Brushless DC twin motors
Quieter, more efficient and longer-lived than the AC motors on entry models — the argument that wins against cheaper ceiling units.
Our top ceiling model, built around brushless DC twin motors — measurably quieter and more efficient than the AC motors used on entry units, with a longer service life. Auto-swing louvres sweep the air across the room instead of blowing one hot spot, and plasma sterilisation tackles bacteria and odour. 3,000 W total, 9-key wireless remote, 24 W LED, night light and drying mode.
MOQ 100 pcs for custom panel colour, pattern and logo · 1,000 pcs for custom packaging. Samples from 1 pc — the sample price is higher than the bulk price, and we refund the difference once you place a bulk order within 30 days of receiving the sample. Prices are quoted per order, EXW Shanghai — tell us your quantity and destination port and we will reply within one working day.
Why this model
Six things buyers ask about first — every unit is function-tested before packing.
Quieter, more efficient and longer-lived than the AC motors on entry models — the argument that wins against cheaper ceiling units.
Wide-angle powered louvres sweep the airflow across the room, replacing the hot spot and direct-blow discomfort of fixed-grille heaters.
Plasma module works on airborne bacteria and odour — a feature buyers in humid markets specifically ask for.
Low-level night light for the bathroom, plus a drying cycle that clears humidity after a shower.
Every function — including temperature setting and timer — is on the remote; no wall switch and no extra wiring.
Deeper body than the entry models to house the DC motors and swing mechanism; same standard ceiling cut-out.
