HIDRIA Ventilating grilles, Ventilating valves

Ventilating grilles are designed for all types of lowpressureair conditioning, heating and ventilation systems with built in air flow and throw distance control as well as regulation of discharge angle. They can be used for both, supply air and exhaust air applications. Ventilating valves are designed to extract air from sanitary rooms and other premises and can be also used in low pressure airconditioning systems with air flow control.
