Pneumatic spring brakes FNAM and FNA are units for work on horizontal axes, with a high degree of reliability, good heat dissipation, fast response speed and minimal residual torque.
The two brakes have practically the same characteristics, unlike the FNAM being a negative air brake and the FNA being a positive air brake.
Below is a detail of how the FNA and FNAM Air Brakes work
FNAM. Negative air brake
• Without air pressure the brake stays active and does not allow the application to move.
• When pressurized air (max. 6 bar) is applied, the brake is released and allows the application to move.
The braking torque is from 8.5 Nm.
FNA: Positive air brake.
• Without air pressure, the brake springs release the disc and allows the application to move.
• When pressurized air (max. 6 bar) is applied, it remains braked and does not allow the application to move.
The braking torque is from 12 Nm.
Pneumatic spring brakes FNAM and FNA can be used for different types of machinery, such as:
Cleaning of buildings and facades
