Comfort, efficiency, durability

The PRD system is energy efficient and easy to maintain. Made of brushed steel, PRD’s precise laser-cut perforations provide a comfortable air movement with low temperature differences and low noise.

The PRD’s high induction air diffusion ensures homogeneity of both temperature and humidity, ensuring occupant comfort. And the sleek powder-coated finish complements any décor.

High induction air diffusion

Using our unique Prihoda AirTailor® software, we take your project requirements and design a complete high-induction diffuser system tailored to your specific application.

PRD Perforated Duct Diffusers are constructed in diameters ranging from 8 inches (200 mm) up to 38 inches (965 mm). Duct sections are assembled using discreet sleeves with integrated silicone gaskets, to ensure a proper seal and circular integrity of the duct. Matching passive duct sections without holes and multiple fittings are also available, to ensure the uniformity of the entire duct network.
