Belimo AV8-25 3/4" Shaft Extension Fit 5/16"-1" DIA

The Belimo AV8-25 Shaft Extension Fit is an additional part that is used in the extension of the length of the damper shafts in HVAC systems with shaft diameters of between 5/16 and 1 inch. This extension is constructed from galvanized steel and is designed to accommodate damper shafts to be compatible with the Belimo actuator models LF, LMQ, and NF series. Its main purpose is to add more distance to the actuator arm to achieve better control of air dampers in applications such as fan coils and air handling units.
