Hand adjustable flap HKS 30

Variants of the Hand Adjustable Flap

The Hand Adjustable Flap HKS 30 is a high-quality solution for controlling airflows in ventilation systems. It is made of UV-resistant plastic and provides reliable sealing to prevent the ingress of cold air, dirt, and insects. This specific variant with a nominal diameter (NW) of 30 mm is ideal for applications requiring precise air control.

The HKS series includes several variants, including the Hand Adjustable Flap HKS 15 with a nominal diameter of 15 mm, HKS 20 with 20 mm, HKS 25 with 25 mm, HKS 35 with 35 mm, HKS 40 with 40 mm, HKS 45 with 45 mm, and HKS 50 with 50 mm. All models are designed to support a maximum airflow velocity of 12 m/s and are equipped with a pull cord mechanism for easy handling.

The choice of the right flap depends on various factors such as the size of the ventilation system and the specific requirements for air circulation.
