Industrial Air Compressors

Frequently Asked Questions

One of the first questions you need to ask when looking to purchase an air compressor is whether you need a piston or a rotary screw compressor. Each compressor is very different in design and is often used for different applications.

Piston Air Compressor

  • Piston air compressors have a cheaper upfront cost than its counterpart, however, it has higher maintenance costs
  • Cost-effective and great for short-term or intermittent domestic and light industrial use
  • Piston air compressors are usually smaller in weight and size
  • Operates intermittently and therefore it is not good in situations where you need a constant flow of air
  • Only requires simple maintenance

Screw Air Compressor

  • Rotary screw compressors have a higher upfront cost but lower maintenance costs over their lifetime
  • Provides a constant flow of high volume compressed air
  • More popular for manufacturing and heavy-duty industrial applications
  • Screw air compressors are not suitable for use in short bursts
  • Operates at a much lower temperature than a piston compressor

An oil-free compressor usually costs more and last for a shorter amount of time. However, in a situation where you need a completely oil-free environment (such as in food industries where there is a chance of contamination), oil-free compressors are the only option. Here are a few key points to consider when deciding which type of air compressor is right for you.

Oil-Injected Air Compressor

  • Oil-injected air compressors are often quieter in operation
  • Not suitable when you work in an industry that required a completely oil-free environment due to its oil carryover
  • Most common screw compressor in Australia
  • Will last much longer than oil-free screw compressors
  • Oil injected tend to be the most cost-effective air compressors

Oil-Free Air Compressor

  • Oil-free compressors are generally more expensive than oil-injected
  • Provides 100% oil-free air
  • Oil-free are compressors are more expensive for servicing and repairs
  • Lower life expectancy

What size compressor you need is completely dependent on what air-operated equipment you plan on using. To work out what size would be best for you, add up the air usage of all air tools that will be used simultaneously. It’s best to add an extra 20% - 25% to allow for future usage down the track. This is only a rough guide, the best way to ensure you have the correct size machine is to request a compressed air energy audit.

No, they do not. It’s always best to check for any problems after the first start-up but after that, you are ready to go. If you do find any leaks or problems, turn the machine off and be sure to contact your product provider before operating any air compressor equipment again.

Many air compressors are able to run off generators, however, it is not recommended. If you have access to mains electricity, it is recommended you use that to power your air compressor equipment. Generators have fluctuations in power which can cause problems for compressors as they require a constant voltage to run. It is even more important for rotary screw compressors to be run off mains electricity rather than generators due to their constant operation.

Oil change frequency usually depends on the specific model of air compressor. The best way to assure it is being changed adequately is to read the recommended schedule in the owner’s manual. If you do not have access to an owner’s manual, the best way to find your answer is to contact your provider with the model number of your machine.

If you are only using your machine occasionally then annually servicing your compressed air equipment should be sufficient. If you are operating your air compressor routinely, then it may be best to service it quarterly. It is always recommended to do small services whenever you have the ability and time to.

If you are ever worried that your air compressor is not working the way it is intended, it is always safest to turn it off and have a trained industry professional come and inspect its components.

When looking to improve energy efficiency, customers have to look further than the air compressor and evaluate the compressed air system as a whole. The most essential part for improvement is generally your air piping system — how the compressed air is transported and used in the end application. Both the design of the distribution and the material used for piping affect energy efficiency. Consult with a compressed air specialist to see what steps can be taken to pursue reduce your energy cost. By running an energy-efficient operation, your business works toward saving money and creating a more sustainable future.

 

A rotary screw air compressor works by forcing air through a pair of rapidly rotating helical screws (or rotors). Powered by the air compressor motor, the two rotors, one female rotor and one male rotor, move in opposite directions. As the male and female rotors turn, they interlock, creating a series of chambers. This causes a vacuum, which pulls more air into the chamber through the air compressor air intake. As air moved through the successive chambers of the paired rotors, it is squeezed into a smaller volume, resulting in compressed air. Finally, the compressed air exits the screw unit, where it can be captured, dried, filtered, and used or stored.

There are two basic types of rotary screw compressors, oil-injected and oil-free.

