Product Overview
Oil Filtration Machine selection logic for fluid purity applies equally to chemical liquid, and the absorbent cotton filter element version of the wound family is built for media that PP yarn cannot comfortably carry. It sits under the Water Filter Element catalogue: absorbent-cotton yarn on a stainless steel center rod, available at 1, 5 and 10 μm, maximum operating temperature 82 ℃, maximum PSID 2.8 Bar at 65 ℃. Glass-fiber yarn grade extends the chemical-compatibility window for organic solution.

Chemical Solvent Scenario
In fine chemical plants producing coating resin and adhesive, process liquid passes through reactors and settling tanks, carrying catalyst fines and pigment particles that attack ordinary polypropylene media. The glass fiber wound cartridge filters organic solution and alkaline liquid where steel-core construction avoids rust shedding into the batch. In pharmaceutical and food handling, the cotton yarn version is accepted for water, oil and beverage contact because the stainless steel center rod eliminates plastic-core swelling risk. Plants running an Industrial Oil Purification Equipment line often use this grade on the auxiliary chemical dosing loop, keeping dosing solution free of grit before injection.
Product Advantages
Stainless steel center rod resists pressure collapse and avoids the swelling that a plastic core shows in hot solvent. Cotton yarn carries food-grade and beverage duties, while glass fiber yarn extends solvent compatibility. The 1, 5 and 10 μm ratings cover fine polish stages where a coarser depth cartridge leaves particles behind. Deep winding gives small pressure drop and large pollutant-carrying capacity, and the element seats on standard fin or thread connections.
Manufacturer And Factory Strength
Our workshop keeps cotton, PP and glass-fiber yarn stocks side by side, so one purchase order can mix media grades for different process tanks. Each cartridge is checked for winding tightness and seal seating before packing, and material-compatibility records are kept per batch. For high-flow chemical duty, engineers may pair this element with a High Flow Filter Cartridge downstream; project support is available when you contact our engineering team.
FAQ
Q1: Why use a stainless steel center rod instead of PP?
A1: In organic solvent and hot liquid, a plastic core can swell or soften; stainless steel keeps dimensional stability under pressure cycling.
Q2: Which yarn grade for strong alkali solution?
A2: Cotton yarn grade handles water, oil, alkali and beverage; glass-fiber grade is selected for aggressive organic solution, confirmed by compatibility check.
Q3: What does the 2.8 Bar PSID rating mean?
A1: It is the recommended maximum differential pressure before change-out at 65 ℃; exceeding it risks yarn pack collapse.
Q4: Can it be used in drinking water filling lines?
A1: Cotton grade is suitable for beverage and medicine contact; confirm food-contact compliance documentation at order.
Q5: Are 20 μm and 50 μm available in this series?
A1: This cotton/glass series lists 1, 5 and 10 μm; coarser ratings use the PP wound grade described in Article 1.
