Air/Shield (Incorporating Energy/Shield ES35 & ES36)IntroductionProduct SizingActionair has announced a majorenhancement to the company’s wellprovenAir/Shield range of opposedblade dampers.To maximise the potential number ofsingle-module / single-driveconfigurations, the range has beencomplemented by the addition ofEnergy/Shield Dampers for ductworkapplications above 1000mm in width.Thus, Energy/Shield ES35 units cannow be selected for air balancingrequirements for flanged ductworkabove 1000mm X 1000mm. Shut offdamper requirements for ductwork inthese sizes can be met byEnergy/Shield ES36 models, where asingle drive is required. Smaller sizesare also available in a flanged stylecasing.For ductwork in sizes below thesedimensions the range of Air/ShieldAerofoil (air balancing) and Aeroseal(shut off) Dampers will continue toprovide a quality engineeredsolution.Aerofoil Air Control DamperAeroseal Air Control and Shut-OffDamperMaximum versatilityTo ensure maximum versatility ofapplication flanged Energy/ShieldES35 and ES 36 units will beavailable in 1mm height increments,while specifiers may opt for eitheropposed blade or parallel bladeaction according to requirement.For ducts up to 2080mm in width x1000mm in height these new flangedmodels can be powered by a singledrive to minimise unit cost andmaintenance requirements. Bladedrive mechanisms are mounted outof the air stream to minimisepressure drop and noise generation.The entire combined range ofAir/Shield Aerofoil, Aeroseal andEnergy/Shield ES35 and ES36models is suitable for use with totalsystem operating pressures up to1000 Pa and velocities up to 12m/s.Casing leakage conforms to DW144Class C up to 1000 Pa.ES35 Air Control DamperAir/Shield Aerofoil and AerosealFLA (single drive arrangement)Widths from 100mm minimum –1000mm maximum, (in 1mmincrements).Heights from 100mm minimum –1000mm maximum, (in 50mmincrements).Air/Shield Aerofoil and AerosealSPG (single drive arrangement )Widths from 100mm minimum -1000mm maximum, (in 1mmincrements).Heights from 100mm minimum –1000mm maximum, (in 1mmincrements).Air/Shield Aerofoil and AerosealCircular (single drive arrangement)Diameters from 100mm minimum –1000mm maximum (in 1mmincrements).ES36 Air Control and Shut-OffDamperAir/Shield Aerofoil and AerosealFlat Oval (single drive arrangement)Widths from 300mm minimum –1000mm maximum, (in 1mmincrements).Heights from 100mm minimum –500mm maximum, (in 1mmincrements).Energy/Shield ES35 and ES36 FLA(single drive arrangement)Widths from 200mm minimum –2080mm maximum, (in 1mmincrements).Heights from 200mm minimum –1000mm maximum, (in 1mmincrements).Dampers from 1201mm minimum -2080mm maximum in width will besupplied with a mullion (80mm wide),factory fitted joining strip and hexagonalcouplings. This single drive arrangementis supplied as a complete unit.2

Air/ShieldAir/ShieldThe RangeThe Air/Shield range of qualityengineered dampers are suitable forair conditioning and ventilationsystems requiring air control and lowclosed blade leakage characteristics,for standard low/medium pressureand velocity systems.These aerodynamic precisemovement opposed blade damperscan be either factory fitted withmanual, electric or pneumaticcontrols and can be supplied in aflanged or spigotted casing.Application ParametersAir/Shield Dampers to maximumwidth and height dimensions (seepage 5) can be used where theoperating total system pressure is upto 1000 Pascals and duct velocitiesto 12m/second.Actionair Air/Shield Dampers aredesigned for applications in normaldry filtered air systems. Whenrequired for modulating function, or ifexposed to fresh air intakes and/orinclement conditions, the dampersshould be subject to a plannedinspection programme.Any application involving corrosiveand/or aggressive hostileenvironmental conditions (e.g.swimming pools) may invalidate ourwarranty and should be referred toActionair Sales Office.Blade FeaturesSeries AerofoilSeries Aerofoil for system airbalancing having aerodynamicribbed double skin type 1.4016 (430)Ferritic Stainless Steel 50mm wide x0.4mm thick blades.
