Our Maxx Air confined space blower fan provides directional airflow in limited access areas such as a basement, crawl space, or attic. The 20 ft. flexible polyvinyl hose attaches to the utility fan's flared housing via cinch strap for a secure and easy setup, pushing fresh air into a space or exhausting air outwards (even off the ground using the pre-installed hanger rings on the hose) to create a safer working environment. Utilize this portable fan's heavy duty carry handle to transport it to your job, and set it down on it's positioning legs with thick rubber feet designed to minimize noise and reduce vibration. This axial hose fan is available as a fan/hose combo (HVHF 12COMBO), or can be purchased separately as the fan only (HVHF 12FAN), or hose only (HVHF 12HOSE).
