Other than the motor, there is no real difference. The motor on a three phase fan draws a lot less amps, thus requiring less power with the same size of motor, saving you money on your power bill. If you have access to three phase power, we recommend to use three phase if available.
Some market the turbofan as a superior product. Though it may outperform traditional styles fans at some static pressures, premium prices do not equal better value. It is always better to purchase a fan with more horsepower, as opposed to a fan with a turbo. However, turbofans are now available upon request.
Square-mount fans are called Full Centrifugal Fans and Round fans are called Inline Centrifugal. Square-mount fans are often designed for rocket style aeration and performance is dependant on static pressure. A larger, circle-mount fan with a transition, will effectively blow more air and is a more cost-effective option.
Inline centrifugal fans feature the best of both worlds. They work well in all levels of static pressure, come in standard mount sizes and are a better value for dollar spent.
Generally speaking, as a good ratio we recommend 1 hp for every 1,000 bushels. However, we have found that our customers who use our style of aeration systems on either the larger flat bottom bins or hopper bins are effectively using a 10Hp fan for up to 15,000 bushels and a 15hp fan for our 19,000-bushel bin package.
All Darmani fans are powder coated and painted either black or grey. This adds to the appearance as it matches the bin as well as eliminates potential rusting that will occur over time.
We now offer Inline Centrifugal (Round mount), Full Centrifugal (Square mount) and Turbofans. Generally, the most effective fan is the high-speed Inline Centrifugal fans.
For DARMANI Flat bottom bins, the aeration fan mounts directly onto the bin door thus eliminating the need for any adapters. The inner bracing of the door panel allows a fan up to 10 or 15hp to be mounted. The use of an air sock can allow the user to utilize one fan—moving it from one bin to another. For DARMANI Hopper bins, the aeration fan mounts directly the hopper inlet tube.
