FRP Damper Valve
SILL damper utilizes only high corrosion-resistant parts for air movement and controls. SILL dampers are fire retardant, corrosion resistant, and UV resistant.
The SILL damper blade is operated using a hand-wheel driven worm gear operator. Pneumatic, electric, or chain-wheel type operators are optional. Long life is often being accessible from the exterior of the damper pipe section, unlike most available dampers that require full unit replacement.
SILL dampers enhance safety by providing greater isolation of process air during shutdown of low-pressure exhaust systems that are lines conveying hazardous air streams. When dealing with confined space entry conditions, use of SILL dampers may reduce serious risks caused by contaminant air leaks.
SILL dampers require far less maintenance, are more durable, and outperform conventional butterfly dampers.
SILL dampers range in sizes from 4-inch diameter to 120-inch diameter.
