GP21 Non-Hazardous Location Positive Pressure Ventilator
Available from General Equipment Co
General Equipment Company’s GP21 Positive Pressure Ventilator borrows heavily from the highly successful positive pressure technology utilized by fire departments for smoke removal. The gas-powered GP21 is the first positive pressure ventilator designed specifically for construction-related applications.
Positive pressure technology involves the production of a high volume of air that is directed through an opening and into a job site. The high-static pressure capabilities of the unit’s propellers create a pressure differential that channels the airstream through an available exit and into the atmosphere. Hazardous dusts, fumes and ambient temperature extremes, found in many construction-related activities, can be effectively minimized or eliminated using this method. Positive pressure ventilators can dramatically increase job site productivity and simplify compliance with OSHA atmospheric contamination regulations.
Powered by a 5-1/2 horsepower Honda gasoline engine, the model GP21 produces an airflow rate of 11,000 CFM (cubic feet per minute) with a static capacity of 5 inches or more. An electric powered model (EP17) is also available.
The GP21 features a welded, heavy-gauge tubular structure that quickly adjusts to effectively direct the air stream.
