Pressure drum filter for fine-grained products
Achieve exceptional precision in fine particles processing with this pressure drum filter, designed for seamless integration in high-demand operations where low residual moisture and high throughput are critical. Perfect for those tackling challenging filtration, washing, and dewatering needs in continuous production environments.
Performs Continuous Filtration, Washing, and Dewatering
The BoHiBar Drum Filter from BOKELA is designed for continuous pressure filtration, washing, and dewatering of challenging fine-grained products. Its unique closed system utilizes high differential pressures up to 6 bar (g) for efficient filtration and minimal residual moisture, making it suitable for chemicals, pharmaceuticals, and pigments production. This equipment uses hyperbaric filtration principles, integrating seamlessly into production lines with fully automatic operations and PLC controls. Its compact design offers substantial space savings, while steam pressure filtration further reduces drying requirements, cutting energy costs significantly. Constructed with durable materials like stainless steel, it ensures chemical compatibility and longevity under harsh conditions. BoHiBar complies with industry standards and features a CIP system for effective cleaning, maintaining operational integrity. Custom engineering support is available, ensuring precise adaptation to specific production needs.
