Pneumatic Powered Fans

Pneumatic confined space blowers are designed for use in confined or enclosed spaces, such as tanks, pipelines, and manholes. These blowers are designed to provide ventilation and air movement in areas where natural air flow is limited or absent, and where hazardous gases or fumes may accumulate. By using compressed air to power these fans, the possibility of sparking a hazardous gas is greatly reduced. 

Pneumatic air horns, or venturi blowers, are a perfect solution to moving air in refineries, utility and power plants, shipyards, paper and pulp plants, the marine and steel industry and manhole operations.  They are used to remove poisonous, explosive or hazardous fumes from confined spaces such as process towers, tanks, and large pipes. You can cool workers in elevated temperature conditions, or cool heavy equipment that may be in danger of overheating with a blast of directed air.

Rugged, cast aluminum housing and fan blades make these fans ideal for hazardous locations and demanding ventilation projects. The design uses action-reaction principles as compressed air is discharged through nozzles located at the tip of the fan blade providing extremely efficient, high-volume, low-maintenance air movers
