OLEG SYSTEMS

Emergency smoke exhaust systems are designed to remove smoke and heat from buildings in the event of a fire. These systems play a crucial role in increasing occupant safety and allowing rescue personnel to safely enter burning buildings. Twin City Fan offers a full line of smoke and heat fans capable of withstanding a minimum temperature of 500°F for four hours or 1,000°F for 15 minutes. Our inline smoke and heat fans are also available in a vertical roof mount configuration featuring a discharge cap with butterfly dampers and an optional fusible link designed to stay open in the event of a fire. Since July 1, 2003, equipment manufactured for operation in potentially explosive environments has been required to comply with the European Directive 94/9/EC. This directive, commonly referred to as the ATEX Directive, applies to all countries in the European Union (EU) and the European Economic Area (EEA). The ATEX Directive is a collection of EU directives outlining equipment installed and operated in potentially explosive atmospheres. The ATEX directive coordinates various technical and legal conditions throughout Europe to ensure a high level of safety for the end-user by reducing the explosion risk through established design methods. The European Committee for Standardization (CEN) published EN 14986 as a standard specifically for the manufacture of fans for use in hazardous areas. This standard is a guide specifically for fan manufacturers to comply with the ATEX Directive.
The reversible propeller incorporates specifically engineered airfoil sections and hub size for optimal efficiency and physical strength. Alternate adjustable pitch propeller blades are turned 180 degrees to one another and a double orifice is attached to the fan panel.
