Types of Used Filters Available
Aaron Equipment offers a variety of used filters designed for different separation processes, throughput requirements, and material characteristics.
Filter Presses – Batch filtration systems that use pressure to separate solids from liquids, commonly used for sludge dewatering and high-solids applications.
Nutsche Filters – Enclosed filtration units ideal for solid-liquid separation, washing, and drying in pharmaceutical and chemical processing.
Rotary Vacuum Filters – Continuous filtration systems used for high-volume separation of slurries in chemical, mineral, and wastewater operations.
Pressure Leaf Filters – Vertical or horizontal vessels designed for high-efficiency filtration of liquids with low solids content.
Cartridge Filters – Compact filtration systems used for fine particle removal and polishing applications in food, beverage, and pharmaceutical processes.
Horizontal Belt Vacuum Filters – Continuous filtration systems designed for large-scale solid-liquid separation and cake washing applications.
Filter Applications & Industry Uses
Used filters are essential in processes requiring separation of solids from liquids or gases to improve product quality and process efficiency. Depending on the filter type, these systems support batch or continuous filtration, fine particle removal, and dewatering.
Common industries and applications include:
Chemical processing: Catalyst recovery, slurry separation, and product purification
Food and beverage: Clarification, polishing, and ingredient processing
Pharmaceutical and biotechnology: Sterile filtration and product recovery
Wastewater treatment: Sludge dewatering and solids removal
Mining and minerals: Tailings processing and slurry filtration
Used Filter Buying Considerations
When selecting a used filter, evaluate both process requirements and equipment condition:
Filtration Type and Process Design: Determine whether batch or continuous filtration is required
Throughput and Capacity: Match system size and filtration area to production needs
Material Compatibility: Ensure construction materials suit process fluids and operating conditions
Automation and Controls: Review control systems, discharge mechanisms, and integration requirements
Condition and Maintenance History: Inspect filter media systems, plates, seals, and structural components
Why Buy Used Filters
Buying used filters can significantly reduce capital costs while still delivering reliable separation performance. Many filtration systems are available for immediate shipment, helping facilities avoid long OEM lead times. Purchasing used equipment also provides access to proven filtration technologies already used in demanding industrial environments.

A filter is an industrial separation device used to remove solids from liquids or gases. Filters are commonly used in processes requiring clarification, purification, or dewatering across many industries.
Used filters include filter presses, nutsche filters, rotary vacuum filters, pressure leaf filters, cartridge filters, and horizontal belt vacuum filters. Each type is designed for specific filtration processes, material characteristics, and production requirements.
Choosing the right filter depends on the type of material being processed, solids concentration, required throughput, and whether batch or continuous operation is needed. Equipment design, filtration media, and construction materials should also align with process requirements.
The cost of a used filter varies based on type, size, manufacturer, capacity, and condition. Larger or specialized filtration systems typically command higher prices. Availability and application requirements will also influence pricing.
