Inline Duct Exhaust Fan – DP-B045-AU

The Arklyfe Inline Duct Exhaust Fan DP-B045-AU is the flagship of the Arklyfe inline duct fan range: the maximum-airflow model in the B-series, built around a Ø150 duct for the AU bathrooms, laundries and small-commercial spaces where extraction has to be measurably faster than any standard residential fan can deliver. It is positioned for the demanding-airflow scenarios: triple-shower commercial change rooms, oversized family laundries running multiple cycles daily, basement bathrooms without external windows, indoor pool change rooms, and any space where chronic moisture damage has not been solved by smaller fans. Shipped from Melbourne for Australian 240V mains.

Compared to the DP-B033 at the same Ø150 duct diameter, the DP-B045 is engineered to push more cubic metres per minute through that same duct opening. The difference matters in spaces where the moisture load genuinely exceeds what a residential-grade fan was designed for (restaurant bathrooms, gym change rooms, indoor pool wet areas) and where the existing fan obviously isn't keeping up. Most AU residential bathrooms don't need this much airflow; the buyers who do, know it. For everyone else, the DP-B033 is the right step in the B-series.

Inline ducted installation keeps the fan body out of the visible bathroom, with the motor and housing sitting in the ceiling cavity or duct run and only a clean ceiling vent showing. The motor is sized for the higher airflow without crossing into the noise level that would make it unusable in residential settings. It stays comfortable to run multi-cycle every day. For the highest-airflow inline scenarios specified in the Arklyfe range, this is the model.
