Application area
VCR1 and VCC1 are manually operated control dampers designed to regulate air flow in ventilation systems. VCR1 is a rectangular type and VCC1 is a circular type damper.
The solid construction withstands high air flows and pressure variations. Air leakage through the blades in the closed position is kept to a minimum on the control damper and leakage through the unit is negligible.
The control damper has opposed blade types, manually operated via link arms with a handle, and positioned with a solid locking device. A degree scale indicates blade positions for volume control dampers and an open/closed indication on control dampers. Limit switches for remote open/closed damper indications are a possible alternative.
Materials and dimensions
The balancing damper casing is manufactured in stainless steel AISI 316L. The plate thickness is 3 mm. The blades have a plate thickness of 1.5 mm with cell rubber sealant. Both axles and bearings are made of stainless steel.
Test data
Test data is based on the NS-EN 1751 standard for both air leakage through closed leaves and leakage through the enclosure.
