Swingout construction on the 69S power roof ventilator provides easy, safe access to internal fan components for inspection, cleaning, maintenance, or repair without removing the entire fan assembly or having personnel working directly over the roof opening.

Energy Star-rated, the WhisperRecessed™ ventilation fan is a combination of an 80-cfm fan and light that is recessed into the ceiling, offering quiet, energy efficient, and powerful ventilation. The compact fluorescent lamp provides diffused, uniform illumination. The specification-grade, fan-light includes the Dual Duct Adapter.

Increasing the coverage area and warranty of the company’s Power-foil® X is the Powerfoil X2.0 industrial fan. The fan introduces an airfoil system that combines patented airfoils and winglets with patent-pending AirFence™ technology to increase overall coverage by 28 percent, said the company.

An ac three-position short fan tray is now available with an energy-efficient smart thermal control. Designated the OA300ST Series, the smart thermal controller independently increases or decreases the speed of the three fans in response to the ambient air temperature, reducing power consumption by up to 30 percent.

Designed for use in residential applications where homeowners’ rooms are uncomfortably hot or cold because their forced-air furnace/air conditioner blower cannot provide adequate velocity, the Duct Booster® register booster fans can now increase comfort.

When space restrictions prevent the use of in-line duct fans, EXT External Mount Duct Fans can be used, said the company. EXT fans provide a simple through-the-wall solution, and can be sidewall mounted on the exterior of a building to allow for easy access to the fan. Installation space can be as little as 4 inches.
