UFK sills fixed aluminium blades which are streamlined to give a stable flow pattern. The grille is mechanically very strong and can consequently handle large external loads. The universal grille can be put together on site to unlimited lengths.

Design

The grille consists of strong aluminium profiles held together by a number of circular tubes and, in one model, an outer frame.

The Universal grille is available in three models: MFA, UFA and UFK.

MFA is designed for mounting in floors, window sills and walls,and has an outer frame profile that can be selected in three different versions: A, B or C.

UFA is designed for floor and window sills installations and does not have a outer frame profile.

UFK is designed for mounting in floors and does not have an outer frame profile but is supplied with a frame for cementing to the floor. MFA and UFA are available in three different slot widths: 5, 10 and14 mm. UFK is available with two slot widths: 10 and 14 mm.

The grille is made from extruded aluminium profiles and is anodised/electroplated. The diffuser is available in six alternative standard colours (powder coating).
