LSS / SOD – circular single blade shut off damper SSVent – rectangular multiblade shut off damper S.Ventil R1OVL – circular single blade weather tight damper/valve RD – circular regulating damper BFD – back flow (non return) damper BSS – combined fire damper A0, A30 with silencer

NYBORG CIRCULAR SHUT OFF DAMPER APPLICATION Used as shut off damper (for non weather tight applications) often mounted directly to fans or hoods. Single blade damper gives low pressure drop, and is suitable for applications with high air speed. Can also be used as regulating damper. Typically used for small to medium fan sizes. SPECIAL DESIGN  Short casing (damper popping out of one or two side of damper)  Combined damper with circular silencer.  With thick walled casing for high vertical loads /open deck mounting. EXECUTION Casing/housing made of mild steel, hot dip galvanized. Damper blade...

NYBORG CIRCULAR SHUT OFF DAMPER APPLICATION The SSVent is a rectangular multiblade shut off damper with circular adapter for mounting directly to axial fan or circular duct. It can also be mounted directly on bulkhead or in rectangular duct. Additional to shut off damper it can also be used as a regulating damper. Suitable for medium to bigger fans ACTUATOR: Electric 24-230V (non EX and EX for zone 1 or 2), pneumatic (non EX and EX for zone 1 or 2) or manual actuator. All electric or pneumatic actuators fail safe and with limit switches as standard. Pneumatic actuators also with solenoid valve...

NYBORG RECTANGULAR SHUT-OFF DAMPER NYBORG RECTANGULAR SHUT-OFF DAMPER, DESIGNED FOR CIRCULAR APPLICATION, SSVent BxH, made of hot dipped galv. Steel. Damper blades and shafts in AISI 316L. Adapterplate is made of hot dipped galv. steel. Equipped with electrical or pneumatical actuators.

BACK FLOW DAMPER APPLICATION The back flow (or non return) damper is used in ventilation system where back flow or return air is to be prevented. Typically used for two fans in parallel (one running, one standby) to prevent backflow over idle fan. The damper is fully mechanically, opening on air flow, closing on gravity. SPECIAL DESIGN Can be made with smaller depth (200 and 250 mm) if space is limited. INSTALLATIONS  Vertical (for horizontal air flow)  Horizontal, air up  Horizontal, air down (should be used with caution) EXECUTION Designed for marine application. Standard execution in aisi316L,...
