VCD | Rectangular - Single Skin Blade Construction


Volume Control Damper:

Aerovac rectangular Volume Control Dampers (VCD) with single skin & double skin aerofoil blades are widely used in heating, ventilation, air conditioning (HVAC) systems. Unique construction and manufacturing technique coupled with superior design make the series AV 11 & series AV 22 damper quiet & reliable giving conditioned controlled air volume to various zones.

  • The frame is constructed from galvanized steel sheet.(Also available in aluminium& stainless steel construction)

  • Blades are coupled by external concealed linkage / Gear Drive, which can be provided in either opposed or parallel blade operation, Blades can be provided with either single skin or double skin based on the requirement.

  • Linkage rods are coupled with hand locking quadrant frame in a "open & closed" marking. Hand locking quadrant frame is marked to show exact position of damper

  • Structure is available with flange edge and supplied undrilled as standard.

  • Designed for HVAC systems.

    Rectangular - Single Skin Blade Construction:

    AEROVAC low leakage Volume control dampers are most popular choice for use in low to medium velocity and pressure commercial HVAC systems. They are low cost, high quality dampers that meet the frequently specified leakage criteria of less than 8cfm per sq. ft. at 4" w.g. (148 M3/hr/M2).

    Design features include durable steel construction, a sturdy 20-16 ga. galvanized steel hat channel frame with die-formed corner gussets providing superior structural strength equivalent to 13 ga. (2.4 mm) channel type frames, an interlocking vee groove blade design that maximizes strength and optimizes airflow, double bolted / riveted no slip blade axle connections with Brass /Nylon bearings, Silicon extruded blade seals and a no-maintenance concealed linkage located within the side frame out of the air stream for reduced pressure drop, air turbulence and noise. A variety of electric or pneumatic actuators are available for factory or field mounting along with a comprehensive selection of options to meet specific installation requirements and applications.
