Product Information:
G4500 with two Promo® aerosol spectrometers for simultaneous determination of fraction separation efficiency
The MFP filter test rig is a modular filter testing system for flat filter media and small mini-filters. This enables you to determine the pressure loss curve on the medium without a dust coating, fraction separation efficiency, or burden and fraction separation efficiency during application of the burden and the gravimetric separation efficiency within shortest times – reliably and therefore cost-effectively. The G4500 operates in suction mode. This ensures a particularly uniform formation of the dust cake even at high inflow speeds. With the new FTControl test rig software of the G4500, the aerosol spectrometer Promo®1000/2000 is used for clear and reliable determination of the aerosol concentration and particle size and therefore clear determination of the fraction separation efficiency.The use of one aerosol spectrometer Promo® 1000/2000 in raw gas and one in clean gas within simultaneous operation offers the following advantages: Fully-automatic simultaneous measurement of fraction separation efficiency Faster determination of the beginning fraction separation efficiency because of bisection of the testing time for the fraction seperation efficiency. Higher temporal resolution for the measurement of fraction seperation efficiency during loading. Using the testing system for very high and very low aerosol concentrations. The largely automated setup of the test sequence in conjunction with the clearly defined individual components and the individually adjustable sequence programs of the filter test software FTControl combine to deliver the high reliability of our measurement results.
Our quality in detail
Structure:
1. Variable aerosol generation Thanks to the use of different dispersers for dusts, KCl/NaCl, DEHS etc.; shortened measurement times are possible e.g. through increased dust concentration
2. Corona discharge (optional): Adjustable ion stream for different mass flows. Mixed air, adjustable for inflow speeds from 0.05 to 1 m/s. Optional: Transient inflow.
3. Light scattering spectrometer Promo® 1000/2000 for clear particle measurements in high concentrations of up to 5000 mg/m3 (SAE Fine) and low concentrations for the determination of the initial fraction separation efficiency
4. Mobile pneumatic filter holder for fast removal and loading of the test rig.
5. Gravimetric filter holder for simple and fast evaluation of the gravimetric separation efficiency.
6. Raw gas sensor
7. Clean gas sensor
