Compressors pressurize air to drive equipment. There is the AC compressor, and there are other kinds that operate things like nail guns and various hand tools, as well as paint sprayers and sandblasters. Industrial compressors operate stamping or punching machines and automation equipment, but can function on an even larger scale.
When choosing an air compressor you may select a stationary model or a portable air compressor. Of course, compressors also come in various sizes and use a range of electrical and other power sources. In special cases, you may also want to consider airflow and quality, as well as operating temperature. The operation costs are important as well. For mechanical operations, there are three different types of air compressors:
1. The pistons in a reciprocating air compressor compress air into a storage tank. This type works best for intermittent applications, like nail guns.
2. A rotary screw compressor actually has two screws to compress air. This type is functional for continuous-use applications.
3. A centrifugal air compressor includes a turbine to compress air. Usually, only industrial and heavy duty applications call for this type.
Find quality compressors for sale from sources that carry wide selectionsThere are many compressor manufacturers, so don't settle for less that the ideal machine. Look for compressor distributors with wide selections.
Look for the air compressor features that match your applicationDepending on your application, there are a number of air compressor features that could help you get the kind of performance you need. For instance, various types of filters are available; these are especially helpful for food processing and even some industrial applications. There are also driers that remove condensation, as well as coolers that lower air temperature.
Locate replacement compressor parts and accessoriesYou want to get as much use out of your air compressor as possible, which means having the right parts when it's time for a replacement, or quality accessories to diversify your application possibilities.
- The air flow of a reciprocating air compressor usually does not exceed 100 cubic feet per minute (CFM), but single stage rotary air compressors go up to 1500 CFM, and two stage up to 2500 CFM. There is not as clear a limit on centrifugal air compressors, but they apply in applications that require air flow in excess of 1000 CFM.
