General Equipment Co.’s EP17 Positive Pressure Ventilator borrows heavily from the highly successful positive pressure technology utilized by fire departments for smoke removal. The electric-powered EP17 is the first positive pressure ventilator designed specifically for industrial-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 or confined area. 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 1 1/2-horsepower, 115 VAC electric motor, the EP17 produces an airflow rate of more than 5,000 CFM (cubic feet per minute) with a 4 1/2-inch static capacity. This unit operates from a standard 15-ampere circuit. The GP21, a gas-powered unit, is also available from General Equipment.
The EP17 features a welded, heavy-gauge tubular structure that quickly adjusts to effectively direct the air stream.
