NHFF – HEPA Filtered Fan

G4 within the body of NHFF ensures that the air supplied to closed areas is purified from dust, odor and foreign substances with its activated carbon and H13 HEPA filter. Thanks to the by-pass damper, the air can only be passed through the G4 filter. In this way, the life of the HEPA filter is extended.
