Allegro Venturi Blowers work by moving air in work sites such as power plants, utility plants, refineries, shipyards, paper and pulp plants as well as the steel and marine industry and manhole operations. Basically anywhere fumes may be poisonous, explosive or hazardous a Venturi Blower works it best.
Venturi Blower Large
The Venturi Blowers from Allegro are a perfect solution to moving air in refineries, utility and power plants, shipyards, paper and pulp plants, the marine and steel industry and confined space manhole operations.
Compressed air or saturated steam is the power source for our Venturi Blower line. Small volumes of high velocity air (from a compressed air source) run through the casting and out of the nozzle jets, creating a venturi action or pulling action that creates large volumes of air through the Venturi blower and out the air diffuser.
A 1/2" hose with a "crows foot" connection is recommended from your air supply source to the side inlet connection. Operate this Venturi Blower on air or steam lines limited to 140 psi.
