GREENHECK, a global leader in manufacturing and distributing air movement and control equipment, has introduced Model SWD, which is claimed to be the industry’s first direct drive, backward-inclined utility fan to utilise an electronically commutated (EC) motor.

The fan is powered by Greenheck’s energy-efficient Vari-Green motor, says a spokesman for the US-based manufacturer.

“Model SWD achieves the performance of Greenheck’s Model SWB belt-drive centrifugal utility fan, including higher operating efficiencies and higher pressure capabilities, available for variable volume airflow applications without the need to change belts,” he adds.

Model SWD is available in seven sizes (7 through 18) with capacities from 100 to 5,860 cfm and up to 2.5 in wg (inch water gauge), and is suitable for ducted exhaust, supply and return-air applications typically found in commercial kitchens and fume hoods.

Meanwhile, Greenheck has produced a new 16-page energy guide on fan efficiency grades to provide customers with an insight on fan efficiency grade (FEG) ratings and additional recommendations for reducing fan energy usage.

The guide also details Greenheck fans that are licensed to carry the FEG-certified AMCA seal. Nineteen Greenheck fan models bear the FEG AMCA seal including Model QEI/QEID mixed flow fans, Model HPA housed plenum fans, and Model QEM/QEP plenum fans.

In addition, Greenheck has also highlighted components found in integrated ventilation systems in a variety of commercial buildings including schools, offices, hospitals, warehouses and restaurants in a new 14-page brochure.

“Buildings benefit from utilising integrated ventilation equipment from a single-source. The brochure explains how Greenheck designs whole-building ventilation system solutions for specialised needs,” says the spokesman.

Information is also included on Greenheck’s computer-aided product selection (CAPS) programme and Quick Build shipping programme.

Greenheck offers a wide range of air movement and control equipment including fans, dampers, louvres, kitchen ventilation hoods, and energy recovery and make-up air units which are used in all types of commercial, institutional, and industrial buildings in applications.
