V bank HEPA filter

Large Filtration Area
The unique V-shaped design enables it to provide a larger effective filtration area than ordinary panel filters within a limited installation space, thereby reducing air flow resistance and extending service life.
High Dust Holding Capacity
The increased filtration area means that more dust particles can be accommodated, reducing the frequency of replacement and lowering maintenance costs..
Structural Stability
The filter material is usually made of high-strength PP filter paper or glass fiber and is supported by a sturdy metal or plastic frame to ensure it is not prone to deformation at large air volumes.
Wide Range Of Efficiency
V cell filters cover multiple efficiency grades from medium efficiency (F5-F9) to high efficiency (H10-H14), offering great flexibility in application.

HEPA Filter Testing: Making Sure They Work Great

Testing HEPA Filters is a big part of our job to make sure they can achieve great air purification. We put each filter through a bunch of tests to make sure it captures particles, doesn’t leak, and doesn’t slow down your air too much. We do this to make sure every filter meets our high standards and works great in lots of different places.

HEPA Testing - test

At our facility, every HEPA filter undergoes rigorous DOP/PAO testing to guarantee superior performance. We challenge each filter with an aerosol of fine particles—such as Dioctyl Phthalate (DOP) or Polyalphaolefin (PAO)—to measure its capture efficiency. This method ensures that our filters not only meet but often exceed industry standards for particle retention.

Air flow and pressure drop test

Perfecting the balance between filtration and airflow is what sets our HEPA filters apart. While capturing particles effectively is essential, maintaining strong airflow is equally critical. We meticulously test each filter’s resistance to ensure it delivers optimal air movement without compromising filtration performance.

Leak Testing

Every HEPA filter we produce undergoes a rigorous leak test to ensure complete integrity. We meticulously inspect for any defects in the filter media and seals to guarantee there are no leaks. This critical step verifies that each filter performs reliably, providing consistently clean and safe air quality.
