BROLERN sintered bronze cartridges use RoHS-compliant material. Moulds are complete and the process is stable and repeatable, keeping micro-pore distribution uniform. The media resists acid and alkali corrosion and reaches filtration ratings down to 0.5 µm, mainly for filtration and silencing of air, water and oil.
The family is widely used in pneumatics, chemical processing, food, pharmaceutical and environmental industries. Custom shapes are manufactured to customer drawings or samples.
