Air intake vent Heatpex AN 125 ARIA ADUROADURO by Heatpex

Heatpex AN 125 ARIA ADUROADURO by Heatpex is an external air intake vent intended for ventilation systems that require a protected opening to admit fresh outside air into ductwork. The unit is shaped and sized to fit standard 125 mm ducts and is designed for mounting on external walls. Its form provides protection from weather and debris while allowing continuous airflow into residential and light commercial ventilation installations.

Advantages

The Heatpex AN 125 ARIA ADUROADURO combines a compact footprint with a profile that reduces rain and wind ingress, maintaining airflow performance for supply and balanced ventilation systems. Its materials and construction are chosen to resist outdoor conditions and to simplify mounting on masonry or panel walls. The grille design limits the entry of leaves, insects and larger particles without significantly increasing resistance to airflow.

Suitable for

• Residential supply and exhaust ventilation systems with 125 mm duct connections
• Small commercial or office ventilation installations requiring an external intake grille
• Renovation projects where an exterior-mounted fresh air inlet is needed
• Situations where basic protection against rain, debris and insects is required

When it may not be suitable

This external intake vent is not intended for use with high-capacity industrial ventilation where larger diameters or higher airflow rates are required. It also does not replace weatherproofing measures for locations exposed to severe driving rain, heavy snow accumulation, or salt spray; in such conditions additional protective measures or specialized models should be considered.

Key specifications

• Nominal duct connection diameter: 125 mm
• Application: external air intake for ventilation systems
• Mounting: external wall installation
• Function: admits fresh air while reducing ingress of rain, debris and insects
• Typical use environments: residential and light commercial buildings

How to use

Install the Heatpex AN 125 ARIA ADUROADURO into an appropriately sized opening in the external wall so the duct aligns with the 125 mm connection. Secure the unit using appropriate fasteners for the wall material and seal the perimeter to prevent drafts and water penetration. Connect the internal ducting to the intake spigot, ensuring a continuous, unobstructed airflow path. Periodically inspect the grille for blockages and clean as needed to preserve ventilation efficiency.

What to consider before purchase

• Verify that your ventilation duct diameter is 125 mm and that wall thickness is compatible with the unit depth
• Consider the local climate and whether additional weather protection is required
• Confirm mounting surface and choose appropriate fasteners and sealants for masonry, brick or panel walls
• Plan access for periodic cleaning and inspection of the external grille

Usage recommendations

For consistent performance, install the intake at a location sheltered from prevailing winds and heavy splash zones, maintain a clear area around the grille, and inspect the vent at least once per season to remove debris. If the installation is in an exposed or coastal location, consider corrosion-resistant fixing methods and additional weatherproofing.
