Palas® Multi-Standard Filtration Performance Test Rig for Air Filter Media

There are many types of common air filters, which can be roughly divided into four categories according to their uses: Engine Intake Filters, Cabin Air Conditioning Filters, General Ventilation System Filters and HEPA/UHEPA Filters. Different types of products have corresponding international standards that require how to complete the testing and rating of product particle filtration performance. These products and their corresponding international standards are:

– Engine Intake Filters：ISO 5011, ISO 19713
– Cabin Air Conditioning Filters：ISO 11155-1, DIN 71460
– General Ventilation System Filters：ISO 16890, ASHRAE 52.2, EN 779 (Expired)
– HEPA/UHEPA Filters：ISO 29463, EN 1822

Only ISO 29463 and EN 1822 have the section part III to describe how to perform the test of particle filtration performance for filter media. The rest standards put forward various test requirements and conditions for filter elements only. Whether it is the incoming inspection needs of filter manufacturers, or the research and development and quality control needs of filter manufacturers, or the demand of research from university researchers are required to follow the test methods and conditions requested in the above filter standard and complete the filtration performance test of the filter material to grasp the actual filtration performance of the product. These standard test items and test conditions are shown in the following figure:

Comparison of relevant standard requirements and test items

In these standard tests, there are three key points to pay attention to respectively:

1. The filtration efficiency that most standards focus on is the fractional efficiency, that is, the efficiency based on the number concentration of particles at each particle size.
2. Under different standards, the particle size ranges of the particles of interest are significantly different.
3. Dust loading test is a very important test item in most standards.

Palas® MFP filter media filtration performance test rig series support many of the above test standards which can provide up to five common filtration performance tests in the range of 5cm/s – 100cm/s including pressure drop curve, initial fractional efficiency, fractional efficiency during dust loading, dust holding capacity and gravimetric filtration efficiency. At the same time, relevant tests can be completed based on different standards and a complete report can be provided. At present, many university scientific research teams and industry manufacturers have completed product development and quality control with the help of Palas® filter media filtration performance test rig.

The Trust of University Research Teams and Industry Manufacturers

The College of Physics from Qingdao University selected the Palas® MFP 3000 G filter media filtration performance test rig for its research project. It is very important for university research teams to test whether the instruments can meet multiple monitoring standards and provide accurate and stable monitoring results. MFP 3000 G series, customized according to ISO 16890, ASHRAE 52.2 and EN 779 standards, provide test functions such as dust loading, grading and filtration efficiency, and pressure loss curve required in the standard. And the MFP 3000 G is equipped with a static neutralization device in the air intake. It is used to neutralize the charged amount of aerosol particles to ensure that the generated aerosol particles will be evenly distributed in the test channel. The specially designed aerosol inlet supports the simultaneous connection of three aerosol generators, thereby improving the automation of the software testing process and reducing personnel operations. At the same time, the structure is simple, and the replacement of the aerosol generator and the cleaning of the test channel can be completed more easily.
