A rotary screw compressor is one that utilizes two intermeshing helical rotors to trap a volume of air, and then compress it to a higher pressure. Rotary screw compressors can be run at lower temperatures for 24 hours per day, 365 days a year.

A piston compressor uses pistons driven by a crankshaft to deliver air at high pressure.

This is actually quite an easy fix - you need to add a pressure regulator to your line, which can be set for the desired pressure when the air reaches your tool.

Compressed air is a popular energy source for many application. The main benefits of using air compressors and compressed air are:

• Improved productivity

• Safe & easy to use

• Energy efficient

• Low operating costs

• Versatile tools & applications

Always choose a compressor with a bit more than you need. The most important factor is the volume of air (m3/min or cfm) that you will be using and at what pressure. Please give us a call to work out your required m3/min or cfm (FAD) figure for your factory and then choose a compressor will at least that rating.

Air pressure is determined by the highest minimum pressure requirement. For example, some tools consume more air than others. Tools such as pneumatic nail-guns and staplers consume smaller amounts of air, while air grinders and sprayers consume larger amounts. Most tools have an usage rating for CFM consumption at a recommended BAR. This can be found on the tool itself or in the owner's manual supplied by the tool manufacturer

The notation CFM (Cubic Feet per Minute) refers to a volume of air produced by the air compressor at a given pressure or BAR. The right size air compressor will meet your needs in two essential areas: air flow (CFM) and pressure (BAR). It's important to get a compressor that meets your needs in both areas - otherwise you risk damage to both your tools and the compressor itself. Always use CFM and BAR specifications from the nameplate on the product.

No, this is not up to the approved code for compressed air systems. The PVC is an oil based product and it does not react properly to heat, vibrations and oil vapour that is carried in the air compressor discharge air. The PVC is prone to bursting under the normal air pressure and unit operations. Please consult us for piping recommendations.

Yes! You can purchase an automatic drain valve. There are 2 main types of automatic drain valves, including float actuated or electrical timed sequence actuated.

The recurring maintenance intervals depend on the actual operating hours and time. This means that a compressor that does not reach its operating hours within 6 or 12 months or until the next recurring maintenance, it still needs a service as various wearing parts and filters are subject to an ageing process. With special consideration of the operational safety and the guarantee of a trouble-free operation, it is recommended to observe the specified maintenance intervals depending on the type of plant. Minimum interval is 1 time per year.

Yes. JKKP Malaysia required the air tank to be serviced and inspected annually. 

Depending on the filter element and function, the filter elements should be changed every 6000hrs or 12 months whichever comes first depending manufacturers’ recommendation. 

Why should I replace my filter element regularly? In order to ensure a continuous supply of high-quality compressed air and to reduce energy costs, filter elements must be replaced regularly.

In principle, compressor oil approved by the plant manufacturer must be used. The compressor oil is the greatest importance in the compressor system (for oil-lubricated screw compressors). The oil in the system is mainly for lubrication, cooling, sealing clearances and anti-rust. However, it also needs the property to be separable again afterwards. Depending on the application of the system, mineral oils can also be used as synthetic or food grade oils. 

Generally this is caused by two problems - either a failed condensate trap or a failed or undersized air compressor dryer. To solve the first problem, you will need to either clean the water trap or simply replace it. The second problem is a bit trickier, as you would need to repair or replace your air dryer with larger capacity. 

There will always be a certain amount of oil carry over from a oil lubricated compressor. When the compressor it is running hot or is being over worked, oil carry over is made worst. The hot oil fumes and then condenses in the hose and in the tools. The affect can be reduced by running the compressor as cool as possible, making sure there are air/oil separator’s condition is good, minimum pressure valve is functioning well and that the outlet pressure regulator on the compressor is set as low as possible. Ensure there is plenty of ventilation. A coalescing filter can also be used to reduce oil and condensate.

An air dryer reduces the amount of water suspended in the air. Hot air holds more moisture, so the ideal system for the maximum removal of water is a refrigerated air dryer or desiccant dryer depending on the application. For example, a 10 hp compressor with air entering the system at 24 degrees C and 75% relative humidity produces water at the rate of 24 litres per day. A refrigerated air dryer would remove a total of 23 litres of water (leaving only 1 litres in the system). 

Low oil levels can cause your air compressor to be running hot. Check the oil level as your first step and add compressor oil. If the over-heating is not corrected by adding oil, then rule out ambient temperature that is too high; a restriction in the system’s air or water flow; or ventilation around the compressors working area.

The Compressed Air & Gas Institute (CAGI) cites 10 contaminants that typically need to be removed or reduced from low-pressure compressed air used for manufacturing (not breathing air). These contaminants fall into four general categories:

• Particles (from pipe scale, wear particles and atmospheric dirt) 

• Water (liquid, vapour and aerosol)

• Oil (liquid, vapour and aerosol)

• Microorganisms

The international standard ISO 8573-1:2010 is a compressed air quality specification that addresses these very same specific contaminants by providing a range of purity classes for particles, water and oil. It does not include classes for gases or microorganisms.
