The use of HS PRVs to vent heat and smokes has these specific advantages: * It is not dependent on air temperature differential or wind direction and velocity to create air movement. * It does not rely on heat itself to activate the system. Smoke detectors and water-flow devices also may be utilized. * It provides for normal ventilation needs of the building as well as for emergency use as a vital component of the fire protection system. * There is usually a substantial cost saving in the purchase and installation of the dual purpose system. * Maintenance cost for building and equipment is frequently reduced. * The system can be effectively used in multi stories and below grade building areas. * Reliability of operations is assured because powered ventilators are in daily use and receive regular inspection and maintenance. The unique Canada Blower Type HS power roof ventilators provide a solution for emergency heat and smoke venting that is dependable under the most extreme circumstances. All critical components of Canada Blower HS PRV that exposed to the air-stream are ferrous construc-tion to withstand high temperature c onditions . These heavy gauge materials prevent warping of fan parts and malfunc-tion at high temperatures. This also insures years of trouble-free service in normal daily operation of the PRV fan. The wind shroud is made of galvanized steel; an exterior finish coat of epoxy can be specified. Painted parts are coated with epoxy to provide a protective coating rated excellent for hardness, impact resistance, adhesion and chemical resistance.
