Filter Testing

Filter Testing
Efficient inlet air cleaning for internal combustion engines and compressors is vital if you are to prevent a breakdown of a road vehicle or compressor. The essential performance characteristics are air flow restriction or differential pressure, dust collection efficiency, dust capacity and oil carry-over on oil bath air cleaners.

Particle Technology Ltd have many years experience in air filter efficiency testing to various standards including ISO 5011, and EN 779. Using our test facilities we can conduct air filter performance testing in a number of formats using a range of test materials to simulate real life conditions.

Filter Testing Facility
Particle Technology have access to a range of fans and compressors allowing flow rates up 3000m3/hr to be achieved. A selection of calibrated dust feeders means that dust concentration can be controlled from a few mg/m3 up to hundreds g/m3.

Palas Welas 3000 particle counters are used to measure the number of particles upstream from the filter and compared with the number of particles down stream from the filter. These industry standard pieces of equipment are used to accurately determine the filtration efficiency at different particle sizes.

Filter Testing Process
If you are testing big or small air filters and you do not have filter housing available then we will design and manufacture bespoke test filter housings ensuring reliable and repeatable results. This can be especially useful if the filters being tested are for large vehicles such as locomotives where the filter housings may be incorporated into the vehicle and not easily removed.
