Low frequency dampers for building isolation, this dampers isolate vibrations coming from railways paths, earthquakes (depending project), dynamic loads from general machinery, > 300 rpm, big fans, nuclear applications, pumps, compressors, etc, etc.
- All metallic plates in carbón Steel, with surface treatment for all environmental conditions.
- Spring with Steel in high resistance and mechanical infinite life, high resistance surface treat-ment.
- Damping coming from the inside metallic cushion in stainless steel.
- Axial natural frequency: 3 - 5 Hz.
- Maximum dynamic charge: 4 g vertical, 0,5 g horizontal. Under requirement 10 g´s.