 

OIL-INJECTED ROTARY SCREW COMPRESSORS

  • Oil-injected screw compressors are the most common type of rotary screw air compressor and work well for most industrial applications.
  • An oil-injected screw compressor utilises oil to lubricate the screw unit and ensure a smooth operation.
  • The oil is also used to help cool the compressed air and prevent the unit from overheating. After the air has been compressed, the oil is removed using an oil separator.
  • A small amount of oil may be left in the compressed air (oil carryover), which can be further reduced using inline filtration.

 

OIL-FREE ROTARY SCREW COMPRESSORS

  • An oil-free rotary screw air compressor uses a two-stage compression process. Air passes through an intercooler between the two compression stages to bring temperatures down and prevent overheating.
  • Oil-free rotary screw air compressors eliminate any oil carryover, producing very clean high-quality compressed air.
  • However, oilless rotary screw compressors tend to be more expensive, noisier, and more complicated to maintain compared to oil-injected rotary screw compressors.

A rotary screw air compressor is one of the two types of positive displacement gas compressors, with the other being the piston air compressor. It uses a pair of enmeshed helical screws to compress air. As the screws turn, the air is continually compressed.

Rotary screw air compressors are widely used for applications that require high CFM (cubic feet of air per minute) continuous use (100% duty cycle). Due to this, it is the most commonly used air compression technology for heavy industrial applications such as powering pneumatic production lines and conveyor systems. Rotary screw air compressors are one of the easiest types of air compressors to operate and maintain.

Rotary screw air compressors are best for applications that require continuous use or high CFM. Oil-free rotary screw compressors are also a good choice for any application that requires very clean air. Some industries that commonly utilise rotary screw air compressors are:

  • Food and beverage industry
  • Hospitals
  • Manufacturing

Below are the basic components of a rotary screw compressor:

AIR-END (PUMP)

The air-end is where the work of air compression happens inside the rotary screw air compressor.

AIR INLET VALVE

Where atmospheric air comes into the air-end for compression.

ROTORS

A pair of interlocking helical screws that rotate rapidly to compress air.

COMPRESSION CYLINDER

The housing that contains the rotors. A rotary screw air compressor may have a single compression cylinder or multiple cylinders for multi-stage compression. Oil-free compressors will also have an intercooler between each compression cylinder.

DISCHARGE VALVE

Where compressed air exits the air-end. Air may go from the discharge valve to an air receiver tank or directly to air-using processes.

BEARINGS

Bearings on both rotor ends help the rotors to stay in place and turn smoothly and rapidly. Bearings are typically anti-friction and corrosion-resistant.

 

HIGH CFM

  • Compared to piston air compressors, rotary screw air compressors can produce more compressed air (measured in cubic feet per minute, or CFM) per horsepower. That means they use less energy for producing the same volume of compressed air.

CONTINUOUS USE

  • Rotary screw compressors are designed to compress continuously and operate best at 100% duty cycle, making them a great choice for 24/7 production operations.

CONSISTENT AIRFLOW

  • You can also count on a rotary screw air compressor for highly consistent airflow, so you can size your air compressor very close to your maximum use scenario.

LOWER OVERALL COST OF OWNERSHIP

  • A rotary screw air compressor costs more upfront but will save money in the long run.
  • In addition to lower energy costs due to their higher CFM output, rotary screw compressors will generally last longer than piston air compressors.

CLEANER AIR

  • A rotary compressor will deliver very clean air with low oil carryover.
  • An oil-injected rotary screw compressor will have an oil carryover of ~3 ppm. Oil-free compressors, of course, have no oil carryover.

QUIETER OPERATION

  • Compared to piston compressors, screw compressors are overall quieter. This is because the action of the rotary screws is quieter than the action of moving pistons. Additionally, screw compressors often have a sound-damping enclosure.
  • A typical rotary screw air compressor will operate at 65-75 dBA, or somewhere between the noise level of a car engine and a vacuum cleaner.

COOLER TEMPERATURES

  • Lower operating temperatures translate to less work for coolers and air dryers, resulting in further energy cost savings.
  • Internal operating temperatures for a rotary screw air compressor range from roughly around 26°C to 37°C.
  • For comparison, a piston compressor typically operates at an internal temperature of roughly 65°C to 93°C

SPACE SAVINGS

  • A rotary screw air compressor generally takes up less floor space than a piston air compressor at similar CFM output.
  • In manufacturing facilities where floor space is at a premium, this can be a huge advantage.
