VHP head cover fumigation transfer window

The VHP head cover fumigation transfer window, a commonly used sterilization equipment in P3 and P4 workshops, is primarily designed for the transfer of head covers and protective clothing between low and high contamination probability areas after use. The dual doors feature interlocking mechanisms and inflatable seals, while the equipment is connected to the wall using a biological sealing method. With its VHP sterilization function, it effectively reduces the risk of biological contamination during the transfer of head covers.

performance metrics
