Commercial building codes are mandating higher volumes of fresh-air intake than ever before. To help meet these ventilation requirements, more and more HVAC contractors and building owners are turning to dedicated outdoor air systems (DOAS). 

CertainTeed has introduced its newly enhanced Sustainable Insulation™ SoftTouch™ Duct Wrap, which the company said offers HVAC contractors improved cutting and handling to ease installation, while maintaining fiberglass product performance.

This AKSD axial fan delivers up to 5,585 cfm with an improved mix of airflow and static pressure.

MBI Centrifugal In-Line Fans are designed for residential and light commercial ventilation applications. 

The Dr. PTAC option is available in Islandaire’s EZ Series DR product line and in the EZ Series VR (vertical unit).

Not all ventilation installations are designed and executed properly, and it is not uncommon to find improperly performing ventilation systems. 

Fan products are not only more efficient and quieter — they’re also smarter, more intuitive, and more connected than ever before.
