Integrated Filter Media Solutions for Industrial Filtration Systems
Release time:
2025-12-18
In the field of industrial solid–liquid separation, different filtration equipment impose highly differentiated requirements on filter media in terms of structure, permeability, mechanical strength, retention accuracy, and fabrication details.
Xiamen Citius Filter Media Technology Co., Ltd. has long maintained close technical collaboration with filtration equipment manufacturers worldwide. By focusing on three core elements—equipment structure, process conditions, and filtration objectives—Citius has developed a systematic filter media solution portfolio covering a wide range of filtration equipment.
This article provides a structured overview of Citius’ major filter media product systems, organized by equipment type.
I. Filter Belts for Coolant Filtration
Serving precision machining and metal cutting applications
In coolant filtration for machining processes, the key challenge lies in balancing high-efficiency retention of fine particles with stable operation at high flow rates. Through joint development with equipment manufacturers, Citius offers precision-engineered filter belts tailored to different machine designs, including:
- Vacuum belts
- Press belts
- Screen filter belts
Representative Products and Technical Features
- Composite filter fabrics
Designed for fine separation of particles below 80 μm, combining minimal pore size with a large open area. - Double-layer filter fabrics
Featuring a fine filtration layer supported by a high-strength backing layer, providing a smooth filtration surface for stable performance and efficient cake release. - Seam and joint solutions
Specifically developed for coolant filter belts, ensuring zero leakage of fine particles, flat seam geometry, and reliable sealing in the joint area. - Polymer-coated edges
Edge widths up to 120 mm, enhancing running stability and edge durability.
II. Press Belts for Belt Presses
Covering sludge dewatering and food pressing processes
Citius press belts are widely used in:
- Organic and inorganic sludge dewatering
- Juice extraction and plant-based liquid pressing
Structural Advantages
- Multiple weave patterns and permeability options to match different press designs
- Maximum belt width up to 3.5 meters
- Optional coated or uncoated edges
- Heavy-duty metal clipper seams for high-tension operation
- Twill weaves for enhanced overall strength
- Satin weaves balancing cake release and permeability
III. Filter Cloths for Filter Presses
Standardized products combined with in-depth customization
In addition to standard filter press cloths, Citius provides highly customized solutions based on specific operating conditions, covering:
- Hanging filter cloths
- Recessed chamber cloths
- Plate-and-frame filter cloths
- Special-structure filter press fabrics
Key Fabrication and Design Features
- Standard neck designs and EPDM neck structures
- Latex-sealed edges for drip-free operation
- Multiple fixing options such as glued hems and eyelets
- Easy installation and removal for high-frequency replacement scenarios
IV. Filter Bags for Leaf Filters
Designed for cleanability and long-term operational stability
Citius leaf filter bags are characterized by monofilament and multifilament constructions, ideal for processes requiring frequent cleaning and regeneration.

- Integrated double-layer structures enhancing drainage efficiency and mechanical stability
VIII. Filter Belts for Vacuum Belt Filters and Rotary Drum Filters
Vacuum Belt Filters
- Filtration range: 7–150 μm
- Belt widths up to 3.5 meters
- Polyurethane-coated edges for sealing and protection
- Double-layer fabrics with permeability ranging from 30 to 2400 L/m²·s
- Support for on-site welding installation
Rotary Drum Filters
- Filtration range: 2.5–150 μm
- Multiple material options available
- Optional rubber guide belts and metal clipper seams
- New-generation fabrics designed for fine particle filtration
IX. Products for Bag Filters and Candle Filters
- Loop-top, steel-ring, and flange-type filter bags
- Woven, welded, and stitched candle filter elements
- Smooth surfaces with customized dimensions
- Coverage from micron-scale woven meshes to high-efficiency filter media
X. Conclusion: More Than Filter Media—A Part of the Filtration System
From coolant filtration to mineral dewatering, from pharmaceutical fine filtration to advanced material separation, Xiamen Citius consistently designs its products around equipment compatibility, process adaptability, and long-term operational stability.
Filter media are not merely consumables—they are critical components that directly influence the efficiency, energy consumption, and total operating cost of the entire filtration system.
The true value of Citius lies in this philosophy:
Transforming filter media into an integral part of the filtration system itself.
