Air Control and Shut­off Dampers

Description

The EnergyShield range of dampers are suitable for air conditioning and ventilation systems requiring air control and low closed blade leakage performance. Blade construction for system pressures up to 1000Pa and duct velocities of up to 10m/s on the EnergyShield ES35 and EnergyShield ES36 range and 1500Pa, and 20m/s on the EnergyShield ES50 range. Suitable for applications in normal dry filtered air systems, including modulation function. If exposed to fresh air intakes, and/or inclement conditions, the 316 stainless steel option should be considered by the client (EnergyShield ES35+36). All installations should be subject to a planned inspection programme, frequency of which is dependant upon application and environmental conditions. For specialist applications and products outside specified parameters, please consult with our Technical Sales Office.
