Darkroom
Exhaust Fans and Louvers
With all of the toxic chemicals and fumes which are released during film processing,
the need for adequate ventilation in darkroom work areas cannot be over emphasized.
Improperly ventilated space can be harmful to the health of workers. Now available
is our "Air-No-Lite" 100% light tight darkroom exhaust fans and louvers
which insure healthy ventilation continuously.
Each fan is one piece molded body and five sections molded louver. Different sizes of fresh air supply louvers are available. Each size is designed to supply just the right amount of air to a particular model exhaust fan. Exhaust fans work best in a darkroom that is equipped with fresh air supply louvers or some other kind of air supply. If there is no air supply to the darkroom, the fan will be working against a vacuum and can do nothing.
Electrical: 110 V AC, 60 Hz. 3-wire grounded cord.
