The intelligent damper: easyERF Electronic adjustable dampers according to the electrorheological technology
The Bansbach® easyERF dampers are extremely quick and efficient dampers with a broad application field. Its innovation potential is the electronically adjustable damping intensity and the reaction time within milliseconds. Advantages of the damper: no wear and tear, maintenance-free, high reliability.
Continuously variable
a complete characteristic damper field is available Digital control
by adapting the electrical input signal, the damping can be adjusted; either with PWM-standard or with 0 - 4 V analog signal.
SPS is possible; supply 24 V DC
Response characteristics
the required damper force can be realised with a reaction time of only few milliseconds
Noiceless and maintenance-free
no "laminar flow noices", no "whistling noices", no moveable valve parts energy-efficient
low consumption; high efficiency

Fact sheet (PDF 1,5MB)  | The technology:In the electrical field, the electrorheological fluid changes its consistency from thick to thin within milliseconds. According to the ERF-technology, the dampers adapt very quickly to changing system requirements, using as little energy as possible.
An electrical signal determines the damper forces which can thus be optimally adapted to operating excitation forces.
The damping force can consequently be adjusted within the characteristic field - quick, at any time, noiceless - and only by the use of a simple electronic interface. Movie (2MB) |
