There are several different types of blowers in the market. In many applications, air flow and pressure (or vacuum) level requirements may determine what type of blower should be used. There are many areas however, where there may be over-lapping in performance capabilities. It is those areas, this may require a more in-depth evaluation of blowers that could potentially be used. The performance ranges that are likely to require additional consideration are in the volumetric capacities up to 1000 CFM, pressures up to 8 PSIG, or vacuum levels to around 15” Hg. Some of the common blower choices in these… Read the rest
- “Power” applications include such things as air tools, air cylinders, air motors and devices that require compressed air to actuate a mechanical component.
- “Process” applications include processes where air is being mixed with, or is in direct contact with a chemical, gas or product to agitate, fluidize, convey, clean, shape or in some manner, finish the final product.

Regenerative blowers offer several performance benefits, making them a popular choice for moving air volumes up to approximately 1000 CFM at elevated pressures. They are robust, compact, lightweight, maintenance free, and offer efficient performance. What else? With quiet operation and good mechanical efficiencies for moving air, you will find them the most economical way to satisfy your application requirement when compared to positive displacement blowers. With these notable features, these blowers are chosen for applications in varied industrial sectors. Let us examine those industries that make use of the beneficial features of regenerative blowers.

There are several processes requiring low pressure air in industrial and commercial applications. To carry out these processes efficiently, regenerative blowers have become a widely used source for low pressure air. These blowers are common for small air volumes at higher pressures, which are beyond the performance range of centrifugal blowers. Regenerative blowers, unlike centrifugal blowers, operate on compressor laws as opposed to fan laws. Under compressor laws, increases in pressure or vacuum levels result in a higher workloads, and greater heat generation. As pressure or vacuum increases, the volumetric capacity of these blowers decreases. This is the opposite of … Read the rest
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.
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 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
- 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
