I. Basic Structure and Dimensions
Main lengths: 40 inches (1016mm), 60 inches (1524mm)
Interface types: 226/222 snap‑in type, flange type, threaded interface
Flow direction: outward‑in, large‑diameter large flux filter element, high open‑hole rate frame, water flow volume far exceeds that of ordinary folded filter element
Common precisions: 1μm, 5μm, 10μm, 20μm, 50μm, 100μm
II. Flow Performance (Clearwater at 25°C, Rated Flow)
Single standard flow
40‑inch high flow pleated filter element: 40‑60 m³/h
60‑inch large flow filter element: 60‑90 m³/h
Pressure drop - Flow characteristic
Initial pressure drop (clearwater, 5μm): ≤ 0.02 MPa
Normal working pressure drop: 0.1 - 0.3 MPa, stable flow, small attenuation
Suggested replacement pressure drop: 0.35 - 0.4 MPa
Advantage: Low pressure loss, high flow rate, filter element quantity is reduced by more than 70% compared to ordinary filter elements under the same filtration capacity
III. Filtration Capacity (Filtration Dust Capacity, Determines Service Life)
40‑inch high flux filter element (5μm, PP material)
Filtration capacity: 12 - 16 kg / piece
60‑inch high flow water filter element (5μm, PP material)
Filtration capacity: 18 - 24 kg / piece
The filtration capacity is 3 - 5 times that of ordinary folded filter elements, suitable for high suspended matter and high impurity conditions.
Service life reference
Pure water / tap water pre‑filter: 4 - 8 months
Surface water, circulating water, reclaimed water: 1 - 3 months
Seawater desalination, power plant pre‑treatment: 2 - 4 months
IV. Filtering Performance
Filtering efficiency
1μm: ≥ 99.95%
5μm: ≥ 99.9%
Absolute fine filtration, no bypass leakage, meets the requirements of RO reverse osmosis, seawater desalination, industrial precise pre‑treatment.
Filter membrane material
Standard: PP polypropylene (resistant to water, resistant to common chemicals, highest cost performance)
Optional: Nylon nylon, PTFE polytetrafluoroethylene (resistant to acids and alkalis, resistant to solvents, resistant to high temperatures)
Supporting frame: reinforced polypropylene, resistant to pressure, anti‑deformation, can be short‑term backwashing.
V. Pressure Resistance, Temperature Resistance, Chemical Properties
Working temperature
PP material: 0 - 80℃
PTFE: -20 - 120℃
Pressure resistance
Forward maximum working pressure: 0.4 MPa
Short‑term reverse pressure: ≤ 0.2 MPa
Chemical compatibility
Resistant to weak acids, weak alkalis, chlorine, oxidants, water treatment agents, suitable for pure water, sewage, seawater, and chemical fluids.
