Ventilation grille/outlet with hood airRoxy KRATKA 170×170 mm, Ø125 mm, brown

airRoxy KRATKA 170×170 mm with a Ø125 mm duct connection is a ventilation grille/outlet with a protective hood designed for wall or ceiling exhaust terminations. The device creates an external finish for ventilation ducts, shielding the system from rain, snow and debris while allowing efficient air extraction. The compact 170×170 mm frame and round Ø125 mm spigot make it suitable for standard domestic and light commercial exhaust installations where a weather-protected outlet is required.

Advantages

The grille features a hooded external profile that prevents direct ingress of water and larger particles while permitting unrestricted airflow. Its dimensions and circular connection ensure compatibility with common Ø125 mm ducts and flexible pipes. The construction offers a neat, low-profile finish to external walls or ceilings and reduces the risk of blockages at the duct termination point. The brown color provides a discreet appearance on facades with warm or muted tones.

Suitable for

• Domestic bathroom and kitchen exhaust systems
• Ventilation outlets on exterior walls and soffits
• Light commercial exhaust installations in offices or small retail spaces
• Replacement or upgrade of existing Ø125 mm duct terminations

Key specifications

• Overall outer dimensions: 170 × 170 mm
• Duct connection (spigot) diameter: Ø125 mm
• Type: Ventilation grille/outlet with protective hood
• Mounting: Designed for wall or ceiling termination
• Finish: Brown color suitable for exterior facade matching

How to use

Mount the airRoxy KRATKA grille at the planned duct termination point on a prepared wall or soffit opening sized to accommodate the 170×170 mm frame and the Ø125 mm duct. Connect the ventilation duct or flexible hose over the spigot and secure with a clamp or appropriate sealant to ensure an airtight joint. Fasten the grille to the substrate using suitable screws or anchors for the wall material, ensuring the hood faces outward to shed water. Inspect the connection and test the exhaust system for consistent airflow after installation.

Usage recommendations

Use the grille in exterior locations protected from heavy mechanical impact and avoid installing in places prone to persistent water pooling. Periodically inspect the outlet for accumulated debris or bird nests and clear any obstructions to maintain airflow. For best performance, combine with appropriately sized ducts and ensure the ventilation fan or extractor is matched to the system resistance.
