Four functions, one ceiling panel
Heating, ventilation, blow and LED lighting share a single 300 × 600 mm panel — one cut-out in the ceiling instead of three appliances.
A hard-wearing ceiling unit for the everyday bathroom: 2,450 W total (2,400 W heating plus 40 W ventilation / blow) and an 18 W LED panel in a standard 300 × 600 mm module. The dual-duct design with an encapsulated ball-bearing motor keeps airflow strong and noise low, and a classic four-key piano switch means nothing to learn and little to fail. IPX2 for splash-prone rooms.
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.
Heating, ventilation, blow and LED lighting share a single 300 × 600 mm panel — one cut-out in the ceiling instead of three appliances.
Grille layout can be supplied in more than one configuration to match the ceiling grid you already buy — tell us which one you want and we build to it.
Separate intake and exhaust ducts route air across the whole panel, so the room warms evenly instead of one hotspot under the unit.
The motor is sealed against bathroom humidity — the usual cause of short motor life in this product category.
Four-key mechanical switch, black or white. No board, no pairing, nothing to misconfigure — the most reliable control we ship.
Drops straight into the common 300 × 600 mm integrated ceiling grid. 85 mm deep, 2.9 kg net — light enough for a single fitter.
