Motordamper GFD - ø80 mm to ø500 mm GEOVENT fast turning on / off damper GFD is specially designed for use in point extraction systems that require rapid opening and closing of the dampers at suction points. GFD is a close damper that can open 90° down to 1 second. Rotating speed can be set between 1 to 5 seconds (use ø315, ø400 or ø500 mm). This damper is also available with modulating motor for fume hoods and fume for accurate control of the air. The damper is available from ø80 mm to ø500 mm Actuators >> Technical data sheet Power supply: Power consumption: level Sound power Technical data Functional data Shaft coupling Wire dimenstions: Safety 1 m Cabel, >1 500 000 partial cycles (max. ±5°) Position indication Service life mechanical with pointer > 100 000 cycles (0°...95°...0°) 2 Nm III (safety extra-low voltage) IP 54 (cable downwards) Protection class Degree of protection EMC LVD RoHS Mode of operation Rated impulse voltage Control pollution degree Ambient temperature normal operation Storage temperature Ambient humidity CE (2014/30/EU) CE (2014/35/EU) CE (2011/65/EU) Typ 1 (EN 60730-1) 0,8 kV (EN 60730-1) 3 (EN 60730-1) -30°C...+50°C -30°C...+80°C 5...95% r.H., non condensing (EN 60730-1) maintenance free Ambient temperature: Maintenance Dimensions / Weight Ordering table Dimensions Protection class: Weight Sound level: Operating mode / Properties Mode switch with five positions at the housing: Mode switch 1: Rotary direction switch with five positionsVDC right 2-10 at the Through connecting the power supply to Mode BU+BN (1+2) and a reference signal Y to housing: 2: Rotary direction right 0-10 VDC BK (3) of (0)2...10 VDC, moves the actuator to its specified position.
