The high volume PuriCel l filter is suitable for higher volume applications compared to the same type of filter with the standard volume type. It can be used flexibly and save the cost of higher surface wind speed (up to 2.5m/s, with little increase in initial pressure loss).
cleanroom high-efficiency HEPA filter with baffle (high air volume/standard air volume)
Box type with baffle cleanroom HEPA filter, high air volume expansion filter surface, compact structure, lightweight, is widely used in a variety of industrial, commercial, civil building ventilation system high-efficiency filtration section.
The high air volume PuriCel l high-efficiency HEPA filter is suitable for higher volume applications compared to the same type of filter with the standard air volume type. It can be used flexibly and save the cost of higher surface wind speed (up to 2.5m/s, with little increase in initial pressure loss).
Compared with the standard air volume cleanroom HEPA filter, under the same air volume, low resistance, less energy consumption, and long service life.

Leak detection test - To ensure that there are no leaks on the high-efficiency HEPA filter, it must be scanned for testing. Cleanroom HEPA filters that have passed the total leakage test may still have some leakage points, which can be found by scanning the test, and these leak points can be repaired before leaving the factory, using a versatile ethanol aerosol that does not remain on the high-efficiency filter media to test.
Wedge fold design to prevent filter material high-efficiency filter media damage
PuriCel I box type with baffle high-efficiency HEPA filter, HEPA filter media double fold, filter material bending two indentations can make the HEPA filter media at the end of the diaphragm to form a wedge box fold, thereby preventing filter material damage, extend the cleanroom HEPA filter life. The corrugated aluminum baffle keeps the distance between the pleats precisely, and the edge of the baffle is rolled to prevent damage to the filter material and maximize the use of the HEPA filter media with minimal resistance.
Ultrafine glass fiber HEPA filter paper, water resistant, flame retardant selected high-quality ultrafine glass fiberHEPA filter media, high density. The filter material is waterproof and flame-retardant.
100% leak free
The polyurethane glue completely seals the filter material in the frame, penetrates into the HEPA filter media to prevent the gap, and completely seals the filter material edge and partition and other channels that may occur side leakage.

Advantages of choosing high air volume type:
l Fewer filters required
l Small installation space required
l Low replacement frequency, saving replacement time and labor
l The life of the high air volume type is about twice that of the standard air volume type (when running at 1000CFM)
l Rated initial resistance (248 Pa)
l Under the same air volume, save operating electricity costs corresponding to the rated air volume

Professional recommendation
The cleanliness of the filtered air is mainly determined by the filter at the end of the filtration system. Installing a qualified, high-quality primary/intermediate effect filter before the end of the high efficiency HEPA filter can extend the life of the high efficiency HEPA filter and achieve the purpose of reducing the replacement frequency and operating costs.
