Filter Media Test Rigs » MFP system

Modular filter media testing system for quick determination of fraction separation efficiency, burden and pressure loss in accordance with the standards and based on customer requirements

With the MFP series, Palas® offers high-precision testing systems for the development and quality control of filter media. From HEPA qualities with high separating efficiency to pre-filtering qualities, the test rigs in the MFP series deliver clear, fast and therefore cost-effective testing results.

Based on the test requirements specified in standards like EN779, ASHRAE 52.2, DIN 71460-1, ISO TS 11155-1, ISO 5011, EN 1822, ISO 29463 or based on special practical requirements, the MFP test rigs are equipped with different systems for aerosol generation, electrical discharge of aerosols, aerosol dilution and air humidifiers.

The clear determination of the fraction separation efficiency is performed highly accurately using the aerosol spectrometers Promo® 1000, 2000 and 3000. The wide range of interchangeable welas® sensors allows the measuring system to be perfectly fine-tuned even for particle concentrations up to 1 g/m3 with SAE dust in accordance with ISO 12103-1.

The MFP series is used with great success all around the world.
