Elta Matching Flanges 400mm

The Elta 061B-0400 is a 400mm matching flange that bolts directly to the case flange of an Elta fan, giving an easy, square connection to ductwork, a flexible connector or a silencer.It is made from 1.5mm hot dip galvanised steel with an outside diameter of 475mm and 8 fixing holes of 12mm diameter on a 450mm PCD, and weighs 1.2 kg. One flange fits one end of the fan. 400mm matching flange Fits directly to fan case flange Hot dip galvanised steel What it is best used forConnecting a 400mm Elta long cased or inline fan to 400mm ductwork, a flexible connector or a silencer, in kitchen extract, car park, plant room, warehouse and general supply or extract systems. Elta list the 061B matching flanges on the accessory tables for their Revolution SLC and SLCX ATEX long cased fans.One flange connects one side of the fan, so order two for a ducted inlet and outlet. Elta's SCD and SDA cased fans take their own 061A flanges, not this 061B part. Check the fan size and drilling before ordering.Why choose this over alternativesCompatible 400mm fans on eFans that list 061B matching flanges: SLC400 three phase AC, SLC400 EC and SLCX400 ATEX. Using Elta's own flange means the hole pattern suits the fan case without drilling, and the hot dip galvanised finish resists corrosion in plant rooms and ducts.Neighbouring sizes: 350mm and 450mm. For a vibration break between fan and duct, Elta pair the flange with a flexible connector; ask us for the matching 063 flexible connection or the APK ancillary pack, which bundles flanges, flexible connections, anti-vibration mounts and feet.Installation notes Bolt the flange to the fan's case flange, lining up the equally spaced fixing holes; use one flange per ducted side. Seal the joint between flange and fan case with a suitable gasket or sealant so the connection is airtight. Fit a flexible connector between the flange and the ductwork to stop fan vibration travelling into the duct. Support the ductwork independently so its weight does not han
