High Flow Filter Cartridge RTM41HF050E

The RTM41HF050E High Flow Filter Cartridge is a premium-quality, high-capacity filtration solution engineered to deliver exceptional flow rates, long service life, and reliable particulate removal for large-scale water and liquid treatment systems. Designed as a direct, high-performance replacement for original filters, this 40-inch cartridge features a large 6.5-inch outer diameter, a 5-micron filtration rating, and a unique outside-in flow path.

The RTM41HF050E combines both surface and depth filtration mechanisms, utilizing a high-porosity, pleated polypropylene media. This advanced structure allows a single cartridge to achieve flow rates up to 1,300 liters per minute -equivalent to replacing up to ten standard 40-inch cartridges. By drastically reducing the number of elements required and the overall filter housing footprint, this high flow cartridge delivers significant capital and operational savings while maintaining superior filtration efficiency and minimal pressure drop.

• Reverse Osmosis (RO) Pre-Filtration & Pretreatment: Installed in "security" filter housings upstream of RO membranes to remove suspended solids, silt, and particulates, preventing membrane fouling and extending membrane service life.
• Seawater Desalination Pretreatment: Critical for removing marine particulates and colloidal matter prior to desalination processes.
• Industrial Process Water & Cooling Water: Treating make-up water, cooling tower feed, and industrial process loops in power generation, steel mills, and chemical plants.
• Power Generation (Condensate Polishing): Used in condensate filtration systems to remove corrosion products and particulates.
• Pharmaceutical & Biotech: Filtration of raw materials, solvents, process water, and intermediate solutions in API production and bioprocessing.

Huahang Filter is dedicated to engineering replacement parts that meet or exceed original specifications for fit, form, and function. With a modern 26,000㎡ ISO-certified facility, we ensure every cartridge delivers consistent performance, chemical compatibility, and long service life-trusted by clients in over 120 countries, with exports representing over 80% of our business.

Core Manufacturing Strengths

• Precision Engineering for Exact Fit: Every critical dimension is precisely replicated, guaranteeing a perfect, bypass-free seal in standard Parker/RTM series housings.
• Advanced Media & Construction Technology: Our high flow cartridges utilize deep-pleated PP media optimized for surface and depth filtration. The thermally bonded, all-polypropylene construction eliminates adhesives, prevents media shedding, and ensures low extractables, meeting high-purity application standards.
• Material Versatility: We manufacture high flow cartridges in a full range of media and filtration ratings. For standard water applications, PP media is ideal.

Q: What is the flow direction for this cartridge?
A: The RTM41HF050E operates with an outside-in flow path. Fluid enters through the outer surface, passes through the pleated media, and exits through the open inner core. This design ensures contaminants are captured on the exterior of the filter for easy inspection.

Q: How many standard cartridges does one RTM41HF050E replace?
A: A single 40-inch RTM41HF050E high flow cartridge can replace approximately 10 standard 40″ × 2.5″ cartridges, significantly reducing housing size, installation labor, and change-out frequency.

Q: What is the recommended replacement pressure drop?
A: For optimal performance and to avoid bypass, replace the filter when the pressure differential reaches 3.4 bar at 82°C (or approximately 2.4 bar at 20°C for water applications).

Q: Is the filter compatible with oils and solvents?
A: Yes, the standard polypropylene (PP) construction offers excellent compatibility with a wide range of mineral-based oils, coolants, and mild solvents. For aggressive chemical applications or higher temperature requirements, glass fiber media or specialty sealing materials (e.g., Viton, Teflon-coated) are available.

Q: Can this filter be cleaned and reused?
A: This filter is designed as a disposable cartridge. To restore performance, it should be replaced when the recommended pressure drop limit is reached. For applications requiring a cleanable, permanent solution, please refer to our sintered stainless steel filter elements.
