Selecting the right size filter for the job

Inlet Filter

Disc filter diameter is commonly determined by the volume and viscosity of the sample passing through it. It is important that the effective filtration area (EFA) of the media is enough to process the sample without effecting the desired flow rate.

Filter Size Effective Filtration Area
24mm 4.52 cm2
25mm 4.90 cm2
50mm 17.35 cm2

Through close consultation Helapet can help determine the right size filter for your requirements, taking into consideration the volume, viscosity and speed of the sample being processed, which will achieve the following associated benefits:

  • Appropriate size filter to handle sample flowrate
  • Maintain flow efficiency without the risk of hold up or premature clogging
  • Maximise space efficiency and compatibility as part of an instrumentation system

Encased in our quality polypropylene housing


Helapet provide a choice of filter housing sizes, all manufactured using FDA approved virgin Borealis polypropylene based on its excellent chemical compatibility and low lint properties. Our filters are used to support low flow filter applications across several industries where contaminant-free filtration is essential.

Quality filters for quality filtration


Quality is vital when manufacturing filtration devices for specialist manufacturing processes, avoiding the risk of chemical or particulate contamination Helapet operate all our production machinery and moulds from our Dunstable HQ in the UK. We work to the highest level of in-process quality controls and monitoring, producing all our filter components within a controlled ISO rated cleanroom environment.

To guarantee the performance of our filters, we use the latest injection moulding technology to form the connections and over mould the housing seals of our 50mm filters to withstand higher pressure requirements. Ultrasonic welding enables our media to be secured without the use of chemicals, ensuring the filtrate enters the media avoiding potential problems with bypass or contamination.
