FYN-M1

Vane dampers

FYN-M1 Series
Bansbach vane dampers and dashpots are used to dampen drives, control speed, and many other applications. Our rotational viscous dampers are maintenance free and the most durable units on the market. Bansbach silicone oil viscous dampers are available in either fixed rate or adjustable models. On adjustable vane dampers adjustment is made with an integrated set screw.
The damping direction of the vane dampers with continuous rotation can be clockwise, counter clockwise, or in both directions. In vane dampers with continuous rotation, a fluid damping is produced by the shearing or braking force of silicon fluids resistance between the surfaces of a rotor and a stator. The damping moment is determined by the viscosity of the fluid and the size of the orifice or gap. The damping characteristics can be customized by changing the viscosity of the silicon fluid or by changing the structure of the rotor and stator. vane dampers life-cycles are typically in excess of 50,000 cycles. The service life may be significantly higher or lower, depending on the application. After extended life cycles the dampers still produce over approx. 80% of their original damping moment.

Characteristics
The time it takes for a lid with a damper to close varies according to the ambient temperature. As the temperature increases, it takes less time, and as the temperature decreases, it will take longer for the lid to close. This is because the viscosity of the oil inside the damper changes according to the temperature. When the temperature returns to normal, the required time will return to normal as well. The temperature characteristics are shown in the graph below. FYN-D3 damping characteristics
The FYN-M1 series is a fixed type; its torque is nonadjustable. However, a customized order for a torque of 0.15 ~ 0.6Nm is possible by changing the oil viscosity

FYN-N1 diagram
The FYN-M1 Series is designed to generate a large torque up to 90° in a closing lid, as shown in Diagram A, and the lid is able to close completely. However, when the lid is closed from a vertical position, as shown in Diagram B, the lid cannot be slowed down, as the torque decreases just before the lid is completely closed.
This diagram shows the relationship between the load torque and the time when a lid is closed from a 160° angle.
