As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory brings decades of precision engineering to the Industrial Water Treatment Water Purifier Filter Element, 40-Inch Big Blue, 5 Micron Pleated. This filter element is designed to provide reliable, high-performance sediment filtration for demanding industrial applications. Crafted with advanced pleated technology, it offers a large surface area for extended service life and consistent water quality. Whether you are protecting downstream equipment or ensuring clean process water, this cartridge delivers the efficiency and durability your system requires.
Our 40-inch Big Blue filter is a direct replacement for standard housings and is built to handle high flow rates while maintaining a low pressure drop.

- Universal Fit: Compatible with standard 40-inch Big Blue filter housings (4.5-inch outer diameter). End cap styles available: double open end, flat cap, or custom.
- Material Options: Standard polypropylene (PP) for general use; also available in polyester (PET) or nylon for chemical compatibility (customizable upon request).
- High Flow Performance: Supports flow rates up to 40 GPM (151 L/min) depending on housing and water quality, with minimal pressure loss.
- Temperature & Pressure Ratings: Operates effectively from 40°F to 125°F (4°C to 52°C) and withstands up to 125 psi (8.6 bar) without deformation.
- Easy Installation: Lightweight and rigid structure ensures quick change-out without special tools.

Frequently Asked Questions (FAQ)
- Can this filter be used for drinking water? Yes, this filter is suitable for potable water systems when used with approved materials. The standard polypropylene media is FDA-compliant for food contact (available upon request).
- What is the recommended replacement interval? It depends on influent water quality and flow rate. Typically, for sediment-laden water, replace every 3-6 months. Pleated filters may last longer than depth filters due to higher dirt holding capacity.
- Is this filter compatible with all Big Blue housings? This 40-inch cartridge fits standard Big Blue housings with a 4.5-inch outer diameter. Ensure your housing has a 40-inch sump height. Double-check your housing model for compatibility.
- Can I wash and reuse the pleated filter? Some pleated filters are washable (e.g., polyester media). However, our standard polypropylene version is designed for single-use replacement. Reusable options are available as custom orders.
- What is the maximum flow rate through this filter? The maximum recommended flow rate is 40 GPM at 125 psi. Exceeding this may cause pressure drop and reduce filtration efficiency. Check your system design.
- Does the filter remove chlorine or chemicals? No, this is a sediment filter (5 micron). It does not remove dissolved contaminants like chlorine, taste, or odor. For chemical reduction, use a carbon filter in series.
- What end cap options are available? Standard is double open end (DOE). We also offer flat cap, O-ring, or custom configurations. Please specify your requirement when ordering.
- How is the filter packaged for export? Each cartridge is individually shrink-wrapped, then packed in export cartons. Custom packaging (private label, bulk) is available.
