Compressed air filter test bench
The Compressed Air Filter Test Bench is a fully automated system designed to measure the fractionation efficiency of compressed air filters at overpressures up to 7 bar. It provides highly accurate and reproducible testing that exceeds the requirements of ISO 12500. The system integrates the aerosol spectrometer, featuring a pressure-resistant aerosol sensor capable of measuring both feed and clean gases, ensuring precise determination of particle size and concentration without the need for dispersers or dilution. Additional filter funnels are available for testing plate media.
Application
TheAir Filter Test Benchis suitable for testing complete compressed air filters, evaluating filter media, and determining emissions during loading. It supports laboratories and production facilities in quality control, product development, and R&D activities. The system accommodates a wide range of aerosols, including oil-based and solid particles, and is capable of testing at elevated pressures up to 10 bar, providing results that are internationally comparable and compliant with multiple standards.
Standards
(1) EN 779 / ASHRAE 52.2 – General ventilation air filter testing
(2) DIN 33891 – Vacuum cleaner testing
(3) DIN 71460 – Automotive air filter testing
(4) HMT-1000 – Oil mist separator testing
(5) Scanning HEPA filter leak detection and efficiency measurement systems
Features
1. Mobile testing unit with portable clean gas and easy filter replacement: The mobile clean gas unit allows for easy use of filter housings of different sizes.
2. Variable aerosol generation: Different dispersers are used for DEHS, dust, etc., enabling shorter measurement times, for example, by increasing aerosol concentration.
3. Wall-flow separator: A drain valve prevents oil particles separated from the feed gas pipe wall from entering the filter housing.
4. Light scattering aerosol spectrometer: Used for clear particle measurements directly at overpressures up to 10 bar; the integrated automatic adjustment of sampling volume flow rate under pressure changes ensures accurate measurement conditions.
5. flexible, pressure-resistant aerosol sensors can be used for direct particle measurement of feed gas and clean gas at overpressures up to 10 bar; thanks to the aerosol sensor (finely tuned for different aerosol concentrations in feed gas and clean gas, eliminating the need for a dilution system),
