The Reversed series axial flow fans are available in a wide range of application including all Agricultural machinery,like Cotton pickers / Wheat Harvester,It uses changing hydraulic pressure to change the direction of rotation of the blades.When the agricultural machinery cooling water tank is full of grains or debris, reverse blowing can clear the debris in time to increase heat dissipation and prevent the tank from overheating and damaging the engine
Introduction ▼
Designed for agricultural machinery, mining equipment, crushers, and all power machinery operating in dusty conditions, the RS Fan revolutionizes engine cooling and maintenance. When engines run in environments filled with rice husks, straw, wood chips, or dust, traditional radiators quickly clog, leading to reduced cooling efficiency, higher fuel consumption, and even engine failure. Conventional cleaning methods—such as manual labor or compressed air—are time-consuming, inefficient, and often impractical.
UTEK-DELE hydraulic fan solves this problem effortlessly! Installed between the engine and radiator, it operates normally under engine belt drive for cooling. Its patented 180° reversible blades (pneumatic/hydraulic-controlled) allow instant airflow reversal with just a push of a button, blasting away dust buildup without stopping work. Once released, the fan resumes normal operation. For added convenience, an optional timer enables fully automated cleaning cycles.
Just use hydraulic drive ▼
The RS-A series fan has small air volume and small space after reversing.
After the fan is pressurized, the blade is turned over, the Angle is changed from the rated Angle to 0 degrees, and then it is transformed to the Angle after the reversal, thus reversing.
The fan reversing depends on the back of the work, the rear wind is small, the reversing process is driven by hydraulic pressure, there are 6 leaves 8 leaves and other models can be selected.
The hydraulic fan is divided into three levels:
 Diameter 450-650mm |  Diameter 650-842mm |  Diameter 800-1250mm |
Diameter: 450mm to 1250mm  Pull wind | Angle change: From +35°to -35°  Push wind |

FAQ ▼
Q: Are almost all fans replaceable?A: Yes.
Q: Can they be fitted?A: We can machine the connection holes and bushings, so they can definitely be fitted.
Q: Is it safe to use?A: We will balance and match the angle to the power speed.
Q: Is it possible to replace only the blades?A: No problem, the design is exactly the same.
