Greenheck adds two new products to automatic balancing damper line
Greenheck recently announced two new additions to its automatic balancing damper (ABD) line.
First, the Model ABD-FD, which incorporates a UL 555 rated 1-1/2 or 3 hour static fire damper, flanged sleeve, an ABD and an optional factory-supplied grille.
The entire ABD-FD assembly is UL rated and approved and can be used in both supply and exhaust applications.
Also, the ceiling radiation damper CRD-1WT, UL classified for wood truss floor/ceiling assemblies, now has the option to add an ABD mounted in the plenum box.
Pressure independent automatic balancing dampers are designed to maintain constant airflow volume in HVAC applications. The damper blade is calibrated to automatically adjust to changing pressures.
