Independent research, development, and production

Independent R&D, independent production, independent sales. The three independent core patents ensure the excellent quality of ceramic filter tubes: ceramic fiber ultra-fine shear technology, internal model integrated molding technology, and nano-catalyst impregnation technology.

Ultra-low resistance
ultra-high strength

By achieving precise chemical ratios of fiber materials, highly consistent fiber diameters and lengths, over 50 cycles of catalyst impregnation, we produce high-strength, low-resistance ceramic filter with ultra-long service life and ultra-low energy consumption.

Long-lasting
low-cost

Compared to the lifespan of other three-year products, it offers a five-year warranty, allowing free replacement within five years without human damage. Under specific conditions, its lifespan may reach 8 to 10 years. A longer service life reduces usage and maintenance costs.

Verification technology
widely used

Over 50 gas treatment projects have been independently designed, constructed, and operated using ceramic integration technology, and have been promoted nationwide as a typical case of flue gas treatment twice. They are exported to East Asia, Southeast Asia, and Europe.
