Continental Fan's TEK Plenum Fans feature TEK backward curved airfoil wheels. The impellers combine precision injection molding techniques with modern high-strength plastics to produce a wheel that is stronger than steel, yet half its weight, according to the company.
Greenheck’s new Utility Set Fan (USF) Series offers multiple levels of construction to meet a wide range of commercial and industrial applications. Constructed from galvanized steel with a bolted frame, USF-200 utilizes a backward inclined centrifugal wheel and is ideal for Class I airflow and pressure applications where clean air is being exhausted. USF-200 capacities range from 50 to 13,700 cfm and up to 5.0 in. wg.
ClimateCraft has supplemented its FanMatrix™ fan array system with the new BalanceStream™ technology. Featuring a spring-actuated inlet cone and designed with only one moving part, the company says its BalanceStream improves system efficiency, flexibility, and simplicity while reducing maintenance and energy costs. ClimateCraft has engineered the technology to incorporate no supplemental electro-mechanical devices, nor require a complex control strategy. Additionally, BalanceStream eliminates the need for backdraft dampers, and features automatic shut-off in the case of fan failure. FanMatrix with BalanceStream technology is available for replacement fan installations, or easily retrofitted into existing FanMatrix systems.

The UV-Com™ Control Panel from UV Resources provides a convenient means of monitoring multiple Ultraviolet “C” (UV-C) fixtures installed in individual AHUs. The UV-Com automates the conventional means of “manually checking” that lamps and ballasts are operational and communicates this lamp status to most BAS/BMS. A single UV-Com control panel can simultaneously monitor up to eight separate UV-C fixtures. Multiple UV-Com panels can be linked together in a daisy-chain sequence in order to monitor as many individual UV-C fixtures as necessary.
