Fan systems
JKF Fans - Proven performance across industries
Fans with large effect
Resistance occurs in all forms of air transport due to friction which means that overall pressure is reduced in the flow direction. To effect and maintain air transport, pressure has to be increased at some stage to compensate for pressure loss. This is usually achieved in fan systems using radial and axial fans designed to boost air in the direction of the outlet.
A fan’s effect is always based on the actual volume flow through the inlet. If the volume flow is indicated at a temperature different than that of the fan in a given operating situation, it has to be corrected.
Motors and fans are usually supplied as a unit. JKF has designed its fans for optimal performance, and it is vital to select the right one for any given task. The speed at which the fan is to run can be seen from the graph for that fan. The power input depends on resistance in the system.
Types of impellers
There are many types of an impeller, each of which is designed for a given task:
Radial fan with P-impeller
Has flat backward-inclined blades and is designed for clean air transport. This type has the following properties:
- High efficiency
- Robust construction
- Only small variations in volume flow, if resistance fluctuates
Radial fan with T-impeller
Has backward-inclined blades and is designed for transport of a range of materials. This type has the following properties:
- Medium and high-pressure versions
- Robust construction
- High degree of self-cleaning
- Can handle large material volumes
- Special version available for transport of plastic and paper
Designed for industrial challenges
JKF fans are developed for use in a wide variety of industries - woodworking, food processing, metalworking, chemical production, agriculture, and many more. Depending on your specific application, JKF offers both direct and belt-driven fan systems designed to handle everything from clean air to abrasive and fibrous materials. Our fan range includes:
- JK-20D to JK-40D direct-driven fans - compact, efficient, perfect for clean air and light materials.
- JK-30K to JK-75K belt-driven fans - capable of moving large air volumes with high static pressure.
- T-200K/T-300K and T-200D/T-300D fans - built for concentrated material handling over long distances.
- High-capacity axial and radial fans transporting over 111,000 m³/h.
Each JKF fan is constructed from high-quality materials and engineered for long life, quiet operation, and low maintenance. Options include stainless steel components, explosion-proof (ATEX) motors, and acoustic booths for noise reduction.

Duct systems in stainless steel
Stainless steel ducts have many advantages
Today, stainless steel ducts are used more and more, not only for plants where it is required – e.g. in some food industries, but also in other plants where the customer requests the increased strength and durability. The stainless steel duct system has smoother surfaces and is more hard-wearing than the standard duct systems and the risk of peeling of galvanisation or coating has been eliminated. JKF's stainless steel duct system covers a wide range of ducts, bends, valves, transition pieces, jet caps etc.
The duct system can be used for all extraction purposes for transport of particles and air, and includes all the components needed for a complete extraction solution.
High-pressure extraction
Complete programme with large flexibility
JKF’s product programme for high pressure extraction is built up as a flexible system. It gives the possibility of individual building up and adjustment and contributes to ensure the right solution regardless industry.
