Filter Media Tester DFP 3000

DFP 3000 Compressed 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.

Descriptions
 Mobile test set-up, easy filter changes thanks to the movable clean gas section: Thanks to the movable clean gas section, filter housings of different sizes can be used without difficulty
2. Variable aerosol generation Thanks to the use of different dispersers for DEHS, dusts etc.; shortened measurement times are possible e.g. through increased aerosol concentration
3. Wall flow separator With drain valve, prevents the transport of separated oil particles on the walls of the duct in the raw gas into the filter housing
4. Light scattering aerosol spectrometer Promo® 3000 P for clear particle measurements directly under overpressure up to 10 bar; the integrated automatic regulation of the sampling volume flow under pressure changes ensures that the measurement conditions are correct
5. Flexible, pressure-resistant aerosol sensors in the welas® 2xxx P series in raw gas and clean gas for clear particle measurements directly under overpressure up to 10 bar; thanks to the use of welas® aerosol sensors, which are fine-tuned to the different aerosol concentrations in the raw gas and clean gas, no dilution systems are needed
Aerosol generation
The DFP 3000 can be equipped with three different aerosol generators:
For measurement of the fraction separation efficiency with oil: PLG 3000
The PLG 3000 is used for measurement of the fraction separation efficiency and for burdening with oil aerosols. The oil quantity can be adjusted via the volume flow of the disperser between values of approximately 0.2 and 12 g/h.
For burden tests, short burdening times with oil: AGF 3000
