Drive Type
When Each One Is The Better Fit
At the same diameter both ranges move the same volume of air. The choice comes down to noise, maintenance and the environment the fan has to live in.
Choose Geared When…
- The building is an industrial one and 60 – 65 dB is well below the ambient noise floor
- You want the proven German gear motor drive train — Nord or SEW
- You need an 18 ft fan, which is offered only in the geared range
- A scheduled gear oil change fits comfortably into your existing maintenance routine
- Robustness under heavy dust, heat and continuous duty is the top priority
Choose Gearless When…
- Noise matters — below 40 dB keeps speech, music and acoustics unaffected
- The floor below is food, pharma or public-facing, and gear oil overhead is a question you would rather not answer
- You want the shortest maintenance schedule — no gearbox, no oil, fewer wear parts
- Motor power draw matters: 0.35 – 1.2 KW against 0.75 – 1.5 KW geared
- The fan is visible in a designed interior and the glossy black finish reads better
Any Brand
Comparing Us With Someone Else?
Send us the other brand's technical datasheet. We will put it side by side with the equivalent Austar model — spec for spec, on the same rows — and send back a written comparison summary so you can decide on the numbers rather than on the sales pitch.
- Diameter, air delivery, motor make and rating, speed range, coverage
- Hub, blade and structure specification, and what each is tested to
- Safety provisions, certification and what the warranty actually covers
- Where the other brand is the better fit, if it is — we will say so
No datasheet to hand?
Talk to a sales executive on +91 98245 95566 and we will work from whatever you have — a quotation, a model number, or a photograph of the nameplate.
