Protection grid
The HVAC protective grilles are most often used to protect a fan against an ingress of foreign bodies, but also to terminate the ventilation ducts, or directly for the installation on the suction or discharge of the fan. Our range of protective grilles usually includes grilles standardized by the manufacturers for specific fans. The protective grilles are designed for both circular and four-sided ducts.
