How to Select and Protect Your Air Compressor Investment
     To most people who select an air compressor, the most important factors are overall cost, efficiency, ease of maintenance, and troubleshooting.
Who Can Fix It?
     If an air compressor system can be serviced by in-house personnel, overall operating costs will be less and downtime will be reduced. The more complex the compressor and compressor controls, the more difficult repairs will be. Selecting the simplest system will save you money.
Easy to Maintain?
     Proper maintenance adds to the reliability and efficiency of the air compressor. A compressor that is difficult to maintain causes problems and costs money. Some air compressors and air compressor components are specially designed for easy maintenance.
Noise and Other Site Requirements?
     Air compressors with low-sound enclosures and vibration isolators can save thousands of dollars in site preparation costs. You may be able to eliminate the expense of a separate compressor room or special foundation.
What's the Warranty?
     A warranty is the manufacturer's pledge to the customer. Make sure you have a comprehensive warranty on your equipment that is backed by solid manufacturer and distributor support.
Maintenance Checklist
Compressor prefilters: Check and clean or replace; service frequency relates to conditions in operating environment.
Compressor oil level: Should be at "full" mark; change per manufacturer's recommendation; DO NOT OVERFILL.
Inlet filter cartridges: Remove and clean or replace.
Drain traps: Periodically check for proper operation.
Check for leaks throughout: Piping and flexible joint packings, control lines, control line fittings, clamps and connectors, valves, air pressure safety relief valves, and pressure gauge connections.
Compressor cleanliness: Maintain in a clean condition; a compressor should never leak oil.
Coolers: Check water quality, flow, and temperature in water-cooled units; check inlet filters and cooler in air-cooled models.
Belt condition: Check for wear or damage and re-tension as required.
Compressor temperature: Should be within manufacturer's limits.
Record service and load hours: Systems that record both service and load hours are easier to maintain and troubleshoot.
