12" Axial AC Plastic Blower

Allegro 12" Axial AC Industrial Plastic Blower (9539-12)

The Allegro 9539-12 is a lightweight, portable, and durable 12" axial blower built for ventilating large confined spaces such as paper mills, tank purging, and utility sites. Its single-phase 1 HP motor moves up to 2,180 CFM in free air, and the blower delivers both positive and negative airflow, so you can supply fresh air or exhaust contaminated air. It can also be used as an inline booster blower to extend airflow over longer duct runs.

The housing is molded from polyethylene that is lightweight and resistant to corrosion, UV, and chemicals, in a high-visibility "safety orange." A bottom enclosure protects the electrical components, and the built-in On/Off switch, molded carry handle, and stackable design make it easy to move, store, and deploy. It runs super quiet, and it's CSA certified to CSA Standard C22.2 No. 113.
