There are a wide variety of commercial exhaust fans on the market today. From large commercial applications such as kitchen hood systems for restaurants to silent airflow systems that barely make a sound during use.
A commercial kitchen exhaust system, usually made of stainless steel, can cost several thousand pounds to buy and install. You can also look for the best Australian made inline centrifugal fans for your commercial kitchen.

Large ventilation wicks through a wall-mounted hood fan may be suitable for small hot food stores such as toast and bacon sandwich shops.
Commercial kitchen in-line exhaust fans are present which are fixed over the ceiling, often some distance from the room where they are actually expelling air.
They are connected to the ventilation openings in the ceiling via air ducts, which are then connected to an internal fan and then exhaust air through several channels to the louvers on the outer wall.
There is more to consider when buying a commercial fan than when buying a home fan. The reason is that while home fans are inexpensive to buy and install, and cheap to replace if they break down, the same is not true for commercial exhaust systems.
Most large commercial fan installations cost several thousand and require professional installation. So given the investment, you may make in one, you need to be purchasing with a reliable supplier, as you may be placing it in an atmosphere where you may have to stop work if the extractor fan system crashes down, such as in a commercial kitchen.
In that case, you should know that someone can come out very quickly and fix your reach hood. If you have to close your kitchen, you will lose money until it's made.
So you need to do some research for the company you buy the fan from and make sure they provide a fast call out and have enough spare parts.
