Runs on Solar or Battery · 3× Less Power than AC Fans · Zero Electricity Cost · Ideal for Solar Homes, Dairy & Poultry
DC fans use permanent magnet motors instead of AC coil windings for magnetic induction. Permanent magnets are far more efficient — a 12W DC fan delivers the same air output as a 25–30W AC table fan. This is not a marketing claim; it is basic motor physics. The result: you get the same cooling at one-third the electricity cost, and the fan runs for many more hours per battery charge.
DC fans also have longer service life than AC fans because there is no complex coil winding mechanism that can fail or overheat. Fewer parts, less heat, longer life.
| Feature | DC Fan (Thumba) | Standard AC Fan |
|---|---|---|
| Table fan power | 12 Watt | 25–30 Watt |
| Pedestal fan power | 18 Watt | 40 Watt |
| Ceiling fan power | 28–32 Watt | 70–80 Watt |
| Runs on solar / battery | Yes — 12V direct | No — needs inverter |
| Electricity cost | Zero (solar) | Ongoing EB bill |
| Motor type | Permanent magnet | AC coil winding |
| Service life | Longer — fewer parts | Coil failure common |
| Best for | Solar homes, dairy, poultry, farms | Grid-connected only |
All models operate on 12V DC — compatible with any 12V solar panel or battery system.
Thumba DC fan prices vary by model — table fan (12W), pedestal fan (18W) and ceiling fan (28–32W) are all available. Call us on +91 98433 35703 or WhatsApp for current pricing. Price depends on model and quantity required.
A DC fan uses a permanent magnet motor instead of an AC coil winding. This makes it approximately 3 times more power-efficient — a 12W DC table fan gives the same air output as a 25–30W AC fan. DC fans also run directly on 12V solar panels or batteries, making them ideal for solar and off-grid installations. They have a longer service life because there is no coil winding mechanism to fail.
On a fully charged 150Ah battery: DC table fan (12W) runs approximately 120 hours, pedestal fan (18W) approximately 80 hours, ceiling fan (28–32W) approximately 50 hours. On a 15Ah battery: table fan about 12 hours, pedestal fan about 7 hours. Actual runtime depends on battery age and ambient conditions.
Yes — any 12V solar panel with sufficient wattage can power a DC fan directly during daylight. For night use, connect the panel to a 12V battery; the fan runs from the battery at night and the panel charges it during the day. This makes DC fans completely free to run after the one-time installation cost.
The DC ceiling fan (28–32W) is the best choice for large open spaces like dairy sheds and poultry houses — it can be mounted at height to circulate air across the full area. For smaller stalls or personal spots, the table fan (12W) or pedestal fan (18W) work well. All models run on 12V solar or battery with zero electricity cost.
All standard models run on 12V DC, compatible with 12V solar panels, inverter batteries, and solar home systems. The ceiling fan is also available in 24V DC on request, suited to larger solar battery bank setups.
