Air/ShieldControl OptionsTechnical DataManual Control (Option M)Always fitted as standard on Series Aerofoil units. Not suitable for Series Aeroseal or anyStainless Steel options.Consists of a redknob and slimlinecontrol box withblade positionlocking facility(a no. 6 pk screwsupplied and fittedby others piercesthrough membranein the control box)and visual bladeposition indication.TypeFLA/SPG534 65Manual Quadrant Control (Option Q)Always fitted as standard on Series Aeroseal and also on all Stainless Steel options.Consists of a darkbrown steelhandle, bladeposition lockingfacility andquadrant bracketwith visual positionindication.TypeFLA/SPG61009814018316Type SPGStainless SteelDamper TorqueThe rotation of damper blades fromthe fully closed to the fully openposition produces the greatesttorque. The largest torque is alsodependent on the fan and systemcharacteristics.Series Aerofoil dampers to themaximum size of 1000mm wide x1000mm high or 1000mm diametergenerally require no more than 10Nmtorque.Series Aeroseal dampers to themaximum size of 1000mm wide x1000mm high or 1000mm diameterrequire no more than18Nm torque.The above torques are to rotate thedamper from the fully closed to thefully open position against therecommended maximum total systempressure of 1000 pascals and themaximum duct velocity of 12m/s.31256247Extended Shaft Control (Option X)A solid 12.7mmdiameter stainlesssteel shaft marked toprovide visual bladeindication completewith support bracketfor attachment ofcouplings and/orlinkages formotorisation byothers.(Shaft rotatesclockwise to closedamper).12.7 DIA1272758CLOSED60OPEN164312.7 DIA143Electrical Controls (Option E)Factory fitted Belimo Actuators for24V or 230V open/closed or springreturn operation and 24V modulatingare available.
