Need more fresh air as you paint? Basement becoming mildewed and unpleasant? Want stronger, healthier plants and clearer, cleaner air as you tend them?<br/><br/> OMTech's inline duct fan keeps your surroundings fresh as a daisy. Designed for 4" ducts, this ventilation and exhaust fan eliminates odors and keeps your environment habitable thanks to its 2500 rpm rotational speed and 200 cfm airflow.

The galvanized steel casing, PVC cover, and PA66 blades offer durable service and corrosion-proof performance wherever needed, from paint booths to high-humidity environments like bathrooms, plant growing tents, and laser engraving workshops.
