Darkroom exhaust fan
With all of the harmful chemicals and gases emitted during darkroom techniques, the need of proper ventilation in darkroom work environments cannot be over emphasised. Poorly ventilated spaces might be hazardous to workers' health.
Each fan is made up of a one-piece molded body and a five-section molded louver. Fresh air supply louvers come in a variety of sizes. Exhaust fans perform well in a darkroom with fresh air supply louvers or another type of air supply. If there is no air supply to the darkroom, the fan will be working against a vacuum and will be rendered ineffective. Each size is intended to provide the exact amount of air required by a specific model exhaust fan.
