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 MFP 3000 operates in suction mode. This ensures a particularly uniform formation of the dust cake even at high inflow speeds.
With the aid of the light scattering spectrometer Promo® 3000, clear and reliable determination of the aerosol concentration and the particle size and therefore a clear determination of the fraction separation efficiency can be ensured. In addition, use of the welas® digital 3000 or Promo® 3000 with two sensors for virtually simultaneous particle measurement offers the following advantages:
Fully-automatic measurement of fraction separation efficiency
