FiltEdge’s Filter Vessels Manufacturing Standards
Leakage Control: Provides you with a finish-flat groove seal that keeps your line leak-free, even under high-pressure fluctuations.
Pressure Safety: Strictly perform hydraulic pressure stabilization tests at 1.5 times the design pressure for you, and define structural strength in accordance with ASME standards to eliminate your safety hazards.
Material Quality: MTC certified stainless steel is selected for you and combined with pickling and passivation of the entire line to eliminate material adulteration and avoid secondary contamination of your system.
What is FiltEdge’s Filter Vessels?
FiltEdge’s Filter Vessels, also known as Filter Housing or Filter Casing, are the heavy-duty pressure devices in your filtration system that hold the filter media and keep your process safe.
We offer precision filtration options from 0.1μm to 2000μm that not only withstand aggressive and high-temperature fluids, but also precisely match your existing piping with flanged, threaded, or sanitary connections. Optimized flow path design effectively reduces pressure drop, helping you cope with high-flow conditions with ease.
Whether you’re treating large-scale industrial water, refining high-value chemicals, or ensuring the purity of your food and beverage, the FiltEdge maintains consistent filtration even with fluctuating flow rates.
Filter Vessel Selection & Types
Whether you’ re handling high volumes of industrial water, fine chemicals, or complex oil/water separations, FiltEdge’s line of Filter Vessels can help you quickly find the right fit for your piping and pressures.
And if standard sizes don’t fit, our engineers can customize filter vessels for your specific process.
With a flow rate of 15-40m³/h, support for higher pressures (>1.0MPa) and top entry construction, this is a compact choice for your intermittent production.
2-32 bags are available with flow rates of 1000 m³/h or more. The quick-open swing-arm design significantly reduces your maintenance effort during continuous high-flow operation.
Connecting two vessels in parallel via a switching valve lets you change the filter bag without stopping production for zero downtime.
With an accuracy of 0.5 μm and a mirror finish with a Ra < 0.4 μm, they are fully compliant with ASME standards and guarantee the cleanliness of your fine chemical processes.
A single cartridge can provide more than 20 times the flow rate of a conventional cartridge (up to 80 m³/h). This allows you to handle a larger flow rate in a smaller tank, saving you space and maintenance time.
Heavy-duty pressure vessel designed to decolorize and deodorize your pre-treatment process, laying the foundation for your subsequent precision filtration.
For your oil-water or gas-liquid separation needs, the built-in precision coalescer internal parts provide you with pure media output even under complicated working conditions.
Filter Vessels Process
Heavy-Duty Support Basket
We understand that poor quality baskets are susceptible to deformation under pressure fluctuations, which can lead to accidental rupture of your filter bag. For high pressure differentials, FiltEdge uses 2.0mm thick SS316L punched and molded into a single piece with a rigorous surface polishing and deburring process. This rigid structure provides solid support for your filter bag, eliminating the risk of breakage and extending the life of your consumables at the source.
Positive-Seal Hold-Down Ring
Precision manufactured stainless steel three-jaw/ring hold-down mechanism. The vertical weight of the lid closure, combined with the “positive pressure” of the fluid itself , forces the filter bag collar to fit 100% against the base, providing you with the ultimate seal with zero bypass leakage.
Customized Filter Vessels Interfaces
Piping in industrial sites varies greatly, and mismatched equipment means delays and additional retrofit costs. As a manufacturer, FiltEdge offers 100% flexibility in customizing interfaces, ensuring that Filter vessels can be seamlessly integrated directly into your existing piping system at .
Versatile Standards: Whether your system utilizes ANSI (American Standard), DIN (German Standard), or JIS (Japanese Standard), we can match it.
Connections: Industrial flanges, sanitary Tri-clamp (quick release), and high-seal NPT/BSP threads are available.
Flow layout: Side-in, Bottom-out, Side-in-Side-out or Bottom-in-Bottom-out. All you need to do is provide the drawings and we will do the rest of the structural optimization.
Quality Control and Testing for Filter Vessels
Safety and leak tightness are the bottom line for pressure filter vessels, and every unit from FiltEdge goes through a rigorous and standardized testing process before delivery to ensure that it meets the requirements of your application:
Penetrant Testing (PT): Penetrant testing is performed on all critical weld seams. Our specialized coloring process captures any subtle surface openings and ensures that you get a structurally sound shell with tight welds.
1.5x Hydrostatic Strength Testing: Every filter vessel is pressure tested for a minimum of 30 minutes at 1.5 times the design pressure. We keep pressure curves or test records for you to ensure that the pressure safety of the filter vessel is not in doubt on your production line.
Ra Surface Roughness Measurement: For demanding industries such as pharmaceuticals and food, we offer a mirror polishing service with a Ra value report (up to Ra < 0.4μm). This helps you to effectively avoid material walling and eliminate the risk of secondary contamination.

Industry Applications of Filter Vessel
Filtration is not just about stopping contaminants, it’s about keeping your entire production line running efficiently, and FiltEdge has the right materials and construction solutions for the energy and chemical, bio pharmaceutical and food, electronics and plating, automotive and paint, and municipal and environmental industries, to name a few.
Faced with challenging corrosive environments such as strong acids and alkali, FiltEdge can provide special fluorine lining (PTFE/PFA Lining) or high grade alloys according to the composition of your media, completely solving the downtime hazards caused by corrosion perforation.
In reverse osmosis (RO) system fore-hearths, where unstable water quality can quickly destroy expensive membrane modules, the FiltEdge high-flow filtration system is designed for high throughput conditions, providing a precise retention barrier for your RO membranes through an extremely low initial system pressure drop and a high dirt-trapping space. Ensuring that the fluid entering the membrane module meets stringent SDI specifications significantly extends the cleaning cycle and life of expensive membrane elements.
For sanitary applications, confirm material compatibility, applicable food-contact documentation and cleaning requirements. The stated internal surface finish of Ra < 0.4 μm and CIP suitability require confirmation for the selected vessel and process; food safety compliance is not an unconditional product guarantee.
For highly viscous liquids and volatile media, our quick-open cover design dramatically reduces your downtime for cleaning. Positive sealing ensures that every drop of your finished product is never wasted, even when working with high-value coatings.
