Exhaust Fans

Exhaust fans remove heat, moisture, fumes and dust from a building rather than circulating air within it, which makes them the primary ventilation equipment in factories, commercial kitchens, livestock housing and process areas. Mounting position — wall, roof, duct or window — is usually dictated by the building, and it in turn dictates the fan type.

Sizing an Exhaust Fan & category detail

Sizing an Exhaust Fan

Work from air changes per hour for the room volume, not from fan diameter. A workshop needs 6 to 10, a commercial kitchen 15 to 30, a livestock shed considerably more in summer. Then confirm the fan can achieve that against the actual resistance of louvres, filters and ducting. For flammable or corrosive atmospheres, only a certified flameproof motor with a non-sparking impeller is acceptable.
