Ventilation grille EUROPLAST ND10FVA 148×153 mm for DN100 duct with built-in check valve

Plastic ventilation grille EUROPLAST ND10FVA sized 148×153 mm is designed for connection to DN100 round ducts. The grille integrates a built-in check valve that prevents backflow and unwanted drafts while maintaining unobtrusive appearance. Its compact rectangular frame allows installation in walls or ceilings to cover the duct outlet, provide airflow control and deliver a tidy finish. Lightweight construction and smooth surfaces make the grille easy to install and maintain in residential and commercial interiors.

Advantages

The grille combines a frame sized 148×153 mm with an outlet suitable for DN100 circular ducts, offering a compact solution where space around the duct opening is limited. The integrated check valve provides reliable backflow protection without adding external components, reducing installation complexity. Being made of plastic, the product is corrosion-resistant, lightweight and simple to clean. The unobtrusive design ensures the grille blends with a variety of interior finishes while securing consistent airflow management.

How to use

Position the grille so the outlet aligns with the DN100 duct end and secure the frame to the wall or ceiling using appropriate fasteners for the substrate. Ensure the check valve is installed in the correct orientation according to airflow direction. After fastening, verify that the valve moves freely and that the grille sits flush with the surrounding surface. Clean the grille periodically with a damp cloth to remove dust and maintain unobstructed airflow.

Usage recommendations

For reliable performance, confirm duct diameter compatibility before installation and use corrosion-resistant screws or anchors suitable for the mounting surface. Avoid painting the valve area to preserve free movement. Inspect the check valve during regular maintenance intervals to ensure it closes properly and prevents reverse airflow.
