Greenheck Expands Automatic Balancing Damper Line
Greenheck has added two new products to its automatic balancing damper line. Model ABD-FD 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. 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.
