Plastic Ventilation Grilles with Mechanical Shutters NKM

Series Overview

The NKM series plastic ventilation grilles by Dospel (Poland) are designed for exhaust ventilation systems in residential and commercial premises. The horizontal louvres are manually controlled via two cords, allowing the grille to be fully opened or closed at any time — independently of the fan operation. A built-in insect mesh provides additional protection against insects and debris.
