Overlay adjustable grilles with one row of movable vanes are mounted directly on air ducts or building openings without deepening into the opening. This makes it easier to select and mount the grilles when the dimensions of the opening in the wall deviate from the designed ones. They are used in supply and exhaust ventilation systems and air conditioning systems.
The design of the Р-30-20 grilles is a U-shaped frame with individually adjustable rotary louvers installed in it, designed for air supply or exhaust in ventilation, air heating and air conditioning systems. They are made of high-quality aluminium profiles, which are covered with powder paint, which provides reliable protection against negative environmental factors and prevents premature wear of the product.
The standard color of painting is white, but at the customer request it is possible to paint in another color according to the RAL catalogue.
Fitting sizes LxH with 5mm steps.
For size L> 500mm, a dividing profile is used.

Р-30-20 * (RAL 9016) 300x200h – Screw mounting (mounting holes are located on the front side of the grille frame), white colour.
