FNH Pneumatic Brake

FNH Pneumatic Brake

The pneumatic brake FNH, is an efficient and reliable solution for tension control in industrial unwinding applications.

Its ability to continuous operation, its sensitivity in regulating air pressure and its heat dissipation capability make it an outstanding choice to ensure consistent performance and precise material handling in a variety of industries.

If you are looking for a reliable solution to control the unwind tension in your industrial processes, the FNH pneumatic brake is an option not to be overlooked.



What is the FNH pneumatic brake?


The FNH pneumatic brake is an essential solution in industrial applications where precise control of the unwinding tension is required.

This device is commonly used in paper, tissue, cable and other industries due to its ability to maintain a continuous friction with a minimal wear and tear and without generating annoying vibrations and noises.

Pneumatic brake components FNH

The FNH pneumatic brake consists mainly of two key elements: the static air chamber and the friction disc.

The static air chamber is responsible for supplying air to the system, allowing precise pressure control.

The friction disc is mounted on the shaft to be braked and is essential to generate the necessary resistance to control the unwinding tension.

Continuous operation and heat dissipation

One of the outstanding features of the FNH pneumatic brake is its ability to operate continuously.

This is made possible by the design of the brake disc, which incorporates a radiator with high heat dissipation capacity.

Efficient heat dissipation ensures consistent performance over time without overheating or loss of efficiency.

Sensitivity and regulation of air pressure

The FNH pneumatic brake is characterised by its high sensitivity and responsiveness. This is achieved by precisely regulating the air pressure supplied to the static chamber.

The ability to adjust air pressure enables optimum control of unwind tension, which is essential in applications where delicate handling of sensitive materials is required.

Industrial applications

This pneumatic brake finds its main application in industrial unwinders used in the paper, plastic, textile, graphic arts and other industries.

Its versatility and ability to maintain constant tension make it ideal for a wide variety of materials and industrial sectors. In addition, its light weight makes it easy to install and handle in different working environments.

Highlights of the FNH pneumatic brake


  • Self-supporting: The self-supporting design of the FNH pneumatic brake makes it easy to install and mount directly on the shaft where the coil or material to be unwound is located. This simplifies integration into industrial systems.
  • Static air chamber with radial air inlet: The static air chamber of the FNH brake has a radial air inlet, which allows an even air distribution and contributes to a precise and constant response in air pressure regulation.
  • Torque regulation by air pressure: One of the most outstanding advantages of the FNH brake is its ability to regulate the braking torque by adjusting the supplied air pressure. This allows precise control of the unwind tension according to the specific needs of the application.
  • High sensitivity: This means that it can be precisely adjusted to suit different types of materials and ensure constant tension during operation.
  • Good heat dissipation: Thanks to the radiator built into the friction disc, the FNH brake offers excellent heat dissipation capacity. This is essential to maintain constant performance during continuous use without the risk of overheating.
  • Reduced weight: The lightweight construction of the FNH pneumatic brake makes it easy to handle and install. Its reduced weight contributes to greater versatility and ease of use in a variety of industrial applications.
  • Torque proportional to pressure: The direct relationship between the air pressure applied and the braking torque generated allows precise linear control over the unwind tension, which is essential in applications where tight control is required.
  • Minimal inertia: The low inertia of the FNH brake means it can respond quickly to changes in air pressure, resulting in greater controllability and real-time adaptability.
  • Axles in different position: The ability to use the brake on differently positioned axes is a valuable feature that extends its versatility and applicability in a variety of industrial configurations.
