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.

A brochure details Model RV/RVE, pre-engineered rooftop ventilation units designed to condition and deliver mixtures of outdoor and return air to a building. The rooftop ventilation units feature 2-inch double-wall construction, coupled with direct-drive plenum fans, heating options, cooling options, and optional energy wheel.

Compact yet powerful, the AFK direct drive flange fan is available in diameters from 12 to 42 inches, with capacities ranging to 34,000 cfm. The unit, which has heavy-gauge steel with baked polyester coating, can be built for supply or exhaust configurations.

The WhisperRecessed™ ventilation fan is an 80-cfm fan-light combination that is recessed into the ceiling offering quiet, energy-efficient, and powerful ventilation. The Energy Star®-rated compact fluorescent lamp provides diffused, uniform illumination with the 18-W CFL bulb.

With the ability to operate as a standalone system or be integrated with a building automation system, the MatrixMonitor™ is a digital instrument that gauges airflow in fan arrays containing three to 98 fans, with maximum airflow of 300,000 cfm per array.

Although the project had to be redesigned more than once, the Almost Home Animal Shelter in Fort Dodge, Iowa, has now been efficiently operating for more than a year with a dedicated outdoor air system (DOAS) and an integral energy recovery wheel.
