Filtration Testing

 

 

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. We specialise in filter performance testing across a range of applications, including HVAC units, gas turbines, internal combustion engines and compressors.

Air Filtration Testing for HVAC Systems

The Importance of Air Filtration Testing

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

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

Classification & Reporting

Your results will be presented in a formal filter 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 classifications in accordance with ISO 16890

Air Filter Testing

 

Advanced Testing Capabilities

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

  • 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 process
  • TOPAS SAG 440 dust feeder for varied dust concentrations

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 filtration testing, adhering to ISO 5011:2020, ensures accurate evaluations with a range of materials and calibrated dust feeders.

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

Air Filter Test 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 and ISO 16890:2016. We go beyond standard requirements, conducting extended filter performance.
