Heatpex Czerpnia wypukła AN 160 – external air intake grille for ventilation

Heatpex Czerpnia wypukła AN 160 is an external air intake grille designed for connection to 160 mm ventilation ducting. The unit provides a weather-resistant point of air entry to mechanical or natural ventilation systems, featuring a convex profile that directs rain and debris away from the duct opening. Constructed for residential and light commercial applications, the grille helps introduce fresh outside air into duct networks while reducing the ingress of water and large particles.

Advantages

The grille’s convex geometry improves water run-off and reduces the risk of direct water penetration into the ventilation duct. Durable material and a compact design allow for straightforward installation on exterior walls and facades. The product is compatible with standard 160 mm duct runs and requires minimal maintenance; its shape discourages accumulation of leaves and larger debris, contributing to more reliable airflow and longer service intervals.

Suitable for

• Fresh air intake for residential ventilation systems
• Supply or make-up air for light commercial premises
• Connection to 160 mm circular ductwork
• Installation on exterior walls or service panels

Key specifications

• Connection diameter: 160 mm
• Design: convex / protruding profile to shed water and debris
• Intended use: external air intake for mechanical and natural ventilation
• Installation location: external wall-mounted
• Maintenance: low, requires occasional cleaning of the inlet opening

How to use

Mount the grille on the building exterior where it can be connected directly to a 160 mm circular duct. Ensure the surrounding area is free from obstructions that could restrict airflow. Secure the grille to a prepared opening with appropriate fasteners and seal the duct connection with suitable duct sealant or tape to prevent air leakage. Regularly inspect the inlet for accumulated debris and clean as needed to maintain unobstructed airflow.

Usage recommendations

Install the grille at a height and location that minimizes exposure to splash and heavy soiling. Use an insect screen or fine mesh inside the duct if there is a risk of small pests entering the system. Periodic visual checks after extreme weather will help ensure continued performance.
