Mounting Orientation: Why a Damper That Works Sideways Fails Upright
Shaft horizontal or vertical, actuator above or below, housing on the pressure side or the suction side. Three choices that decide how long the gate…
Technical articles
Sealing systems, material selection, maintenance practice and selection guidance — written by the people who build the gates.
How Much Sealing Air Does a Damper Gate Actually Need?
The 0.5 % rule of thumb, when it is wrong, and the measurement that proves the seal on the day the permit is signed.
Noise From Dampers in Flue and Air Ducts
Where damper noise comes from, why partly open is the worst position, and the three fixes that actually work.
Process Requirements for Flue Gas Damper Gates
A flue gas damper gate is made up of a frame, blades, sealing strips, main shaft, bearings, shaft seals, crank linkage, actuator and the gate body…
Features of Flue Gas Damper Gates
Double gate construction, sealing air in the cavity, 60-second travel, external linkage and a choice of electric or pneumatic drive — the anatomy of…
Why Airtightness Decides the Value of a Flue Duct Slide Gate
A slide gate is what stands between a maintenance crew and a live flue. Its airtightness is not a performance figure, it is a safety requirement.
Why the Sealing System of a Flue Damper Gate Matters Most
Mechanical seal, sealing air cavity, sealing air fan set. Three layers that together decide whether the gate is actually tight under a large pressure…
