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.

The Best Controls For Reciprocating Air Compressors

If a reciprocating compressor is selected, there are some special features that should be considered. For any compressor that is going to automatically cycle on and off, further consideration should be given to the number of motor starts that may occur every hour.

In compressors of this size range, the number of starts per hour should not exceed 6 to 8. Excessive motor starts may cause extra stress and over-heating of the motor, which may result in reduced life expectancy or premature failure. This can be controlled in a few different ways.

The first way is to ensure that a suitable volume of air is stored when the compressor shuts down to allow it to be off for a reasonable period of time. The air storage will be determined by two factors – the differential pressure between the start and stop of the compressor, and the size of the air

Considerations for Selecting the Right Air Compressor

When selecting the air compressor that is right for your application, there are a number of issues which should be considered. The basic considerations will be as follows:
  1. What pressure do I need for the optimum performance of the equipment or processes that I am using the air for?
  2. What size air compressor do I require?
  3. What type of compressor should I install – reciprocating, rotary screw, rotary vane or rotary scroll?
  4. Should my compressor be lubricated or oil-less/oil-free?
  5. Will the compressor be in an area where noise may affect personnel working in the area? If so, what options do I have for either noise attenuation of the air compressor, or installing it in an area which is remote from personnel?
  6. Should the compressor be air-cooled or water-cooled?
  7. What electrical power is available to operate the compressor?
  8. How much piping, and what size and type will be required to distribute

Selecting the Right Blower for Your Application

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 ranges may include:

  • Regenerative (side channel) blowers (single stage or 2-stage)
  • Rotary lobe positive displacement blowers
  • Multiple stage centrifugal blowers
  • High speed centrifugal/turbine-type blowers
  • Rotary vane blowers
  • Liquid ring compressors/vacuum pumps
  • Rotary Claw pumps


When applying any of these blower types, some of the considerations may be:

  • Mechanical Efficiency. (which

Compressed Air Purity Levels and Application of Dryers and Filters

In industries using compressed air, there is a requirement to ensure that the air quality meets the standard for its intended use. Compressed air usage is generally broken down into two categories, being “power” and “process”.
  • “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.

Before a dryer can be selected, the air purity requirement must be established. The “International Organization for Standardization” (ISO) has created a table for air purity levels under document 8573.1. This document defines purity levels based on particulate levels, water vapor levels and oil aerosol levels. The first reality, will be to understand that the process

7 Industries that Use Regenerative Blowers

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.

Where are Regenerative Blowers Typically Used?

The following are the industries wherein regenerative blowers are commonly used.


  1. Industry: Manufacturing
  2. Applications: Pneumatic conveying, vacuum transfer, scrap collection, batch processing, air bearing work stations, furnace combustion air, parts processing and packaging.

  3. Industry: Textile

Common Factors that Lead to Failure of 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 centrifugal blowers operating on fan laws, where greater volumes increase the work load, and as pressure or vacuum levels increase, volume is reduced, and the work load and heat load are reduced. Therefore different precautions are required for the protection of regenerative blowers.

Regenerative Blowers: What Do You Know About Them?

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.

A Message to Our Customers – Sprinkler Air Compressors

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 especially critical for single phase motors. The number of starts per hour will of course be determined by the amount of leakage in the sprinkler system. For older systems with substantial leakage, these numbers could easily be exceeded. One of the few controls the designer has to reduce motor starts,
