 cm) from walls, and make sure the main power supply is clearly identified and accessible.
unless the electrical components of the unit are specially protected for outdoor use, do not install an electric motor unit outdoors or in an area that will expose the electrical components to rain, snow or sources of appreciable moisture.
receipt & inspection
ensure adequate lifting equipment is available for unloading and moving the unit to the installation site.
- lifting equipment must be properly rated for the weight of the unit.
- lift the unit by the shipping skid only. do not use the motor lifting eye to lift the entire unit. the motor lifting eye is for removing the motor from the unit only.
- do not work on or walk under the unit while it is suspended.
before signing the delivery receipt, inspect for damage and missing parts. if damage or missing parts are apparent, make the appropriate notation on the delivery receipt, then sign the receipt. immediately contact the carrier for an inspection.
all material must be held in the receiving location for the carrier’s inspection.
delivery receipts that have been signed without a notation of damage or missing parts are considered to be delivered “clear.” subsequent claims are then considered to be concealed damage claims. settle damage claims directly with the transportation company.
if you discover damage after receiving the unit (concealed damage), the carrier must be notified within 15 days of receipt and an inspection must be requested by telephone with confirmation in writing. on concealed damage claims, the burden of establishing that the unit was damaged in transit reverts back to the claimant.
read the unit nameplate to verify it is the model ordered, and read the motor nameplate to verify it is compatible with your electrical conditions. make sure electrical enclosures and components are appropriate for the installation environment.
