OPERATING CONDITIONS
- The silencer is designed to reduce the noise level of compressed air exhaust. Other noises produced by equipment vibration, valve switching, etc. are not muffled.
- The inlet pressure when measuring flow capacity refers to the pressure immediately in front of the silencer.
- If the compressed air is contaminated with oils or droplet moisture, there may be a decrease in the silencer’s flow capacity and spraying into the environment. It is recommended to use moisture-oil separators when preparing the air.
- The silencing characteristics may depend on the design and arrangement of pneumatic system components and may differ from those specified here.
- The silencer consists of two parts: a porous silencing cap and a solid metal fitting.
- Installation. Use a wrench for tightening. Only tighten and loosen by the hexagon element. The permissible tightening force limits are indicated in the table below.
| Model | Tightening force, N×m |
| GR-SW G1-8 | 10…12 |
| GR-SW G1-4 | 12…14 |
| GR-SW G3-8 | 22…24 |
| GR-SW G1-2 | 28…30 |
| GR-SW G3-4 | 28…30 |
| GR-SW G1 | 36…38 |
- Operation. Use the products strictly under the specified temperature and pressure conditions. Do not apply lateral bending loads during installation and use. If the product is used under vibration conditions, the threaded connection may become loose. It is allowed to use thread locking compounds.
- Maintenance. It is recommended to regenerate the silencer every quarter by using reverse purging with compressed air, followed by washing in a solvent. If regeneration does not restore the required flow capacity, replace the silencer.
- Disposal. The product material is renewable and can be recycled as aluminium scrap. The porous silencing part is made of casting alloy AC-42000.
