CMR is the manufacturer and designer of the popular FGG Flowgrid. All FGG Flowgrids are made to measure. They are made of anodized Aluminium with a galvanised steel duct frame. They are made height increments of 100mm and width increments of 50mm. The dimensions are made for ducts from 100mm x 100m up to 1200mm. The length of the Flowgrid is always 300mm with a Standard Flange Size of 30mm allround. The FFG Flowgrid is complete with averaging pressure tanks. The Flowgrids should be installed preferably in a horizontal position which means if a duct is 300mm x 500mm, the height is 300mm and the wdth is 500mm with the nipple connection on the horizontal side.
The FGG Flowgrids can be fitted in any position except after a controlling damper or close to a duct T- Piece. As an optional extra, the FGG Flowgrids can also be epoxy coated.
