Many Sources for Basic Air Compressors
As with any other business asset, vendor selection for air compressors should be a careful and deliberate process. This is especially important if a large, expensive unit is required. Important criteria to consider are price, location, service policy, and reputation. If searching for a small, lower-end air compressor, it may be found locally at a national hardware chain such as Home Depot or Lowes. Sears also has an extensive line of Craftsman air compressors. All of the big chains and many locally-owned or franchise operations such as True Value are competitive on price and provide good service. Nearly all air compressors are covered by a manufacturer warranty. If getting a bargain is essential, used or reconditioned units can be found locally or listed on the Internet.

Need a Larger Air Compressor? Specialized Dealers May be Required
Upon determining the need for a larger air compressor than is available at the sources above, it is usually necessary to contact dealers or manufacturers who specialize in two-stage air compressors or rotary type units. There are a number of American manufacturers who make high-capacity air compressors, and an even larger number of worldwide providers. If a business relationship with an industrial machinery broker is already established, it may be convenient to enlist the brokers assistance in getting the best deal on an air compressor that will suit business needs. Without a broker, there are a variety of websites that list air compressors and other equipment from a various manufacturers. Both new units and factory-reconditioned air compressors are listed on these sites. Examples include the Northern Tool andamp; Equipment Air Compressor Buyers Guide, the Industrial Quick Search Directory, and the Industrynet Industrial Buyers Guide.

How About Service?
Service is a key component in the acquisition of any large piece of equipment, particularly if purchasing a high-capacity, expensive air compressor. Not only is there a large investment to protect, but an inoperable air compressor can severely impact a business if it is relied upon for many tasks. Maintenance staff can take care of routine maintenance with information in the air compressor service manuals. If no maintenance personnel are on staff, a business owner may want to look into a service contract or extended warranty. Make sure the terms of any service contract are clearly specified, including charges for parts and labor, and most importantly response time for line down situations.
