F2A AS Back Draft Damper

F2A AS back draft damper is designed for a one-way air flow direction. The blades prevent reverse flow in the ductworks. It is suitable for commercial and industrial HVAC applications. Dimensions: - Minimum: 200 x 180 mm - Maximum: 2000 x 1995 mm - L with a pitch of: 100 mm - H with a pitch of: 165 mm - Blades height: 82.5 mm - Frame width: 125 mm Material Options: - Frame: Galvanised steel, aluminium, stainless steel 304 or 316L - Blades: Aluminium, stainless steel 304L or 316L Performance Characteristics: - Acceptable pressure: 150 Pa for a length of L = 1m - Operating temperature: -20 to +80°C - Air velocity: between 2 and 5 m/s - Adapted to high overpressure - Painting (optional) Function: AS back draft damper ensures air flow in only one direction. The blades automatically close when air flow reverses, preventing reverse flow. This feature improves system efficiency and prevents unwanted air flow. Advantages: - Reliable one-way air flow - Wide size range - Multiple material options - High pressure resistance - Wide temperature range - Suitable for industrial applications
