Opposed blade dampers suitable for systems requiring air control (Aerofoil) and low closed blade leakage (Aeroseal).

Description

The AirShield range of quality engineered dampers are suitable for air conditioning and ventilation systems requiring air control and low closed blade leakage characteristics. For standard low/medium pressure and velocity systems.

These aerodynamic precise movement opposed blade dampers can be either factory fitted with manual, electric or pneumatic controls and can be supplied in a flanged or spigotted casing.

Actionair AirShield Dampers are designed for applications in normal dry filtered air systems. When required for modulating function, or if exposed to fresh air intakes and/or inclement conditions, the dampers should be subject to a planned inspection programme.

Construction

Series Aerofoil

Series Aerofoil for system air balancing having aerodynamic ribbed double skin type 1.4016 (430) Ferritic Stainless Steel 50mm wide x 0.4mm thick blades. Housed within a galvanised mild steel flanged or galvanised spigotted casing being suitable for systems with a temperature range of ?20 ?C through to +70 ?C.

Series Aeroseal

Series Aeroseal for system air balancing and shut-off having aerodynamic double skin type 1.4016 (430) Ferritic Stainless Steel 50mm wide x 0.4mm thick blades with synthetic trailing edge blade seals and Stainless Steel side seals. Housed within a galvanised mild steel flanged or galvanised spigotted casing being suitable for systems with a temperature range of 0 ?C through to +70 ?C.

Optional Blade construction type 1.4401 (316) Austenitic Stainless Steel.

Specification

AirShield Aerofoil

Air control and system balancing dampers comprising of 50mm ribbed stainless steel aerodynamic blades with synthetic blade end bearings. Housed in either a galvanised mild steel frame having integral peripheral flanges, with prepunched corner holes to suit proprietary duct flanges (Type FLA) or with spigot plates on both sides, for square, rectangular, circular or flat oval connections (Type SPG). The totally enclosed precise movement opposed blade mechanism positioned out of the airstream for protection against damage is hard wearing and free running. AirShield Aerofoil as supplied by Actionair.

AirShield Aeroseal

Air control and system balancing shut-off dampers comprising of 50mm stainless steel aerodynamic blades with synthetic trailing edge blade seals, synthetic blade end bearings and stainless steel top and side spring tempered flexible gasketing. Dampers to have a maximum closed blade leakage of 27 l/s at 1000 Pa when measured on a 1000mm wide x 1000mm high damper. Housed in either a galvanised mild steel frame having integral peripheral flanges, with prepunched corner holes to suit proprietary duct flanges (Type FLA) or with spigot plates on both sides, for square, rectangular, circular or flat oval connections (Type SPG). The totally enclosed precise movement opposed blade drive mechanism positioned out of the airstream for protection against damage is hard wearing and free running. AirShield Aeroseal as supplied by Actionair.

AirShield

Aerofoil dampers are supplied fitted as standard with type Manual Control (Option M). Aeroseal dampers are supplied fitted as standard with type Manual Quadrant Control (Option Q). Aeroseal Stainless Steel dampers are supplied with type Manual Quadrant Control (Option Q) fitted as standard. Aeroseal dampers can be factory fitted with one of the alternative control options as detailed on page 5 (Aeroseal and Stainless Steel dampers not suitable for Option M).
