RTM61HF200E 60 Inch High Flow Filter Cartridge
Introduction:If you are sourcing RTM61HF200E 60 inch high flow filter cartridge for high turbidity raw water pretreatment and large-volume industrial water filtration, this coreless gradient polypropylene pleated filter provides stable 20 micron coarse filtration performance. Featuring an ultra-long 60-inch body and maximum filtration area, it delivers ultra-high dirt holding capacity and low pressure drop operation. It effectively intercepts coarse sediment, rust scale, large suspended solids and macroscopic impurities in raw water, greatly reducing the load on downstream fine filters and RO membrane systems. As a high-efficiency and cost-saving replacement filter element, it is widely used in large seawater desalination plants, power plant water systems, petrochemical plants and municipal large-scale water pretreatment projects.

Product Overview
RTM61HF200E is a 60-inch ultra-large flow security filter cartridge in the LEFILTER RTM series. Compared with conventional 40-inch filter elements, the 60-inch extended structure provides significantly larger filtration area and higher pollutant carrying capacity, making it ideal for high-flow and high-turbidity water treatment systems. The cartridge adopts 6-inch large outer diameter, single open-end structure and inside-to-outside radial filtration mode. The filter media is high-strength gradient polypropylene with open pleat design, which is not easy to block and maintains stable flow under harsh raw water conditions. All connections adopt hot-melt welding process without glue, eliminating secondary water pollution. Reinforced polypropylene end cap and integrated lifting handle ensure structural firmness and fast tool-free replacement. Standard EPDM seal is equipped, with silicone, FKM and Buna-N optional for corrosive and high-temperature working environments. It is the best choice for primary coarse filtration of large-scale industrial water systems.
Working Principle
RTM61HF200E high flow filter cartridge applies standard inside-to-outside depth filtration principle. High-turbidity raw water enters the inner cavity from the top open end and flows radially outward through multi-layer gradient PP pleated media. Large particles such as gravel, thick sediment and rust flakes are intercepted on the inner coarse pleat layers, while tiny fine particles are further filtered through outer dense layers. The ultra-long pleat structure optimizes water flow distribution, avoids local congestion and clogging, and effectively delays differential pressure increase. The high-tightness sealing structure prevents unfiltered liquid bypass to ensure stable 20μm coarse filtration effect. All contaminants are locked inside the cartridge, ensuring safe, fast and clean replacement.
