Introduction
The Vent-Axia HR500IP unit is designed for mounting in internal walls for installations
using ducted extraction and fresh air supply. Air movement is achieved by using in-line
duct fans or wall mounted units to suit the length and configuration of ducting systems.
The unit is compatible with Ø300mm flexible duct and is ideally suited for use with in-line
fans and external wall louvres.
Concentric reducers are available to convert inlet and exhaust spigots to 250mm or
200mm diameter for use with alternative sized fans and ducting if required.
