Ventilation grille with hood airRoxy fi 100 brown — airRoxy 02-501BR

The airRoxy fi 100 brown wall ventilation grille with hood is designed for terminating 100 mm ventilation ducts on exterior walls. This compact external vent fits within common residential and light-commercial ventilation systems to serve as an exhaust or supply-air outlet. The integrated hood shields the duct opening from rain and snow while reducing the risk of backflow and ingress of debris, maintaining airflow performance for kitchen and bathroom extractors or fresh-air inlets.

Advantages

The product combines a simple, low-profile design with a weather-protective hood to ensure reliable outdoor termination of round ducts. The brown finish is intended to blend with façades and window frames, while the hood reduces direct wind impact and limits entry of small objects. Constructed for straightforward wall mounting, the grille supports consistent airflow and reduces maintenance needs compared with unprotected duct ends.

Suitable for

• Exhaust outlets for kitchen and bathroom fans with 100 mm ducts
• Supply-air terminations for small ventilation systems
• Replacement of open or damaged external duct ends
• Residential and light commercial building façades

Key specifications

• Duct connection diameter: 100 mm
• External hood for weather protection and limited backflow prevention
• Colour: brown
• Material: durable exterior-grade plastic
• Wall-mount design for through-wall termination

How to use

Cut or prepare a 100 mm diameter opening through the wall or existing duct termination. Insert the grille so the circular connection aligns with the duct; fasten the unit to the wall using appropriate screws and anchors for the wall material. Ensure an airtight connection between the grille and the internal duct using a friction fit or suitable sealant to prevent leaks. Verify unobstructed airflow and that the hood is oriented correctly to shield the opening from prevailing weather.

Usage recommendations

Inspect the grille periodically for accumulated debris or insect nests and remove any blockages. For best performance, use with ducts of matching diameter and maintain internal duct cleanliness; in coastal or chemically aggressive environments, select suitable fasteners and consider additional UV-resistant sealants to prolong service life.
