Filter media made of different formulations require suitable filtration performance monitoring instruments to measure. Palas\u00ae filter media testing instruments excel in filtration efficiency monitoring. Relying on the good reputation of Palas\u00ae in the field of scientific research, Tianjin Key Laboratory of Pulp and Paper from Tianjin University of Science and Technology chose Palas\u00ae MFP 3000 filter media filtration performance test rig. Applied in the research project “Lab\u2011scale design of two layers wood cellulose filter media to maximize life span for intake air filtration”. The Palas \u00ae MFP 3000 has the advantages of modular design and compliance with multi-standard test specifications and also helped the research team to obtain stable detection data in the measurement of single-layer and two-layer filter media.<\/p>\n

Measurement needs of research teams<\/strong><\/p>\n

The Tianjin Key Laboratory of Pulp and Paper responsible for this research project is affiliated to the Pulp and Paper Engineering discipline of Tianjin University of Science and Technology. It is a ministerial-level key laboratory of the former Ministry of Light Industry and the former Light Industry Association. For this project, the sustainability of filtration performance, service life, overall efficiency, initial pressure drop and cost-effectiveness were studied. The Tianjin University of Science and Technology scientific research team selected three types of commercial cellulose and adjusted the ratio of the top layer pulp. Filter media composed of single-layer and two-layer were fabricated and measured, and the effect of cellulose blending on physical properties and filtration performance was analyzed.<\/p>\n

Both the thickness and the air permeability of the two-layer filter media are higher than those of the single-layer media. Therefore, stable monitoring instruments are required to perform the measurement. For this reason, Tianjin University of Science and Technology chose the Palas\u00ae MFP 3000 filter media filtration performance test rig that meets the standard of “ISO 5011 Performance Test of Air Intake Cleaning Devices for Internal Combustion Engines and Compressors”.<\/p>\n

Extensive filter media detection<\/strong><\/p>\n

In the experiment, MFP 3000 conducts a filtration performance comparison test on filter media made of different formulations according to ISO 5011 standard and validated double-layer filter media products made by the new process. It is measured that its performance life has increased by 37% and its dust holding capacity has increased by 34.7%.<\/p>\n

<\/em>The modular design of the Palas\u00ae MFP 3000 is ISO 5011 compliant. Monitoring can also be performed according to EN779, ASHRAE 52.2, DIN 71460-1, ISO TS 11155-1, EN 1822, ISO 29463 and more. At the same time, the following performance indicators can be monitored according to different test filter materials of users:<\/p>\n

    \n
  1. Pressure drop curve<\/li>\n
  2. Initial classification efficiency<\/li>\n
  3. Classification efficiency in load step-by-step loading<\/li>\n
  4. Dust holding capacity<\/li>\n
  5. Gravimetric filtration efficiency<\/li>\n
  6. Most easily permeable particle size (MPPS) and corresponding filtration efficiency.<\/li>\n<\/ol>\n

    MFP 3000 is a modular filter media test rig for fractional efficiency, differential pressure, dust holding capacity and gravimetrical efficiency in suction mode. Version HF is equipped with temperature and humidity control. MFP 3000 has an integrated mass flow controller that it can be used 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 are also recorded automatically during the filter test.<\/p>\n
