Portable ventilation for confined spaces

The VEVOR SHT-40 is a 16 inch axial blower designed to move air through a 32.8 ft flexible duct. It suits contractors, facility managers and DIY users who need to exhaust fumes, dust or heat from basements, workshops or warehouses where permanent ducting is impractical.

Two-speed operation and IP44 protection

On the low setting the motor draws 542W and delivers 4475 CFM; on high it draws 695W for 5175 CFM. The housing is built from 0.8 mm carbon steel with an aluminum impeller and carries an IP44 rating, so splashing water and solid particles larger than 1 mm will not interrupt operation.

Sustained airflow with overheat safeguard

Overheat protection cuts power if internal temperatures exceed safe limits, allowing the fan to run continuously on either speed without thermal shutdown. The 33 ft duct maintains rated airflow over its full length, so the unit can stay outside the hazardous area while pulling contaminated air out through the entire run.

Questions about this item

How do I set up the 16 inch Portable Ventilator with the 32.8 ft duct hose for a basement?

Place the unit on a stable surface near a 110V 60Hz outlet. Unroll the flexible duct fully to avoid kinks, attach it securely to the housing outlet, and direct the other end outside. Select high or low speed depending on airflow needed.

What maintenance will the carbon steel housing and aluminum impeller need over time?

Periodically wipe the 0.8 mm carbon steel housing and aluminum impeller blades to remove dust buildup. Check the duct for tears or blockages. Ensure the overheat protection remains unobstructed by keeping intake vents clear of debris.

How long can I run the blower at 695 W high speed before the overheat protection activates?

The overheat protection engages automatically when internal temperatures exceed safe limits during sustained high-speed operation. Allow the unit to cool before restarting. Continuous runtime varies with ambient temperature and duct configuration.
