[vc_row][vc_column][vc_column_text]With the new MFP 3000 HF, it is now also possible to set the relative humidity from 10 to 80 % or the temperature from -10 to 50 \u00b0C. The inflow velocity has been extended as compared with standard models to a range of 4 cm\/s \u2013 2 m\/s.<\/b><\/p>\n

The MFP 3000 HF serves to determine\u00a0filter parameters under realistic air conditions<\/b>, such as<\/p>\n

\u2022<\/span>\u00a0\u00a0\u00a0\u00a0the differential pressure of the filter medium at different inflow velocities
\n\u2022<\/span>\u00a0\u00a0\u00a0\u00a0the fractional efficiency and the differential pressure at a defined air volume flow
\n\u2022<\/span>\u00a0\u00a0\u00a0\u00a0the differential pressure and the fractional efficiency at a defined air volume flow
\n\u2022<\/span>\u00a0\u00a0\u00a0\u00a0the dust holding capacity and the associated gravimetric efficiency at a prescribed air volume flow and increase in differential pressure.<\/p>\n

 <\/p>\n

Air conditioning<\/h3>\n

With the MFP 3000 HF, a\u00a0new test rig concept<\/b>\u00a0has been implemented for this purpose, which provides for particularly stable data on air conditioning. This includes an isothermal measuring chain to prevent evaporation and condensation effects of particles in the test channel, as well as during sampling and particle measurement. For this reason, the MFP 3000 HF was equipped with active cooling and heating elements, which allows the air conditioning to be almost independent of the climatic conditions in the lab.<\/p>\n

<\/h3>\n

Aerosol generation<\/h3>\n

The modular system of the MFP 3000 series enables the use of different test aerosols like salt particles, DEHS particles and test dusts like ISO A2 Fine. Aerosol generation is characterized by extremely high consistency in the aerosol concentration and the particle size distribution emitted.<\/p>\n

<\/h3>\n

Aerosol measurement from 5 nm to 40 \u00b5m<\/h3>\n

For the first time, the U-SMPS 2100 particle sizer has been integrated into the MFP 3000 series for measurement of nanoparticles in the range from 5 nm to 1 \u00b5m. The MFP 3000 HF comes equipped with automatic manual switching between the raw gas and pure gas measurement points.
\nThe light scattering spectrometer Promo\u00ae<\/sup>\u00a03000 HP performs clear particle measurements in the range from 200 nm to 40 \u00b5m and depending on the choice of sensor also in high concentrations up to 5000 mg\/m3<\/sup>\u00a0(SAE Fine) or low concentrations for determination of the initial fraction separation efficiency.<\/p>\n

<\/h3>\n

Automation<\/h3>\n

The MFP 3000 has an integrated mass flow controller to control the volume flow. The volume flow rates are automatically monitored and controlled by the FTControl filter test software. The data from the integrated sensors \u2013 such as the volume flow, temperature, relative humidity and differential pressure at the filter \u2013 are also recorded automatically during the filter test.<\/p>\n

 <\/p>\n

Sampling and layout<\/h3>\n

The vertical layout allows even large particles (up to 40 \u00b5m) to make their way onto the filter medium. On the raw and clean gas side, isokinetic sampling probes are provided for the raw and clean gas sensor.<\/p>\n
