Product overview
The JF-HF-KE series high efficiency knife edge filters are specially designed to be used with gel seal guides, allowing you to reuse the gel seal and reduce costs. The unique knife sealing blade, thanks to its precise alignment with the mounting frame, ensures high tightness, no risk of leakage and stable operation over a long service life.
Applications
Most commonly used in Class A/B and higher laminar air systems and as horizontal high efficiency filters, particularly in filter applications requiring PAO leak testing.
