The RED-PF perforated cylindrical grille for circular ducts is installed in an opening of a round duct. It is made of galvanized steel with a polymer coating. It can additionally be fitted with an airflow damper or flow regulator. The blade orientation (vertical or horizontal) can be changed on request.

These models are used for installation in circular ducts of supply and exhaust ventilation systems and require no adapters. This makes installation quick and hassle-free. Thanks to their attractive appearance, they blend seamlessly into any design.

Design: The RED-TsR-PF perforated grille for circular ducts consists of a frame and a perforated steel panel. The frame edges are bent to follow the contour of the duct on which the grille is mounted.

Finish: Powder coating is applied at the factory in colours from the international RAL scale. Standard colour: white. The polyester coating reliably protects the steel against oxidation.

Size: Minimum recommended size 200x100 mm. Maximum recommended size 600x300 mm. The height of the opening for the grille must not exceed 75% of the duct diameter. Larger sizes can be manufactured with additional reinforcement. Please contact our managers for details.

Installation: The grille is fixed directly to the circular duct with self-tapping screws.
