Air Power Products Limited has received the ISO 9001:2015 Certification in January 2018.
Cambridge, Ontario- February 27, 2018 – Air Power Products Limited, a leading manufacturer and distributor of lubricated and oil-less air compressors, vacuum systems, regenerative blowers, regenerative compressed air dryers and other associated products, has announced that it has achieved certification status under the ISO 9001:2015 standard, as of January 2018. The company had earned its first ISO 9001 certification in February 2001, under the ISO 9001-2000 standard.
The ISO 9001:2015 is a revision/upgrade to the ISO9001-2008 standard. This standard is devised by International Organization for Standardization, which … Read the rest
What are regenerative blowers? They are modern-day machines. Compact, and versatile, they are specially designed for moving a large volume of air, which is at low pressure.
Regenerative blowers provide an alternative means of compressing or evacuating small volumes of air at positive or negative pressures. They initially filled a performance void between centrifugal blowers and positive displacement (rotary lobe) blowers. With improvements over the years in pressure capabilities, they may now replace rotary lobe blowers in many applications, based on the many other benefits they offer.

In our efforts to continually improve, Air Power Products Limited wish to make our sprinkler system customers aware of pitfalls when sizing sprinkler system air compressors. One main focus for our air compressors, or any others for that matter, is to ensure that the compressor does not cycle on and off too frequently. Excessive motor starts will result in motor fatigue and premature failure. For sprinkler compressors, we recommend the following as the maximum number of starts per hour:
½ HP motors = 14 starts per hour
1 to 5 HP motors = 10 starts per hour
This is … Read the rest
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.
- Air Intake Filter: It is a basic concept that in order to compress air, you must be able to intake air to the compression

There are several types of oil-less air compressors available on the market, and the selection of a 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 … Read the rest
Air burst systems are a standard requirement for municipalities and industries that draw water from rivers, lakes or ponds. The air burst system is designed to keep intake screens below the water level clear of debris and silt which accumulate as a result of inward water flow. The basic principle is to displace these materials with a high volume blast of compressed air in reverse flow direction through the screens. The systems are normally designed to be automatic and operate on a timed basis, calling for an air burst usually once or twice a day, or as required/established, depending upon … Read the rest
Air Power Products Limited has been supplying our “Purge Economizer Control$” systems for over 25 years. The original intent was to supply our customers with a system that not only save compressed air, but would also indicate what those savings amount to. The second initiative was to provide these features at a reasonable cost that would provide a quick ROI for the user. That was 25 years ago! Today the issues of saving compressed air is of even greater importance as the cost of electrical services rise. Not only are these issues recognized by compressed air users, but they are … Read the rest
When it comes to proper desiccant dryer performance one of the most common culprits resulting in poor dew point performance, is lack of prefilter maintenance and/or faulty prefilter drain operation. Most oil coalescing prefilter elements should be replaced at 2000 hours of service. Without a disciplined PM schedule to replace these elements and to confirm proper prefilter bowl drain operation, you run the risk of contaminating the desiccant bed.
Manual drain valves on the bottom of these filters are often problematic when not drained in a timely fashion, allowing oil to re-entrain into the airstream, causing oil to enter the … Read the rest
When it comes to properly sizing a dryer, there are some misconceptions that often lead to incorrect, or over-sizing of a compressed air dryer.
Most people charged with the responsibility of designing the compressed air system or installation of a correctly sized air dryer, typically match the inlet capacity with the compressor maximum output. This is especially incorrect when sizing for an air-cooled reciprocating air compressor. Reciprocating air compressors are typically air cooled, and use pitched vanes on the pump flywheel which drive cooling air across finned cylinders to allow/assist in the air cooling and heat dissipation. These pumps are … Read the rest
Lubricated reciprocating air compressors, like an automobile, require regular oil changes to ensure that bearings and piston skirts are receiving clean lubricant to prevent metal to metal contact. Most small reciprocating compressor manufacturers recommend oil changes every 12 months or 500 hours – whichever comes first. Many small reciprocating air compressors may operate on single phase power directly fed by a breaker. Three phase models may use an economically priced off-the-shelf magnetic motor starter. In both of these scenarios, there is usually no provision made to log hours on the compressor.
