Product Introduction
HF640-60 high flow filter cartridge is a horizontal installed large flow pleated filter, specially developed for the pre-filtration stage of industrial RO water treatment systems. This high flow filter cartridge is perfectly matched with the corresponding water filter housing, and can work together with a self-cleaning filter to build a multi-stage protection system for raw water. Compared with conventional small-size filter cartridges, it boasts remarkable single-element flow rate, which greatly decreases the quantity of cartridges needed in the filter vessel. Original Pall high flow filters have well-known pain points: high unit price, long lead time for overseas orders, and once the filter media suffers uneven pleat compression, the effective filtration area will drop rapidly. Our HF640-60 adopts reinforced polypropylene pleated media, optimizes the pleat structure to avoid collapse under high differential pressure. It maintains stable particle holding capacity, and can perfectly serve as a drop-in replacement for Pall HF series high flow elements without modifying existing filter housings. Available in multiple micron ratings to match different raw water quality, this filter offers stable protection for RO membranes in industrial, municipal and commercial water purification projects.
Working Principle
The raw water enters from the outer layer of the filter cartridge and flows inward through the multi-layer pleated filter media. Suspended particles, silt, rust and colloidal impurities are trapped on the surface and depth of the polypropylene medium. Clean water flows through the inner core and exits to the downstream RO system. The deep pleated structure expands the effective filtration area. As contaminants accumulate, the filter gradually builds up differential pressure. Once the pressure difference reaches the preset threshold, operators can replace the cartridge in minutes. This pre-filtration step removes most large particles in advance, preventing particulate pollutants from scratching and fouling expensive RO membranes, extending the service life of RO elements significantly.

Core Advantages
1. High Single-element Flow:
One HF640-60 cartridge achieves the flow output of dozens of standard 20" filter cartridges, which reduces the number of filter elements inside the housing and lowers inventory management workload.
2. Cost-effective Replacement for Pall HF Series:
Original Pall high flow cartridges carry high procurement cost and long delivery cycles. Our HF640-60 matches the installation dimension and filtration performance, with shorter lead time and lower total cost of ownership. The reinforced pleat design solves the common defect of Pall products — pleat deformation under high pressure that shortens filter service life.
3. Excellent Fouling Holding Capacity:
Wide pleat spacing and large filtration area capture massive suspended solids before they reach RO membranes, reducing RO membrane cleaning frequency.
4. Wide Chemical Compatibility:
All polypropylene construction resists most acids, alkalis and aqueous solutions, suitable for diverse raw water conditions.
5. Easy Installation & Maintenance:
DOE connection design supports quick cartridge replacement. Less cartridge quantity means shorter shutdown time during maintenance.
Application Scenarios
RO system pretreatment for industrial pure water production
Municipal water supply filtration
Cooling tower side stream filtration
Food & beverage process water treatment
Seawater desalination pre-filtration
Power plant boiler feed water filtration
FAQ
Q1: Can HF640-60 directly replace Pall HF640 series high flow filter cartridges?
A1: Yes. It adopts the same size and DOE interface, no need to modify your existing filter housing. It can be directly replaced.
Q2: What micron rating should I select for RO pretreatment?
A2: For standard RO pretreatment, 5μm or 10μm are the most common choices. If raw water contains heavy silt, you can choose 20μm as primary filtration.
Q3: What is the typical service life of HF640-60?
A3: Service life depends on raw water turbidity. Under normal raw water conditions, it can work for several weeks; heavy pollutant load will shorten its service cycle. Monitor differential pressure to judge replacement timing.
Q4: Is this filter element cleanable and reusable?
A4: The polypropylene pleated high flow filter is disposable. Once the pressure difference reaches the limit, replacement is recommended. Repeated cleaning will damage filter media and reduce filtration accuracy.
Q5: What is the maximum working pressure for HF640-60?
A5: The maximum allowable differential pressure is 3.4 bar at 20℃. Operating beyond this value may cause pleat damage.
