Replacement for 3M™ 740B High Flow Filter Cartridges | 1:1 HFM Series Technical Cross-Reference
High-Performance "Bag-to-Cartridge" Upgrade for #2 Bag Housings
Looking for a reliable alternative to 3M™ 740B filters? Our HFM series is a 100% technical match, designed to fit perfectly into standard Size #2 Bag Filter Housings. This solution allows you to upgrade from traditional filter bags to high-efficiency pleated technology without any hardware modifications.
By utilizing an Inside-to-Outside flow direction, the Ecofiltrone HFM series ensures all captured contaminants are trapped within the cartridge, preventing downstream pollution during filter change-outs.

Industrial Applications & Solving Your Filtration Challenges
1. High-Precision Retrofitting for Bag Systems
- The Challenge: Standard liquid bags often suffer from low efficiency and “fiber migration,” leading to inconsistent water quality in critical processes.
- Our Solution: The HFM series provides a rigid, pleated structure that offers significantly higher surface area than a standard filter bag.
- Performance Advantage: Achieves up to 10 times the service life of traditional bags, minimizing downtime and labor costs while maintaining high-efficiency retention.
2. Petrochemical and Hydrocarbon Processing
- The Challenge: Fluids with high solids content can cause traditional bags to burst or bypass under pressure surges.
- Our Solution: Built with high-strength polypropylene components, our HFM series maintains structural integrity up to 3.44 bar.
- Performance Advantage: The specialized sealing flange ensures a bypass-free fit in standard baskets, protecting downstream equipment from abrasive particulates.
3. Protection of RO Membranes in Water Reuse
- The Challenge: Fine colloids and silt in wastewater can quickly foul expensive RO membranes if pre-filtration is inadequate.
- Our Solution: Gradient density polypropylene media provides multi-layer depth filtration, capturing a wide range of particle sizes.
- Performance Advantage: Stabilizes Silt Density Index (SDI) values, extending membrane life and reducing the overall energy consumption of the RO system.

FAQ
Q1: Will the HFM series fit my competitive bag housing (e.g., Eaton, Pentair)?
A1: Yes. The HFM is designed to fit standard #2 bag baskets, which are the industry standard across multiple brands.
Q2: How does the “Inside-to-Outside” flow direction benefit me?
A2: It keeps all filtered solids contained within the core of the filter, so they don’t fall back into the clean side of the housing during removal.
Q3: Can you provide customized micron ratings for the HFM series?
A3: Yes, while 1-100 $\mu m$ is standard, we can customize the media density for specific high-viscosity or sensitive fluids.
