ETD Series, Spigotfit, 430 Grade Stainless Steel Blades. Hand Operated

The ETD Series Damper is designed for the control of air through the connecting ductwork and is suitable for continuous elevated temperatures up to 300°C.

It can also be used in conventional ducted systems where manual or motorised control dampers are called for, ensuring high performance in demanding environments.

The ETD Series damper is designed for the control of air through the connecting ductwork and is suitable for continuous elevated temperatures up to 300°C.  Exposure to temperatures greater than this will compromise the case leakage.

Its design, construction, and material selection ensure a high quality, low-maintenance product that is manufactured, supplied, and installed.

The ETD Series control damper is not intended to comply with EN12101-8 Smoke and Heat Control Systems – Smoke Control Dampers.
