        Airvent | ECHB-150N Ceiling Exhaust Fan 150mm EC Motor | IPX4 Backdraft Damper

        The Airvent ECHB-150N is a 150mm ceiling-mounted exhaust fan with an EC motor and an integrated backdraft damper. It moves 105 litres per second against 83 Pa of static pressure, drawing 0.25A from a 240V single-phase supply. The ECHB-150N installs into a 279mm ceiling cut-out and is rated IPX4. It arrives with a 1.2 metre lead and a two-pin plug fitted.

        An exhaust fan quoted at free-delivery airflow disappoints once it is connected to six metres of flexible ducting and an eave terminal. The ECHB-150N is rated at 105 L/s against 83 Pa of static pressure, representing a duty point rather than an unrestricted open-outlet figure. The centrifugal impeller sustains that volume where an axial impeller would stall. An integrated backdraft damper prevents external air migrating back along the duct once the fan stops.

        For a bathroom retrofit, the 279mm cut-out generally corresponds to the opening left by an older ceiling fan. The EC motor draws 0.25A at 240V, so the fan accommodates an existing circuit comfortably. 36 dBA at 3 metres keeps operation quiet enough that occupants leave it running, which is the entire purpose of a moisture extract. A 1.2 metre lead and plug complete the connection at a ceiling socket.

        Features

        • 105 L/s at 83 Pa — the ECHB-150N is rated at 105 litres per second against 83 Pa of static pressure at its duty point.
        • EC motor — an electronically commutated motor rated 0.038kW, drawing 0.25A at 240V single phase, 50Hz.
        • Centrifugal impeller — a centrifugal impeller sustains airflow against duct resistance where an axial impeller loses it.
        • 36 dBA at 3 metres — total sound pressure of 36 dBA at 3 metres, quoted as an in-duct inlet figure.
        • Integrated backdraft damper — the damper closes when the fan stops, blocking return air down the duct.
        • 150mm outlet spigot — a 150mm spigot suits standard 150mm flexible or rigid duct.
        • 279mm cut-out, 329mm grille — the ECHB-150N housing installs into a 279mm cut-out, covered by a 329mm round white grille.
        • IPX4 rated — rated IPX4 against splashing water, which suits bathroom and laundry ceilings.
        • 1.2 metre lead and two-pin plug — supplied pre-terminated with a 1.2 metre lead and a two-pin plug.
        • Adjustable airflow — airflow is adjustable for commissioning and air balancing after installation.
        • Section J compliance stated — the manufacturer's technical data states compliance with 2019 and 2022 NCC/BCA Section J.
        • Ceiling mount only — the ECHB-150N is a ceiling extractor supplied with its fan housing, not a wall or window fan.

        Where to use

        • Bathrooms and ensuites — the ECHB-150N extracts moisture from wet areas through a ducted ceiling run.
        • Laundries — steam and humidity extraction where a ducted ceiling fan suits the layout.
        • Kitchens and butler's pantries — odour and steam removal on a general extract rather than a rangehood duty.
        • Retrofit fan replacements — the ECHB-150N cut-out often matches or adapts to an existing ceiling opening.
        • Longer duct runs — the centrifugal impeller and 83 Pa duty rating suit runs with bends and an eave or roof terminal.
        • Light commercial amenities — office and amenity extract runs on 150mm duct where a ceiling fan is specified.

        The ECHB-150N is a ceiling extractor and is not designed for wall or window installation. IPX4 covers splashing water rather than immersion or direct spray, so check the zone requirements before positioning it over a shower enclosure. Airflow depends on duct length, bends, and terminal type, so a long or restricted run delivers less than the 105 L/s duty rating.

        (ECHB-150N)

        It is used to remove steam, moisture and odours from areas like bathrooms, laundries and kitchens.

        Yes. The high airflow makes it suitable for bigger spaces or areas with heavy moisture.

        It stops outside air coming back through the duct when the fan is off.

        Yes. The IPX4 rating makes it suitable for moisture-prone areas.

        That depends on how it is wired, but it can be set up with timers or switches by an electrician.

        Yes. Sparky Direct stocks the Airvent ECHB-150N with fast dispatch and delivery across Australia.
