Basic Components
1.Housing Body: Usually made of food-grade plastic (such as PP, AS, PET) or stainless steel (such as SS304, SS316).
2.Cap or Head: Contains water inlet and water outlet.
3.O-ring: Ensure sealing and prevent leakage.
4.Cartridge Slot: Internal support filter
Specifications
1.Size: Commonly available in 10-inch (10") and 20-inch (20") standard models; large fat models such as 10" Big Blue (BB), 20" Big Blue (BB).
2.Port Size: 1/4” NPT, 1/2” NPT, 3/4” NPT, 1” NPT, 1.5”, 2” and other threaded interfaces or flange interfaces.
3.Working Pressure: Generally 0.1–0.6 MPa (approximately 1–6 bar), industrial grade can withstand higher pressures (up to 1.0 MPa or higher).
4.Burst Pressure: Usually ≥ 1.2 MPa (12 bar) or above.
5.Working Temperature: Plastic shells are generally 5–45℃, and stainless steel can reach 90℃ or even higher.
6.Adaptive filter diameter: 2.5 inches (standard) or 4.5 inches (big blue).
7.Filter element length: 10 inches, 20 inches, 30 inches, 40 inches, etc. (1 inch ≈25.4mm).
8.Material: Plastics: PP, PET, AS; Metals: Stainless steel 304, 316L, etc.
9.Colors: white, transparent, blue, etc. The transparent housing facilitates observation of the filter element status.
10.Inlet/outlet direction: same side, opposite direction, vertical, etc. are optional.
Application Scenarios
1.Household water purifier (front, kitchen filtration)
2.Commercial water purification equipment (such as water dispenser and coffee machine front filtration)
3.Industrial water treatment systems (such as boilers, reverse osmosis pretreatment)
4.Agricultural irrigation filtration system
Select Suggestions
1.Select the size according to the flow rate: For example, household water is generally 10 inches or 20 inches, and industrial water is recommended for Big Blue or stainless steel.
2.Select the material according to the water quality: It is recommended to use a stainless steel shell if there are corrosive impurities or high-temperature water sources.
3.The interface size must match the pipe: avoid unstable water pressure or water seepage at the joint.
4.Whether a transparent shell is needed: It is convenient to observe whether the filter element is discolored and saturated.
5.Pay attention to certification requirements: such as NSF, FDA, ISO, etc., especially for drinking water use.
