120 Vac Dampers

Motorized dampers for sites where only line voltage is available at the damper, with no 24 Vac control circuit to run. The HAC-12 series has a transformer built into the damper, and the Belimo models accept 100 to 240 Vac (or 100 to 230 Vac) directly. Where 24 Vac is practical, use it: every product here has a 24 Vac equivalent.

Choosing a 120 Vac damper

• Round duct, 4 to 9 in.: the HAC-12 on the stall-protected Hoyme spring return drive, with a built-in transformer. CSA certified.
• Damper in cold or unconditioned space: the HAC-12L, the same damper with a factory-insulated body. CSA certified.
• Zoning on a single-speed furnace: the HAC-12H with the 10% heat bypass blade. CSA certified.
• Round duct, 6 to 20 in., on/off: the HAC-44 with a Belimo TFB120 spring return actuator, 100 to 240 Vac.
• Round duct, 6 to 20 in., floating point: the HAC-35 (Belimo CMB120-3) or the higher-torque, power open only HAC-70 (Belimo LMX120-3). Both hold their last position on power loss.
• Fire and smoke actuator: the HAC-80 with a Belimo FSLF120 US. The damper assembly is not UL listed and is not a listed fire or smoke damper.
• Rectangular duct: custom HCR/HSI dampers with a Belimo TFB120, built to your dimensions.

The HAC-12 series is CSA certified. The Belimo 120 Vac models in this collection are not.
