Square Sensor Exhaust Fan-SEPD150MH-220

The Arklyfe Square Sensor Exhaust Fan SEPD150MH-220 is the smart-automation flagship of the Arklyfe exhaust-fan range — a sensor-driven fan that turns itself on and off based on what the bathroom actually needs, not what someone remembers to do at the wall switch. Built around a humidity sensor and a motion sensor, it ventilates automatically when moisture levels rise after a shower or when someone enters the bathroom, then runs down to off without a manual override. Shipped from Melbourne for Australian 240V mains.

The automation logic is what justifies the price step over a standard fan. Most AU bathroom exhaust fans run for far longer than they need to (when someone forgets to switch them off after leaving) or far shorter than they need to (when someone switches them off as they leave but moisture remains in the room). The humidity sensor handles both: it triggers ventilation when relative humidity crosses a setpoint, then keeps running until the moisture has actually cleared, regardless of whether anyone is still in the room. The motion sensor adds entry-triggered ventilation for short visits where humidity hasn't built up yet.

The hardware backs up the automation. A DC motor runs more efficiently, more quietly and with longer service life than the AC motors in standard fans — relevant when the fan is running multiple cycles per day under sensor control. Lower noise keeps the automatic operation from disturbing sleep or daytime calls, and the longer lifespan matches the higher daily run-time the sensor logic produces. For AU bathrooms with mould and moisture problems that aren't getting solved by the existing fan or by user discipline, this is the right answer.
