Simple and effective way to filter your air, removing water, oil and other suspended debris. Offers energy savings, high flow rates and ease of use. Easy to install and maintain. All units come with mounting bracket, auto drain and polycarbonate bowl guard with sight glass. *Please note that you need a 2 Bar differential (30psi) to seat the drain to the filter upon start up so if you are running a very low pressure system please ensure you have this.

  • What is an Air Filter?

    An Air Filter unit is used in compressed air systems to protect pneumatic control valves, actuators, pneumatic tools, and HVAC from in line contamination. The Air Filters function is to increase performance and reduce maintenance from pipe scale, water condensate and burnt compressor oil. The unit is sold with mounting brackets and automatic float drain.

  • How does a Compressed Airline Filter work?

    Air enters the filter and is spun around the bowl with vanes mounted in the air flow causing a centrifugal action. Water and condensate collects at the bottom of the bowl where it is drained away via an automatic float assembly. This condensate is protected in this area from being picked up in the air flow by a baffle which creates a ‘quiet zone’. The filter bowl is polycarbonate with a guard allowing visual inspection of the condensate. The air continues up through a filter element which is usually 5 micron. This removes dirt particles from the air flow. The air then continues through the filter and into the main system.

  • How do I size an Air Filter?

    The units are sized according to their port sizes (¼” - 1” Bsp). The usual method is to match the port size of the pipe that is feeding the equipment i.e. ½” tube supply will be a ½” Bsp Filter. The other method is to work out the required flow rate for the equipment to be serviced with the rating of the Filter plus a 30% safety factor. Pressure range is 0.5-8.5 Bar and working temperature to 60 degrees celsius.

  • How long will my Compressed Air Filter Last?

    Cleaning of the filter element is dependent upon the amount of contamination in the air supply. Regular maintenance should be scheduled to clean the filter. However this frequency will be subject to individual applications. With few moving parts and scheduled maintenance these units will last decades.

  • How do I install a Filter?

    The unit is mounted horizontally in the direction of flow (as marked on the body). The filter bowl must be vertical to operate. Mounting brackets hold the assembly at either end and can be mounted onto any convenient structure.

  • What are typical uses of a Compressed Air Filter?

    The air filter unit is used in compressed air systems to deliver clean air to pneumatic control valves, actuators, pneumatic tools, and HVAC systems. They protect valuable instruments and tools from internal damage due to contamination in the air ring main. The Air Filter Unit function is to increase performance and reduce maintenance from pipe scale, water condensate and burnt compressor oil.

  • How long will my product take to get to me? 

    This depends upon where you are based and the freight method chosen. If the express freight option is selected it is usually next day delivery to metropolitan areas in Australia for under 5kg. If free freight has been selected it will go by road freight which can be anywhere from 1 to 10 days depending upon your location. It usually averages 3 days.

  • What warranty do I get?

    All of our products come standard with a 12 month warranty. The good news is we have very strict quality controls and all Filters leave our warehouse tested and inspected so there are rarely any issues. Also once your Filter is in and operating it will most likely continue to do so for a very long time barring any external factors.
