EXHAUST VENTURI TYPE AIR BLOWER
Venturi – Style Air Blowers are versatile, provides high volumes of air for numerous cooling and ventilating applications. Air Blowers have no moving parts, operate on compressed air or steam, and: are ideally suited for use in hazardous atmospheric locations.
Air Blowers are used .for either supply or exhaust applications. Typical applications include venting of tanks, towers, and pressure vessels in process plants and refineries, ventilating tank cars, holds, manholes and confined work areas and cooling and drying applications in shipyards, manufacturing plants, and at construction sites. They can move large volumes of air through long runs of duct.
PRINCIPLE OF OPERATION:
Air Blowers operates on the Venturi principle that uses small volumes of high velocity air or steam to accelerate large volumes of low velocity air.
In the blower air or steam enters a concentric manifold chamber surrounding a Veturi throat. A series of orifices located symmetrically around the chamber are positioned to expand the air or steam into the reaction zone downstream of the throat. It is here that the high velocity air or steam imparts its energy to slower moving air and accelerates it which in turn draws more air through the throat into reaction zone. Direction and expansion rate of the accelerated air is controlled by a conical -shaped diffuser
