Product basic parameters and core structure
1. Equipment models: Single bag filter covering multiple specifications such as LF-1A, LF-2A, LF-2B, LF-4A, LF-5A, and LF-6A. Different models correspond to differentiated external dimensions and interface specifications, and are suitable for different flow conditions.
2. Main material: Imported PPH and PVDF integrated shell, without welding seams, to prevent weld corrosion and leakage, suitable for strong corrosive media such as acid and alkali, solvents, etc.
3. Filter bag specifications: Supports 1 #, 2 #, 4 #, and 5 # standard filter bags; The filter bag can be made of polypropylene, polyester, nylon, polyamide, polytetrafluoroethylene, polyester and other filter materials, with a wide range of filtration accuracy options.
4. Interface specifications: The inlet and outlet can be selected from 1-1/2 inches to 2-1/2 inches, with flange connection and easy installation and docking.
5. Sealing structure: 360 ° fully enclosed sealing design ensures no bypass flow between the filter bag and the shell, achieving high-precision filtration and preventing impurities from short circuiting and penetrating.
6. Core structure: Integrated molded cylinder body, quick opening top cover, filter bag support basket, sealing pressure ring, inlet and outlet flanges, with a simple structure and no exposed corrosive metal components.
7. Operating principle: The liquid to be filtered enters the cylinder through the inlet of the filter. Under pressure, the liquid passes through the filter bag from the outside to the inside. Impurities such as solid particles, colloids, paint residue, and activated carbon particles in the liquid are trapped inside the filter bag. The clean fluid passes through the filter bag and is discharged from the outlet; After the pressure difference of the filter bag increases, the top cover can be opened without tools, and the filter bag can be replaced directly to complete the maintenance operation.
8. Shell characteristics: The inner wall is smooth and flat, not easy to hang materials, and easy to clean; Integrated molding without welding points, achieving zero leakage and avoiding the risk of weld corrosion and damage.
9. Operating characteristics: Zero tool cover opening design, quick and convenient replacement of filter bags, reducing downtime for maintenance.
10. Factory inspection: Each device undergoes water pressure leakage testing, sealing performance testing, and is accompanied by dimensional drawings and product manuals to meet the acceptance standards of chemical and electronic projects.


Applicable industries and equipment operating conditions of the product

Metal processing industry: Metal processing fluid, hydraulic oil, and cleaning mixture filtration are used to remove processing debris and impurities, and are used for fluid filtration in copper foil and aluminum foil production lines to reduce residual impurities on the surface of parts and extend equipment service life.
2. Electronic semiconductor industry: PCB electroplating nickel plating, electroplating gold plating, etching, developing, acid alkali cleaning and other chemical liquid filtration; Chip etching groove, photo polishing, high-purity water pre filtration, protect precision electronic production processes and reduce defective products.
3. Chemical industry: acid liquor, alkali liquor, organic solvent filtration, catalyst recovery, removal of lotion, dispersion, resin colloid, activated carbon particles, paint agglomerate, suitable for purification of various strong corrosive chemical fluids.
4. Coating and ink industry: resin, plastic, ink, coating oil, polymer filtration, used for filtering canned coatings, paper coatings, high-purity inkjet raw materials, removing paint residue and agglomerated particles, and improving the smoothness of coating products.
There is a clear distinction between one-piece single bag filters and carbon steel basket filters. Basket filters are commonly used for coarse filtration in pipelines to intercept large particle impurities; The PPH/PVDF single bag filter is mainly used for precision filtration of corrosive chemical liquids, with higher filtration accuracy and acid and alkali resistance of the shell. It is more suitable for process sections such as electronics and fine chemicals that have strict requirements for medium cleanliness and corrosion prevention.
Core competitive advantages of the product
1. One piece molding with no welding structure, zero leakage risk. The cylinder is molded as a whole, without the problem of weld corrosion and cracking. It is suitable for corrosive fluids such as acids, alkalis, and solvents, and runs stably for a long time.
2. The inner wall is smooth and easy to clean, reducing material hanging on the wall. The smooth inner wall of the cylinder is not easy to adhere to colloids and paint residue, making cleaning simple and avoiding cross contamination of materials from different batches.
3. 360 ° sealed structure, reliable filtration accuracy. Seal the entire perimeter to prevent fluid bypass short circuits. All liquids must be filtered through filter bags to ensure effective impurity interception.
4. Zero tool maintenance, easy replacement of consumables. The quick opening structure of the top cover eliminates the need for tools such as wrenches, allowing for quick replacement of filter bags and reducing downtime on the production line.
5. High polymer anti-corrosion material, temperature resistant and corrosion-resistant. PPH and PVDF materials can resist most acids, alkalis, and organic solvents, solving the pain point of metal shells being easily corroded and contaminated by media.
6. Modular selection, easy integration. Multiple models and sizes are available, which can be used alone or combined into a complete filtration system, suitable for process requirements ranging from small to medium flow rates.
Source factory production advantage
1. Polymer molding process with stable quality. Imported PPH and PVDF raw materials are used for integrated processing. The shell has uniform strength, excellent aging resistance and chemical corrosion resistance.
2. Full range of models in stock reserve. The regular models of LF series single bag filters have sufficient inventory and can quickly deliver orders for projects such as electronics, fine chemicals, coatings, etc.
3. One stop supply of supporting consumables. We can provide spare parts such as filter bags and sealing gaskets with different precision and various materials, which are easy to replace and purchase in the later stage.
4. Customized support. We can customize filter bag materials and interface standards according to customer flow and medium corrosion characteristics, and adapt them to special process conditions.
5. Improve technical support. Provide selection calculation, installation guidance, supporting technical materials in both Chinese and English, and support foreign trade export projects.
6. Strict factory inspection. Each device is subjected to pressure leakage testing to ensure reliable sealing of the shell and meet the requirements for chemical explosion-proof and clean workshop matching use.
Frequently Asked Questions (FAQ)
Q1: What is the filtering working principle of the integrated single bag filter?
A: The fluid to be processed enters the filter chamber and passes through the filter bag under pressure. Solid particles, colloids, and suspended solids inside the liquid are trapped inside the filter bag, while clean fluid flows out from the outside of the filter bag; When impurities accumulate and cause an increase in pressure difference between the inlet and outlet, opening the top cover and replacing the filter bag can restore the filtering capacity.
Q2: What are the differences in the applicable scenarios of PPH and PVDF material shells?
A: PPH is suitable for most room temperature acidic and alkaline liquid medicines, with high cost-effectiveness; PVDF has stronger solvent resistance, high temperature resistance, and strong corrosion resistance, making it suitable for harsh working conditions such as strong oxidants and high-temperature corrosive chemicals, and relatively higher costs.
Q3: How often is the filter bag replaced?
A: The replacement cycle depends on the fluid impurity content. Clean chemical raw materials can be replaced in several months; Coatings and media containing a high amount of suspended particles need to have their replacement cycle shortened according to the pressure difference. When the system pressure difference reaches the set upper limit, it is recommended to replace the filter bag.
Q4: Can a single bag filter be used to filter organic solvents?
A: Okay. Using PVDF shell with PTFE filter bag can adapt to most organic solvent filtration; Before selecting, it is necessary to verify the chemical compatibility between the medium, shell, and filter bag materials.
