Being accountable for proper airflow delivery causes a tech to examine every portion of an installation differently. Airflow is no longer assumed since test instruments now measure it. Let’s look at some of the most common obstacles to achieving a successful air balance on a residential HVAC system.

Greenheck’s Vektor line of laboratory exhaust systems now offers a direct-drive arrangement with four-options available on Vektor-MH (High Plume), Vektor-MD (High Plume with Dilution), and Vektor-MS (Variable Geometry Nozzle) models.

The Backward Curved Centrifugal Fan, equipped with a plastic impeller, is high-voltage powered by a built-in electronically commutated motor (ECM), which enables the fan to run efficiently with low-energy transmission loss.

These two types of commercial modulating Duct Boosters are for multi-dryer venting through a single duct.

The Model ABD-SEA-E provides precise and automatic airflow regulation for supply or exhaust ventilation systems in any residential or commercial building. It is designed for use in any HVAC application with a static pressure between 0.2 and 2.0 inches water column.

The ventilation market, much like the rest of the HVACR industry, is being driven by the need for more energy-efficient products.

These flexible fan packs are engineered to meet stringent low-noise and efficiency requirements in industrial and commercial ventilation, refrigeration, and heat exchange applications.

The Smart Building Gateway (SBG) provides continuous ventilation management system monitoring from any internet connection. Via the SBG, facility managers and contractors can gain instant, live access to all air-quality parameters and immediately determine whether the ventilation management system is operating at optimal efficiency and maintaining healthy IAQ.

The OPTIMISER 10 is an easy-to-use resource for original equipment engineers to specify the most efficient, tailor-made Multi-Wing fan for their applications.

Equipped with a plastic impeller, this high-voltage fan is powered by a built-in electronically commutated motor (ECM), which enables the fan to run efficiently. Designed for residential uses, the centrifugal fan is widely applied in HVAC, air movements, or home appliances.
