Vento Midi Maxi Duo High Rise Wall Mount Vent Kit - 500mm Long

Internal installation solution for flats, apartments, and high rise buildings

Installing ventilation in multi-storey buildings or areas with limited external access often involves scaffolding, increased costs, and safety risks. The Blauberg VENTO High-Rise External Wall Kit offers a practical, safe alternative designed specifically for internal installation of VENTO Single Room Heat Recovery Units (MAXI, MIDI, DUO).

Why use the VENTO high rise external wall kit?

The ventilation kit provides an effective solution for fitting external vents from within the property itself, removing the need for external scaffolding or ladders. This approach significantly simplifies installation of Vento single room heat recovery units in apartments, flats, and other multi-storey properties, particularly in urban settings or where external access is restricted.

Local authorities, housing associations, landlords, and homeowners dealing with retrofit projects, social housing upgrades, or compliance issues (such as Awaab’s Law requirements) will find this kit a straightforward, cost-effective ventilation solution.

How it works

Installation is straightforward:

• Drill a 180mm hole through the external wall (standard size for VENTO MAXI, MIDI, DUO).
• Insert the pre-fitted external hood and silicone sealing ring from inside the property.
• Pull gently back to create a secure, weatherproof fit.
• Insert the supplied rigid duct (160mm) at a slight downward angle for drainage.
• Secure with foam wedges and standard mounting foam or sealant.

No external scaffolding or specialist height equipment required.

This wall kit integrates seamlessly with Blauberg’s existing VENTO single room heat recovery units:
