Guillotine / Slide Gate Dampers

Guillotine / Slide Gate Dampers

Slide Gate or “Guillotine” Damper are most commonly specified when positive isolation for maintenance is the primary function of the damper and also for severe service conditions. Guillotines are classified in two styles: Low Leak and Zero Leak. Both styles are ideal for a high degree of isolation while providing low pressure drop when the dampers are in the open position. Guillotine dampers are commonly used in systems that require routine access to a duct, i.e.; maintenance, inspection, or repair. Typical heavy duty applications include: Steel mills, Power plants, cement plants, reformers, petrochemical, and heavy duty exhaust systems.


Low Leak Slide Gates

Low leak slide gates are primarily used for isolation purposes where low levels of leakage and pressure drop are required. Low Leak applications include isolation for systems that function under negative pressure or require a tight shut-off to aid in the systems process. (i.e.shaking the bags in a large bag house)


Zero Leak Slide Gates

Zero leak slide gates are used when zero-leakage isolation is required. Zero leakage isolation is accomplished by pressurizing the seal air chamber that surrounds the blade edges. When compared to a double louver, the zero leak slide gate requires less seal air and flange to flange space; therefore, it can be used in tight runs of ductwork.
