Description and manufacturing

Purpose

Round diffusers are used in supply and exhaust ventilation. They are designed for low- and medium-pressure systems, as well as for supply and exhaust air conditioning systems, and can operate with both constant and variable airflow.

Design and materials

The housing and the inner part of the diffuser are made of high-quality aluminium, and the airflow control damper is made of plastic.

They are powder coated in RAL 9016, which provides reliable protection against adverse environmental factors and prevents premature wear of the product. The diffuser is moisture-resistant and easy to clean of dust.

Manufacturing

The series includes standard diameters only: d150, d200, d250, d300, d350.

Ordering example and installation

Round diffuser NCD-150 (RAL 9016) – connection diameter 149 mm, overall outer dimension 257 mm, white.

Options

Available with a VD plenum box made of galvanised steel (with side or axial connection to a round or rectangular duct).
