Features of Gel Sealing ULPA Air Filter
PU gel seal
Absorbs vibration during equipment operation (such as fan vibration) to avoid micro leakage caused by fatigue of traditional rubber gaskets.
Gap filling
Automatically fills the small unevenness of the frame and filter frame to achieve zero gap sealing.
Chemical protection
Resist the erosion of clean room disinfectants (such as hydrogen peroxide, sodium hypochlorite) and extend filter life.
Biosafety laboratory: The liquid tank seal eliminates edge leakage and meets the high sealing standards of biosafety cabinets and laboratory exhaust systems.
Pharmaceutical and sterile production: Gel sealing mini pleated ULPA air filter meets GMP Class A cleanliness requirements and is used in injection filling lines and vaccine production.
Operating room and ICU: Control the concentration of bacteria and viruses to prevent postoperative infection.
Negative pressure isolation ward: Cooperate with HVAC system to prevent the spread of infectious diseases.
Optical/precision instrument manufacturing: Maintain a dust-free environment to avoid lens or sensor contamination.
