The canopy is fabricated entirely in type 304 stainless steel (1.0 – 1.2mm) thick. All visible surfaces are ultra fine grain polished (320 grit) and polythene protected. The canopy is cut, punched and folded into seamless sections up to 6m in length and factory assembled by means of computer controlled seam welds and non visible mechanical fixings. Joints are provided with internal cover-plates so that no joints or mechanical fixings are visible. All metal edges are rolled smooth and are free from sharp edges and projections. The canopy lower edge is formed into a condensation channel with inclined internal elevation to simplify cleaning and the inner edges are crush folded for safety purposes. The canopy is equipped with Vianen Fecon grease extraction baffle filters. The filters are designed to allow the grease to run off the filters into an integral grease collecting channel and then into easily removable grease trays. The canopy has a constant exhaust pressure drop of 100 Pa, an Jet Stream supply air pressure drop of 90 Pa and a front face supply pressure drop of 40 Pa.
