Air Filters for Heating, Ventilation & Air Conditioning (HVAC)

Particle Technology filter
Air filters are the critical component in HVAC systems, providing clean breathable air to the indoor environment. The health hazards associated with respirable particles are now better understood, therefore, specifying the correct HVAC filter for the intended application is now more critical than ever. Our accredited laboratory in the UK can determine the essential performance characteristics of initial efficiency, discharged efficiency, air flow resistance (differential pressure across the filter), test dust capacity and arrestance. This information is presented in a formal test report, which includes the official filter classification of either G1 to F9 in accordance with EN 779:2012, or an ePM1, ePM2.5, ePM10 and ISO Coarse classification in accordance with ISO 16890:2016.

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:

  • A 35 kW fan that can generate up to 17,000 Pa of pressure at 3400 m3/hr or 14,000 Pa at 5400 m3/hr.
  • Oil and salt aerosol generators from PALAS and TSI to determine filter efficiency.
  • Upstream and downstream particle counting conducted using a PALAS Welas 3000 particle counter with a measurable range of 0.2 µm to 100 µm.
  • TOPAS TDC 584 cabinet for the IPA vapour discharge test in accordance with ISO 16890:2016-4.
  • TOPAS SAG 440 dust feeder for dust concentrations including 70 mg/m3 or 140 mg/m3 depending on the test standard.

Air Filters for Gas Turbines

With our bespoke duct insert, we can test cone or cylinder filter elements in accordance with EN 779:2012, and also ISO 16890:2016 if desired. The TDC 584 cabinet for IPA vapour discharge can accommodate individual filter elements up to 1000 mm in length. We carry out extended testing beyond the requirements of the standards to reach final differential pressures of up to 6000 Pa and elevated dust feed rates.

Air Filters for Internal Combustion Engines & Compressors

Testing to ISO 5011:2014

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 differential pressure across the filter at a specified air flow rate, particle removal efficiency, arrestance and test dust capacity.
Particle Technology Ltd has many years of experience in air filter efficiency testing to international standard ISO 5011. In addition, we can perform tests using a range of materials to suit different applications, and have a selection of calibrated dust feeders available which enables dust concentrations to be controlled from a few mg/m3 up to hundreds of g/m3.
If you are testing big or small air filters and you do not have a filter housing available then we can design and manufacture bespoke filter housings to meet your demands. This can be especially useful if the filter comes from a large machine where the filter housing may be incorporated into the machine and cannot be easily removed for testing.
