Vent-Axia Quadra and Centrif Duo Plus Filter 439927

Vent-Axia 439927 — Replacement Filter for Lo-Carbon Quadra and Centrif Duo Plus Extractor Fans, 225×160mm.

The Vent-Axia 439927 is an optional replacement filter set designed for use with the Vent-Axia Lo-Carbon Quadra and Centrif Duo Plus extractor fans. Fitting an inlet filter to these fans prevents airborne dust and debris from accumulating on the fan internals — protecting the motor and impeller from particle build-up that would otherwise reduce airflow performance and shorten the service life of the unit. Replacing the filter at regular intervals maintains the ventilation performance the fan was installed to deliver.

Protects Fan Performance Over Time

Dust and airborne particles drawn through an unfiltered fan can coat the impeller blades and motor housing, gradually reducing the effective airflow rate without any obvious visible warning. A correctly fitted and maintained filter intercepts that particulate before it reaches the fan internals, keeping the impeller clean and the motor running at its designed operating temperature. For social housing and residential installations where fans may run continuously, regular filter replacement is a straightforward way to maintain Building Regulations compliance and extend the working life of the installed fan.

Compatible with Lo-Carbon Quadra and Centrif Duo Plus

The 439927 filter is an optional accessory that fits directly into compatible Vent-Axia Lo-Carbon Quadra and Centrif Duo Plus fans. At 225×160mm it is sized to suit the inlet aperture of these models. Vent-Axia's own guidance recommends periodic filter inspection and replacement as part of routine fan maintenance — the replacement interval will depend on the dust levels in the installation environment.
