How Efficient Are Your Filters?

As the only laboratory in the UK to hold UKAS accreditation to ISO 17025:2017 for filter testing, Particle Technology is the recognisable choice for assessing the essential performance characteristics of filters, from HVAC units, gas turbines, internal combustion engines and compressors.

Air Filter Testing for HVAC Systems

Air filters play a crucial role in HVAC systems, ensuring the quality of indoor air. Our efficient air filter testing process covers key parameters, such as:

  • Initial efficiency
  • Discharge efficiency
  • Airflow resistance (differential pressure across the filter)
  • Test dust capacity
  • Arrestance

Your results will be presented in a formal test report, which also includes the official filter classification:

  • (G1 to F9) in accordance with EN 779:2012, or
  • ePM1, ePM2.5, ePM10 and ISO Coarse classification in accordance with ISO 16890:2016

Air Filter Testing

 

Our test facility includes state-of-the-art equipment with the capability to test air filters beyond the requirements of EN 779:2012 and ISO 16890:2016. We have:

  • A powerful 35 kW fan generating up to 17,000 Pa of pressure
  • Oil and salt aerosol generators for precise filter efficiency determination
  • Particle counting using PALAS Welas 3000 with a measurable range of 0.2 µm to 100 µm
  • TOPAS TDC 584 cabinet for IPA vapour discharge test
  • TOPAS SAG 440 dust feeder for varied dust concentrations

state-of-the-art equipment with the capability to test air filters

Additionally, we can design and manufacture bespoke filter housings tailored to your specific needs.

Air filter testing for internal combustion engines & compressors

Efficient inlet air cleaning is vital for internal combustion engines and compressors to prevent breakdowns. Our experience in air filter efficiency testing, adhering to ISO 5011:2014, ensures accurate evaluations with a range of materials and calibrated dust feeders.

For big or small air filters without available housing, we design and manufacture bespoke filter housings to meet your demands.

Air filter testing for gas turbines

Protecting gas turbines from damaging particles is critical. Our bespoke duct insert allows testing of cone or cylinder filter elements in accordance with EN 779:2012 and ISO 16890:2016. We go beyond standard requirements, conducting extended testing with final differential pressures up to 6000 Pa and elevated dust feed rates.
