Silicone coated dust bag cages are enhanced versions of standard filter bag cages, designed specifically for use in harsh industrial environments. By applying a special silicone coating on the surface of carbon steel or galvanized cages, the product achieves exceptional performance in terms of corrosion resistance, heat resistance, and abrasion resistance.
This innovative coating enables the cages to withstand aggressive flue gases and high-temperature conditions, making them particularly suitable for desulfurization systems and dust removal equipment in power plants. In many cases, silicone coated cages can even serve as a cost-effective alternative to stainless steel filter bag cages.
Silicone coated cages are engineered for use in demanding filtration environments where traditional cages fail due to corrosion or thermal degradation. They are especially beneficial in:
These cages are generally matched with PTFE, P84, or fiberglass filter bags to withstand aggressive operating conditions.
| Feature | Benefit |
