A Silicone Bag Cage is a high-performance filter support cage where the steel wire frame is coated with a high-temperature silicone rubber coating. This specialized coating provides superior protection against corrosion, adhesion, and abrasion, making it the ideal choice for highly corrosive environments, sticky dust applications, and high-temperature processes where standard galvanized or epoxy-coated cages would fail.
A Silicone Bag Cage is a type of bag cage that is specially coated filter support cage designed for use in industrial dust collection systems.
It is basically Constructed from high-strength steel and coated with silicone resin and it offers superior resistance to heat, corrosion and chemical attack thats extending the service life of both the cage and the attached filter bag.
Our Silicone bag cages are ideal for high-temperature and chemically aggressive environments where traditional galvanized or epoxy-coated cages cannot perform effectively.
