The portable ventilation fan is used along with flexible ventilation ducts to circulate fresh air or remove unwanted air, and it may
also be used to maintain a suitable working temperature. Ducts connect to the ventilator through a strap system. It can be usedapart from ducts for the same purposes. The steel housing protects the motor and other interior parts, ensuring safe operation.
The vent fan can safely be used for air supply and exhaust in deep working spaces where ceiling fans are non applicable,
especially for cable maintenance, ship building, municipal underground engineering, and chemical or industrial factories.
The ventilator can also be used for drying.
