Description
Canarm U20-4HD Portable Confined Space Blower Fan (6,850 CFM, 20in)
The Canarm U20-4HD Portable Confined Space Blower Fan is a heavy-duty industrial ventilation system designed for confined space entry, construction sites, and hazardous air removal applications. Delivering up to 6,850 CFM (cubic feet per minute), this 20-inch blower provides strong and consistent airflow to remove fumes, dust, heat, and contaminated air while supplying fresh air into enclosed or poorly ventilated environments.
Built with a rugged powder-coated steel housing and an explosion-proof industrial motor, the U20-4HD is engineered for safe operation in demanding and safety-critical environments. Its larger 20-inch design enhances airflow coverage and efficiency, making it suitable for larger confined spaces such as tunnels, tanks, vaults, and underground work zones.
This model is widely used in construction, industrial maintenance, utility operations, and emergency response applications where reliable ventilation and worker safety compliance are required.
