EN 664.1 Elesa® original design filler strainer units.
EN 664.1 filler strainers are available with mounting flange for threaded or bayonet (BA) connection. Filler strainers prevent the entrance of coarse impurities during the refilling process.
The side flange is fitted with 7 M6 screws on the wall of the tank. When installing the flange it is important that these are not overtightened (max. torque 8 Nm) to prevent deformation of the flange and possible weakening of the seal.
