Product Description

Internal steel grilles of the JR series are designed for air supply and exhaust in residential, administrative, and industrial premises. Their main feature is movable blades (louvers), which allow manual adjustment of the airflow direction, customizing the microclimate in a specific zone.

The grilles are powder-coated in standard white color (RAL 9010), making them versatile for most interiors. The models are compatible with rectangular air ducts, static pressure plenums, or can be mounted directly into building wall openings.

Model Range and Features

• JR 3/2 (Single deflection): Equipped with a single row of horizontal adjustable blades. Allow adjusting the airflow up or down (vertically). Depth of the product without damper — 30 mm.
• JR 7/2 (Double deflection): Have two rows of blades — horizontal and vertical. This allows directing the air jet in any direction (up-down and left-right), providing maximum control over aerodynamics. Depth of the product without damper — 50 mm.
• Volume adjustment (Option): The grille itself only changes the flow direction. To adjust the air volume (balancing), an additional flow control damper (Opposed Blade Damper) must be purchased, which is installed on the rear side.
• Materials: The casing and blades are made of durable steel. Upon special order, manufacturing from aluminum or stainless steel is possible, as well as painting in any color from the RAL palette.
