Used filters are essential components in countless process operations where solids must be separated from liquids. Whether you’re removing fine particulates, clarifying solutions, or recovering valuable materials, industrial filters play a critical role in improving product quality, protecting downstream equipment, and maintaining compliance. With more than 47 years of experience, IPP supplies used, secondhand, and surplus filters from 20 global plant sites and maintains an extensive inventory of 15,000+ process systems.

IPP stocks a wide range of filter types—pressure leaf, plate and frame, cartridge, vacuum drum, nutsche, and candle filters—from leading brands like Sparkler, Pall, Funda, and Millipore.

Primary uses across industries

In chemical processing, for separating solids from liquids in catalyst recovery, resin filtration, and acid clarification
In pharmaceuticals, for sterile filtration of intermediates, APIs, and final formulations
In food and beverage, for wine clarification, edible oil filtration, and sugar refining
In environmental and wastewater, for sludge dewatering and contaminant removal

Types of materials processed

Slurries, suspensions, and solutions with fine particulates
Heat-sensitive or viscous liquids requiring gentle handling
Solvent-based, aqueous, or corrosive mixtures

Common materials of construction

Industrial filters are built to resist corrosion, handle pressure, and maintain hygiene:

Stainless steel for sanitary, pharma and food-grade use
Carbon steel for robust chemical and utility processes
Hastelloy, titanium or lined steel for aggressive media or high-purity applications

Key features of process filters

Multiple filter formats to match flow rate and solids content
Jacketed options for temperature-sensitive operations
ASME code-rated vessels available for pressure applications
Options for automated cake discharge or backflushing
Compact, modular systems designed for integration and easy maintenance
