SIGMA 125 WHITE

SIGMA 125 WHITE is a stainless steel design gravity shutter designed to be mounted on house facades, walls or plaster, for air extraction especially from high-capacity hoods and fans. The Sigma gravity louvre shutter with circular connection is insulated and sealed, designed for higher pressure fan applications. The Sigma residential overpressure damper features a unique patented design.

The square grille plate is fitted with two louvres, a dripcatcher and a secondary insulated butterfly damper in the circular spigot in the wall. This combination of non-return dampers and insulation ensures a high airtightness of the duct as well as a reduction in heat loss when the damper is automatically closed. The gravity shutter with modern design is made of stainless steel painted in white (RAL 9010). Patent N°: 004028397-0001.
