The newly developed\u00a0compressed air filter test rig DFP 3000\u00a0<\/b>delivers fully-automated measurements of fraction separation efficiency for compressed air filters under overpressure up to 7 bar, offering better results in the process than ISO 12500. On request we can also supply an additional filter holder for flat filter media. The fraction separation efficiency is measured with the new aerosol spectrometer\u00a0Promo\u00ae<\/sup>\u00a03000 P<\/b>, which is equipped with pressure-resistant welas\u00ae\u00a0<\/sup>aerosol sensors for raw gas and clean gas measurements. The system offers the following advantages (among others):<\/p>\n

\u2022<\/span>\u00a0\u00a0\u00a0Clear determination of the particle size and concentration directly under overpressure up to 10 bar
\n\u2022<\/span>\u00a0\u00a0\u00a0Automatic adjustment of the sampling volume flow in the event of pressure changes
\n\u2022<\/span>\u00a0\u00a0\u00a0No diffuser, no dilution required<\/p>\n

The DFP 3000 can be equipped with three different aerosol generators:
\n\u2022<\/span>\u00a0\u00a0\u00a0For measurement of the fraction separation efficiency with oil:\u00a0PLG 3000<\/b>
\n\u2022<\/span>\u00a0\u00a0\u00a0For burden tests, short burdening times with oil:\u00a0AGF 3000<\/b>
\n\u2022<\/span>\u00a0\u00a0\u00a0For tests with solid particles up to 3 bar:\u00a0RBG 1000 D<\/b><\/p>\n

The largely automated setup of the test sequence together with the clearly defined individual components and the individually adjustable sequence programs of the filter test software FTControl deliver the high reliability of our measurement results.<\/p>\n

All air volume flows and the overpressure in the system are automatically monitored and adjusted. The results are presented in detailed form in tables and diagrams and analyzed. With more than 120 complete filter test systems manufactured and delivered in over 16 different versions, Palas\u00ae<\/sup>is the world-leading manufacturer of filter test systems.<\/p>\n

1.\u00a0Mobile test set-up, easy filter changes thanks to the movable clean gas section:<\/b>\u00a0Thanks to the movable clean gas section, filter housings of different sizes can be used without difficulty<\/p>\n

2.\u00a0Variable aerosol generation<\/b>\u00a0Thanks to the use of different dispersers for DEHS, dusts etc.; shortened measurement times are possible e.g. through increased aerosol concentration<\/p>\n

3.\u00a0Wall flow separator<\/b>\u00a0With drain valve, prevents the transport of separated oil particles on the walls of the duct in the raw gas into the filter housing<\/p>\n

4.\u00a0Light scattering aerosol spectrometer Promo\u00ae<\/sup>\u00a03000 P for clear particle measurements directly under overpressure up to 10 bar<\/b>; the integrated automatic regulation of the sampling volume flow under pressure changes ensures that the measurement conditions are correct<\/p>\n

5.\u00a0Flexible, pressure-resistant aerosol sensors in the welas\u00ae<\/sup>\u00a02xxx P series in raw gas and clean gas for clear particle measurements directly under overpressure up to 10 bar<\/b>; thanks to the use of welas\u00ae<\/sup>\u00a0aerosol sensors, which are fine-tuned to the different aerosol concentrations in the raw gas and clean gas, no dilution systems are needed<\/p>\n
