Increasing efficiency with Flexxaire's variable air flow fan


Flexxaire’s variable air flow fan is seeing some modifications for 2019/2020.

Starting with the smallest series fans in 2019, the company is introducing a wide blade for more surface area, and thus greater air flow. For 2020, the change will be applied to the 1000 Series as well, says Frank Rodrigues, dealer accounts manager, in the following video, filmed at Agri-Trade at Red Deer, Alta.

The fan, which comes standard in many machines now, enables operators to work through the time they’d otherwise have to stop to clean the radiator.

“So with a two-position fan, you’re basically running your machine — and it can be all sorts of different types of machines from agriculture, construction, etc. — and with the timer it will automatically reverse the airflow and clean out the radiator so the operator doesn’t actually ever have to stop,” says Rodrigues.

Using monitored variables, the system can adjust the pitch of the blade to maintain optimum engine temperature, improving overall efficiency.

“The biggest thing with the airflow management system like this is that you’re going to reduce your fuel consumption, you’re also going to reduce noise levels because in a lot of cases you’re not pushing as much air…, but you’re also being more efficient overall because you’re not having to stop.”
