VIBROFLEX suspension type 4
VIBROFLEX suspension type 4
Vibration-isolating hangers VIBROFLEX type 4 are used during the installation of power units and communications of various engineering equipment to reduce the transmission of vibrations to the building’s enclosing structures.
VIBROFLEX Type 4 hangers are used for vibration isolation of pipelines and power units of various engineering equipment (ventilation, water supply, heating and air conditioning, and sewerage systems). Sylodyn, a special vibration-insulating material, is used as the elastic element of the hanger. Each hanger type is designed for a specific load capacity. M8 threaded studs are used for equipment suspension.
Depending on the load size, 5 types of hangers are produced:
| Name | Color of the elastic element | Maximum load on suspension, kg | Minimum resonant frequency, Hz |
|---|---|---|---|
| Vibroflex 4/7 M8 | pink | 7 | 11.4 |
| Vibroflex 4/15 M8 | yellow | 15 | 10.6 |
| Vibroflex 4/30 M8 | green | 30 | 10.7 |
| Vibroflex 4/55 M8 | blue | 55 | 11.1 |
| Vibroflex 4/70 M8 | violet | 70 | 11.6 |
Distinctive features
- VIBROFLEX suspensions are effective in both low and medium and high frequency ranges;
- Anodized metal suspension elements;
- Stability of vibroacoustic properties over a long period of time (at least 50 years).
