MFP Nano plus 4000 Filter Test Stand

Palas ® ofMFP Nano plus 4000 Filter Test StandIt has been validated multiple times in practical applications of development and quality control around the world.

MFP Nano plus 4000 Filter Test StandSpecially designed to accurately determine the separation efficiency of HEPA and ULPA filter media according to DIN EN 1822-3 and ISO 29463-3 standards.

This device is a modern and powerful nanoparticle measurement device that performs particle size measurement and numerical analysis in the range of 5 nm to 1 µ m in the form of a U-SMPS

Real time measurement of separation efficiency of specific sizes in raw gas and clean gas using MFP Nanoplus 4000 and UF-CPC condensation particle counter.

The real-time measurement of the separation efficiency of MFP Nanoplus 4000 fractions has the following special advantages:

By measuring the particle concentration in the raw gas and clean gas, the measurement time for determining the fraction separation efficiency can be halved.
Combining two versions of UF-CPC, the highest measured concentration of UF-CPC in the feed gas can reach 2000000 particles/cubic centimeter (single counting mode), while the highest counting rate of UF-CPC 50 at low concentrations of clean gas corresponds to a dilution factor of 1:200. Therefore, conventional aerosol dilution is no longer required.

With the help of the universal aerosol generator UGF 2000, DEHS or salt (NaCl/KCl) can be used to produce aerosol distributions that match the MMPS range.

The highly automated setup of test sequences, as well as the individually adjustable programs of clearly defined individual components and filter testing software FTControl, collectively provide highly reliable measurement results.

The MFP filter test bench is a modular filter testing system used for flat filter media and small micro filters. It is possible to determine the pressure loss curve, fraction separation efficiency or load in a very short period of time, which is both reliable and cost-effective.

Our quality details

1. Use UGF 2000 to generate various aerosols for KCl/NaCl or DEHS. Integrated Nafion drying system. Adjust the smoke volume flow rate separately through a mass flow controller.

2. Aerosol neutralization: Kr-85-370 power supply or soft X-ray charger XRC 370 corona discharge (optional): Adjustable ion flow suitable for different mass flow rates. Mixed air, adjustable inflow speed of 1.5 to 40 centimeters per second. Monitoring and control are achieved through a quality flow controller.

3. A movable pneumatic filter bracket for quick disassembly and loading of test benches with integrated DEMC 2000 (differential transfer classifier). The DEMC 2000 (Differential Electromobility Classifier) included in U-SMPS is used to classify the particle size of polydisperse aerosols generated by UGF 2000. The downstream of DEMC 2000 only contains monodisperse particles. DEMC 2000 automatic adjustment related particle size control unit.

4. Use UF-CPC 200 for high concentration raw gas measurement. In order to measure the number of particles in the raw gas, the UF-CPC 200 condensation particle counter is used in single counting mode to count up to 2000000 particles per cubic centimeter. This means that there is no need for dilution systems in high concentration raw gas measurements. No need for lengthy or complex cleaning of the system.

5. Use UF-CPC 50 to measure the numerical distribution of clean gases at low concentrations
The "full flow" UF-CPC 50 has been optimized for low particle concentrations in clean gases (single counting mode, maximum 10000 particles/cm3).
In the "full flow" particle measurement of UF-CPC, a comprehensive analysis of the entire sampling volume flow rate was conducted. This means that high counting rates can be achieved at low particle concentrations in clean gases.

Palas ® The filter testing software FTControl controls the U-SMPS and evaluates the data.

Adjust aerosol distribution to MPPS range
By adjusting the solution concentration appropriately, the generated particle size distribution can be matched with the relevant MPPS range in MFP Nano+4000.

Clearly demonstrate the separation efficiency of the filter medium throughout the entire measurement range.
Accurately determine the MPPS range.
The highest measurement reproducibility and repeatability highlight small differences in separation efficiency.
Optimized aerosol application, reducing the measurement time for each separation efficiency measurement to as short as two minutes.
Simple comparison of separation efficiency curves and calculation of average values

Automation:

MFP Nano+4000 integrated mass flow controller for controlling volumetric flow rate; Automatic monitoring and control can be achieved through FTControl filter testing software.

During the filter testing period, sensor data such as the volume flow rate and pressure difference of the filter will also be automatically recorded.

Verify if the sampling in raw gas and clean gas is qualified: During the initial training process, the measurement compliance verification of unfiltered raw gas and clean gas will be demonstrated.

By using MFP Nano+4000, it is possible to measure fraction separation efficiency within the MPPS range and throughout the entire measurement range. In addition, clearly determine the relevant pressure loss of the medium at the relevant inflow velocity.

Advantages:

Real time measurement of fraction separation efficiency for particles above 10 nm
By measuring the particle concentration in the raw gas and clean gas, the time required to determine the separation efficiency of fractions can be reduced by half.
No need for dilution!
Combining two versions of UF-CPC, the highest measured concentration of UF-CPC in raw gas can reach 2000000 particles/cubic centimeter (single counting mode), while the highest counting rate of UF-CPC 50 in low concentration clean gas corresponds to a dilution factor of 1:200.
