DFP 3000 Air Filter Test Rig

The newly developed compressed air filter test rig DFP 3000 delivers fully-automated measurements of fraction separation efficiency for compressed air filters under overpressure up to 10 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 Promo® 3000 P, which is equipped with pressure-resistant welas®aerosol sensors for raw gas and clean gas measurements. The system offers the following advantages (among others):
Clear determination of the particle size and concentration directly under overpressure up to 10 bar
Automatic adjustment of the sampling volume flow in the event of pressure changes
No diffuser, no dilution required
The DFP 3000 can be equipped with three different aerosol generators:
For measurement of the fraction separation efficiency with oil: PLG 3000
For burden tests, short burdening times with oil: AGF 3000
For tests with solid particles up to 3 bar: RBG 1000 D
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.
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®is the world-leading manufacturer of filter test systems.
