Introduction of Air Filter Test

Air filters are widely used in clean room or workshops such as food, medicine and semiconductor electronics factories, HVAC systems such as hospitals, office and residences buildings, electrical appliances such as purifiers and vacuum cleaners, dust removal in industrial plants and other occasions, to provide clean air required for specific occasions through filtering.

The quality of the air filter

determines the grade of the cleanliness

If the filtering efficiency of the air filter is unqualified, fine dust and impurities will enter in large quantities, which will seriously affect the overall effect of air filtering.
If the resistance (pressure differential) of the air filter is too high, it will increase the energy consumption or reduce the inlet and outlet air volume.
If the dust capacity of the air filter is not enough, the service life of the filter may not be long.

For the test of air filter, specified aerosol or fine particles are used to test the filter efficiency and resistance for different particle sizes under a certain air volume. It can also evaluate the resistance variation under different air volume, and the resistance variation under different dust capacity, so as to evaluate the service life of the filter.

SC-13011 Small Filter Tester

Air Filter Tester Types & Scenatios - How To Pick

Different filters are required for different occasions and purposes. Filters for different purposes shall meet different standards. Each standard has provisions on the test indicators, test methods, and even test equipment.

Filters for HVAC and Air Purifier

These filters are designed and manufactured according to ISO 16890, ISO 29464, ASHRAE 52.2, etc., and are used in office buildings, gyms, stations, airports, homes and other occasions. The indicators to be tested include filter efficiency, dust capacity, resistance (pressure differential), etc.

SC-7099 EPA & HEPA Filters Quality Control Test System is recommended if only fractional efficiency, resistance (pressure differential) and pressure differential as a function of the air flow rate need to be tested.

SC-16890 is recommended if the gravimetric efficiency (arrestance) and dust capacity also need to be tested.

Filters for Clean Room

These filters are designed and manufactured according to EN 1822-1, ISO 29463, etc., and are used in medicine, food, operating room, library, electronic chip and other occasions. Overall efficiency, local efficiency, MPPS efficiency and resistance (pressure differential) need to be tested. The HEPA filters of H13, H14 and ULPA filters of U15, U16 and U17 classes also need to be detect the leakage one by one.

SC-L8023 series test system and SC-L8025 test system are recommended for these filters.

Filters for Cabins

These filters are designed and manufactured according to ISO/TS 11,155, DIN 71,460 , etc.

Fractional efficiency, pressure differential as a function of the air flow rate and dust capacity shall be tested.

SC-11155 Cabin Air Filter Test System is recommended for these filters.

Filters for Vacuum cleaner

These filters are designed and manufactured according to IEC/EN 60335-2-69, ASTM F1977, IEC/ASTM 62885-7, etc. Some standards specifies the appearance and cleaning capacity. IEC/EN 60,335-2-69 also specifies the filtration efficiency of filter media, filter elements and the whole machine.

SC-13011 is recommended for testing these filter media and filter elements.

If you need to test the whole vacuum cleaner, please contact us for customization.

Filters for Reduce Emissions

and Protect Environment

It mainly refers to filters used to control exhaust emissions such as cement plants, power plants, steel plants, garbage incineration, iron smelting, automobile and other occasions. As countries realize the importance of environmental protection, the efficiency of these filters is required to be much higher, upgrade from F class to HEPA class. For these products, different testing equipment can be selected according to the indicators to be tested.

With the highest cost performance, SC-7099 is recommended.

Customer Cases

Some field applications and filter test system customization cases.

Test of filter with class F9 and length of 1.2 meters

This customer is engaged in the field of new energy battery manufacturing, and uses a large number of filters of different class with unconventional sizes.
According to the test of HVAC general ventilation filters, the filter length and width are not more than 700mm. According to the HEPA test, the efficiency of the test rig is higher than that of the F-class filter.
Our engineer carried out many experiments. Finally, the class F9 filter with a length of 1.2m could be tested. In order to make it more convenient for customers to use, we have also added tips for scrapping and replacing consumables (filters).
At present, the equipment has been delivered to the customer for use and has passed the customer acceptance.

Test of Filter Cartridge

This customer is engaged in the field of air filters, the products including filter cartridge, plane filter, V-bank filter, and filter bag. It is a difficult problem that all these types of filters are tested in the same equipment, especially the test of filter cartridge. After receiving the customer's customized demand, we started with product design and determined the final plan through repeated calculation.
For more than three months, SC-7099-3500 was successfully delivered, from accessories to assembly and repeated testing. Four types of filters with different sizes are tested on the same testing equipment, which saves a lot of testing costs for customers.
The test results of the product are basically consistent with the test results sent by the customer to the testing agency.

We provide

After many adjustments of the hardware and software, leakage detection by scanning method of the V-type filter finally realized on SC-L8023. One year later, our engineers took two days to complete the upgrade, and the test speed was increased by 3 times.
