Low Leakage Control Damper, HD-LL Series, Non
Insulated Aluminium Blades, Circular, 140mm Case
Depth, Electric Motor, NFA-S2 (SC)
100mm DIA

The HD-LL series damper has been designed for air conditioning and ventilation systems requiring air control and low closed blade leakage performance. The aerodynamic aluminium reinforced blade design requires only a single blade edge seal to the trailing edge. The blade seal profile has an engineered shoulder design to ensure a positive sealed connection between the blade and fitted seal. The blade seal acquiescent profile design accepts the blade leading edge of the interconnecting adjacent blade ensuring a good compressible seal with minimum torque, returning to its original form when the blades re-open. Control can be effected by a manual quadrant, fitted actuator of choice or extended spindle for actuation by others. The BSB HD-LL Series Low Leakage Heavy Duty dampers are available in a variety of vertical or horizontal mounting configurations from 100mm square/dia. to 1000mm square/dia. Casing 1.2mm (18swg) galvanised mild steel to BS EN 10346 specification DX 51D Z275. Coating Class Fe P02b Z275 Na. When circular or flat oval spigots are supplied, the material will be 0.7mm zintec for the spigots only. Blades Extruded airfoil aluminium to BS EN 755 Part 9 specification 6063 T6, wall thickness 1.25mm (18swg) minimum.
