Spiro Grilles Spiro-G horizontal slats, Rec Indovent

Spiro grilles for mounting directly in a duct without sockets and mounting frames. Spiro-G is intended for large premises where the spiro duct is visibly mounted, eg warehouse / factory halls, workshops, sports halls, etc. Fits spiro ducts Ø200 - 800mm. Spiro-G is made of galvanized sheet steel. The flange is rounded in a radius corresponding to the spiro dimension, the back is fitted with a rubber strip that seals against the duct. Through the grille's adjustable slats the air can be guided in the desired direction. Horizontal slats (HS) control the air, upwards - downwards. Vertical slats (VS), control the air to the sides. Height and width are nominal dimensions and indicate the dimensions for drilling holes.
NOTE! The height of the grid should be less than half the diameter of the spiral tube.
