Description

	The TD TRIF circular diagonal duct fans are designed for installation in circular ducts. The fan housing is made of galvanized steel sheet with epoxy coating. The fans are equipped with fiberglass sound insulation. The terminal block is located on the fan housing. The easy-to-remove TD TRIF fan motor unit is housed in an integrated mounting bracket that allows an easy wall or ceiling mounting. Speed control is done by changing the voltage or by frequency converter. The TD TRIF diagonal fans can be installed in a horizontal or vertical position. The unique design of the support bracket allows mounting or dismantling of the motor and impeller assembly without dismantling the ducting.
