Ideal For Exhausting Hazardous Vapors

Venturi-style blowers, also known as Air Horns, use the principles of the Venturi effect to vent hazardous vapors and fumes from below-ground sources. The base of the blower is connected to the underground tank or source where the fumes and vapours are present and compressed air or steam is brought into the blower through a nozzle. Its narrow base constricts the compressed air or steam, which increases its velocity as it moves toward the vent at the top of the horn. This decreases the ambient pressure in the horn and creates a partial vacuum, drawing fumes up through the base and out through the vent.
