About 400 Micron Filtration
What Is a 400 Micron Filter Bag?
A 400 micron filter bag is a coarse filtration element designed to remove larger suspended particles, process debris and solid contaminants from industrial liquids. Compared with 50 or 150 micron grades, it can support higher flow and lower resistance in many applications.
400 µm filter bags are commonly used as pre-filters before finer filtration, as primary filters in higher-solids applications or as screening filters for larger particles. Media selection should consider fluid chemistry, temperature, viscosity, particle shape, solids loading and reuse requirements.
Coarse Particle Removal
Captures larger contaminants before they reach finer filtration stages or process equipment.
High Flow Potential
Supports lower resistance and higher throughput in many industrial processes.
Screening & Pre-Filtration
Suitable for upstream protection, solids classification and general process cleanup.
Wide Material Choice
Available in verified nylon, polypropylene, polyester and PEEK monofilament constructions.
400 µm Filtration Performance
A Verified Monofilament Grade for High-Flow Coarse Screening
400 micron filter bags are widely selected when customers need larger solids removal, reduced pressure drop and protection for downstream equipment or finer filters. Ince supplies standard and custom designs for industrial bag filter housings and OEM systems.

Frequently Asked Questions
400 Micron Filter Bag FAQ
What does 400 micron mean in a filter bag?
A 400 micron filter bag is designed for coarse industrial liquid filtration and solids screening. It is used to remove larger suspended particles while maintaining high process flow.
When should I choose 400 micron instead of 300 micron?
Choose 400 micron when higher flow, lower resistance or larger solids handling is more important than the finer particle retention of a 150 micron filter bag.
When should I choose 400 micron instead of 600 micron?
Choose 400 micron when the process requires slightly finer particle control. Choose 400 micron when very large debris removal, heavy solids or maximum throughput is the priority.
Which materials are actually available for 400 micron filter bags?
Yes. 400 micron nylon filter bags are well suited to surface filtration, particle screening and reusable filtration where nylon media is compatible.
Which 400 micron filter bag sizes are available?
Common options include Size #01, #02, #03 and #04. Ince also manufactures custom diameters and lengths for special filtration systems.
