Belt Driven Fan Vs Electric Fan

When a vehicle is moving a pusher fan can obstruct airflow due to its positioning in front of the radiator.

Belt driven fan vs electric fan.

Generally such fans are cheaper than direct drive fans of comparable size. Are electric fans the best way to go. Belt drive fan from commercial electric is a prudent choice for just about any industrial application. Where people and machines need to be kept cool in the factory warehouse or other large area or to keep animals comfortable and remove stale air and odors from the barn look to this rugged power packed air circulator.

Fitment some electric fans have thin profiles so they can fit where belt driven sometimes can t. We invented the flex fan and at flex a lite we ve expanded our belt driven fan line to include a lower profile fan for street rod applications a 7 blade version for higher static pressure and light weight and all steel fans to meet the needs of the oval track racing market. For fan sizes below 42 a direct drive fan can be configured to cost the same or less than a belt drive fan for most combinations of airflow and static pressure. Is the added stress to the charging system out weigh the lose of hp from the mechanical fan.

Electrical fans can either push air through the radiator or pull air through it. This is because of the fact that the amount of friction is greatly reduced in case of this fan when the fan is operating. Maximum power and fuel economy no parasitic power loss. More often than not the maintenance cost of this kind of fan is also comparatively lower.

I have a mechanical belt driven fan on my truck now but the dern thing sounds like a c130 driving down the road from all the fan noise. A pusher fan sits in front of the radiator. Belt driven fans offer greater flexibility in terms of rpm speed. When airflow specifications require a fan greater than 42 in diameter a belt direct fan may have an advantage due to motor costs.

Select an electric fan for. One major downside of belt driven fans is parasitic loss. Unlike the belt driven fans in case of a direct drive fan there is lesser energy loss. Conversely electric fans move more air than belt driven fans at engine speeds below 2 400 rpm in typical applications.

My truck is used mostly for towing and local driving. When choosing an electric fan here are a few factors you should be aware of. Our fan construction and designs have been proven on and off the track for 50 years. In a belt driven configuration the motor exists independently of the fan blades and at least one belt sometimes more connects the motor to the fan s moving parts.
