Single-open, double-open, threaded, flange-type, etc.

Filtration Rating (Nominal/Absolute)

Minimum particle size that can be retained

1μm, 5μm, 10μm, 20μm, 50μm, 100μm, etc.

Material

Filter cartridge skeleton, filter media, end caps, seals

Filter media: Polypropylene (PP), Polyethersulfone (PES), glass fiber, PTFE membrane, sintered stainless steel mesh, etc.; Skeleton/End caps: Polypropylene, 304/316L stainless steel; Seals: Nitrile Butadiene Rubber (NBR), Ethylene Propylene Diene Monomer (EPDM), Viton

Initial Pressure Drop

Pressure loss of a clean filter cartridge at rated flow rate

< 0.1 bar (specific value depends on flow rate and filtration rating)

Maximum Allowable Pressure Drop

Maximum forward/reverse pressure drop the filter cartridge can withstand

Usually 3 - 5 bar

Housing Material

Part of the housing in contact with liquid

Carbon steel, 304 stainless steel, 316L stainless steel, PP/FRP (corrosion-resistant)

Design Pressure/Temperature

Pressure and temperature resistance capacity of the housing

Pressure: Atmospheric pressure up to 10 bar or higher; Temperature: Depending on seals and materials, usually up to 80°C (NBR/EPDM) or 120°C (Viton)

Inlet/Outlet Connection

Pipeline interface standard

Single Unit Flow Rate

Maximum liquid flow rate a single filter can handle

50 m³/h - 1000 m³/h or higher, depending on the quantity and dimensions of filter cartridges

Design Flow Rate

Recommended operating flow rate

Usually designed at 40-150 m³/h per filter cartridge
