Swan Oil-Less Air Compressors

Swan oil-less air compressors are a proven work horse. The requirement and advantages of oil-free compressed air has been noted in other blogs, so we will not cover all of the advantages.

It is worth re-stating however, that municipal regulations with regard to the disposal of oil-laden condensate, and the changing and disposal of waste oil, continues to be a costly feature for maintaining lubricated compressors. Most municipalities will not allow the draining of oil-laden condensate into city sewage systems. That necessitates the use of condensate/oil separation systems as part of any lubricated compressor system.

The routine of changing oil and having waste oil, plus the removal of oil and/or oil contaminated elements from separator systems, will require proper disposal, which will all require the time of maintenance personnel. This is where the Swan oil-less compressor will reap benefits, especially where clean air is imperative.

What to Consider for Oil-less Air Compressor Maintenance?

In the previous post, we outlined some of the considerations for selecting either a reciprocating or rotary scroll air compressor. One of the major considerations will be the routine maintenance, which in turn will affect the “Cost of Ownership over a specified period of time”.

Maintaining Oil-less Air Compressors, Reciprocating and Rotary Scroll

Both reciprocating and oil-less air compressors require very little maintenance. The following items are basic requirements for either type of compressor.

  1. Air Intake Filter: It is a basic concept that in order to compress air, you must be able to intake air to the compression chamber. Air intake filters protect the compressor from ingesting contaminants that may cause cylinder and piston ring wear or damage, or cause intake and discharge valves to malfunction. As the filter becomes restricted by contaminants, the compressor will lose capacity. Depending on the cleanliness of the location, and the amount

Oil-less Air Compressors- The Evolution in Air Compression

Early Designs

There are several types of oil-less air compressors available on the market, and the selection of aOIL-LESS-COMPRESSORS compressor will usually be determined by the application’s volume and pressure requirements, and in some cases, how and where the air will be used. The industry has changed over the past 50 years, and going back to times prior to the 1970’s, most oil-less air applications for standard pressure (up to 125 PSIG) were serviced by reciprocating air compressors. For large industrial applications, these compressors were available in the single stage (for pressures to approximately 100 PSIG) and 2-stage machines (pressures above 100 PSIG). For high volume applications, these machines were usually massive, with cast iron frames, and were water cooled by way of cooling jackets in the compression cylinders and heads. Most of these machines were double-acting (compressed air on both the upstroke and down-stroke of the piston) using a … Read the rest


Oil-less Air Compressors for Zero Oil Contamination

A variety of air compressors are available in the market of which oil-less air compressors are used to provide oil-free compressed air. They are used in critical operations, where products or processes could become contaminated if subjected to small amounts of oil. Contamination may result in costly scrapping of product and/or production downtime to clean or purify the system. Oil-less compressors may also be used with additional purifying filtration and safety controls to produce air for breathing applications in industry and medical systems.

oilless compressors

Oil-less reciprocating air compressors consist of dry compression chambers using synthetic self-lubricating guide rings and piston rings. The lower end running gear employs sealed main ball bearings and sealed connecting rod bearings so no oil is used in the crankcase. The complete absence of oil in this design eliminates the possibility of oil migration from the crankcase to compression chambers, which may be a concern in compressor … Read the rest
