The NKSD-C swirl diffuser is designed for low- and medium pressure ventilation systems. A distinctive feature of this product is the outlet which swirls the incoming air to mix the indoor air volume with the fresh air stream. The swirl diffuser features adjustable plastic vanes (8 to 48 vanes, depending on the product type) to force a uniform and steady air stream. The product is easy to use and designed for installation on a plenum box.
It can be operated in steady and variable air flow systems. The swirl diffusers are mostly installed in ventilated industrial spaces and climate-controlled areas. The swirl diffuser is installed flush with the ceiling. When installed on the PRW plenum box, they provide a uniform air supply, while an insulated version of the plenum box reduces the ductwork and air noise level. The NKSD-C swirl diffusers come with installation screws.
