Premier's "Air-No-Lite", 100% Light Tight, Darkroom Exhaust Fans and Louvers insure healthy ventilation quietly, efficiently and effectively.
This fan, with its one-piece, molded body with five-section molded louvers, is just one of two required pieces for proper ventilation. To ensure a fresh, circulating air supply, the fan must be used in tandem with item #121212 Premier 12x12 Darkroom Louvers (L-1212). If there is no fresh air supply, the exhaust fan is working against a vacuum and is not effective.
The fan has an unrestricted flow rate of 400 CFM.
