Selecting the right bag filter housing manufacturer requires balancing structural integrity, material compliance, and engineering flexibility. Macrokun stands out as a premier direct-to-market company factory and trusted company supplier, specializing in high-performance, company customizable stainless steel bag filter housings. By eliminating middlemen, Macrokun delivers industrial-grade filtration vessels engineered precisely to your flow rates, pressure demands, and chemical compatibility requirements, ensuring long-term operational efficiency and a lower total cost of ownership.
In industrial liquid filtration, the bag filter housing is the unsung hero of process safety, product clarity, and equipment protection. Whether you are filtering municipal water, processing volatile chemicals, or clarifying beverages, the housing must withstand intense hydraulic pressures and corrosive environments without failing.
Partnering with a dedicated company factory rather than a generic distributor ensures that your equipment is built from verified materials (such as SS304 or SS316L) and meets stringent welding standards. A direct manufacturer gives you transparent traceability on raw materials, expert engineering support, and the agility to adapt designs to existing pipe layouts—saving your facility thousands of dollars in retrofitting costs.
To optimize your filtration process, it is vital to understand the structural and mechanical elements that differentiate a premium vessel from a substandard one.
Industrial environments demand resilience. Premium manufacturers use high-grade stainless steel to prevent rust, pitting, and chemical degradation.
SS304: Ideal for commercial water treatment, food and beverage, and light industrial applications.
SS316L: The gold standard for pharmaceutical, marine, and highly corrosive chemical applications due to its superior molybdenum content.
Bypass is the enemy of filtration. If liquid escapes around the edge of the filter bag, contamination passes straight to your end product. High-quality housings feature precision-engineered hold-down devices that compress the bag ring tightly. Closure types include:
Swing Bolt Closures: Designed for high-pressure and heavy-duty applications, offering robust safety.
V-Clamp Closures: Ideal for low-to-medium pressure systems where quick, tool-free bag changes are prioritized.
Quick-Open Handwheel Mechanisms: Perfect for multi-bag systems where minimizing maintenance downtime is critical.
A well-designed housing ensures even fluid distribution across the filter bag surface. This prevents localized blinding of the filter media, extends bag life, reduces pressure drop ($\Delta P$), and lowers energy consumption across your feed pumps.
When looking for an authorized company supplier, generic off-the-shelf solutions often force you to compromise on your system’s design. This is where Macrokun redefines industrial sourcing. As an established manufacturing powerhouse, Macrokun combines the technical precision of an advanced company factory with the global logistics of an experienced supplier.
No two processing plants are identical. Macrokun recognizes that unique spatial constraints, fluid viscosities, and connection types require bespoke solutions. Our engineering team provides fully company customizable options, including:
Custom Inlet/Outlet Configurations: Choose between side-in/bottom-out, loop-flow, or straight-through piping layouts.
Tailored Surface Finishes: From standard sandblasting and mechanical polishing to high-purity electropolishing for sanitary pharmaceutical applications.
Multi-Vessel Skid Systems: Engineering parallel multi-bag duplex systems that allow for continuous filtration without shutting down your line during bag replacements.
Specialized Fitting Integrations: Pre-installed pressure gauges, vent valves, sample ports, and electronic differential pressure sensors to sync seamlessly with your facility’s automated control systems.
To streamline your procurement process, the table below outlines the standard engineering parameters offered by Macrokun. All parameters can be adjusted via our customization pipeline.
| Housing Model Type | Bag Quantity | Max Flow Rate (m3/h) | Available Materials | Max Working Pressure (Bar) | Connection Sizes & Types |
| Single-Bag (Size 01 / 02) | 1 Bag | 20 – 45 | SS304, SS316L | 6 / 10 / 16 | 1.5″ – 3″ Flange / Thread |
| Mini-Bag (Size 03 / 04) | 1 Bag | 6 – 12 | SS304, SS316L | 6 / 10 | 1″ – 1.5″ Thread / Tri-Clamp |
| Multi-Bag (Low Capacity) | 2 – 4 Bags | 80 – 180 | SS304, SS316L, Carbon Steel | 10 / 16 | 3″ – 6″ ANSI Flange |
| Multi-Bag (High Capacity) | 5 – 12+ Bags | 220 – 500+ | SS304, SS316L | 10 / 16 / 20 | 6″ – 12″ ANSI / DIN Flange |
| Sanitary High-Purity | 1 Bag | 15 – 40 | SS316L (Internal Ra < 1.4 µm) | 6 / 10 | Tri-Clamp (Ferrule) |
The Challenge: A coastal desalination facility faced severe saltwater corrosion on their pre-RO (Reverse Osmosis) filtration housings, leading to micro-fissures along standard welds.
The Macrokun Solution: Macrokun acted as their dedicated company supplier, delivering custom SS316L multi-bag filter housings with specialized internal epoxy coatings and passivated welds. The robust design successfully resisted chloride pitting, extending the equipment lifespan by 300%.
The Challenge: A rapidly growing craft brewery needed a clarification filter but had extremely limited floor space and required strict sanitary connections to prevent bacterial contamination.
The Macrokun Solution: Utilizing Macrokun’s company customizable design services, the factory manufactured a compact, vertically stacked single-bag housing with an internal electropolished finish ($R_a < 1.4\,\mu\text{m}$) and tri-clamp sanitary fittings. It fit perfectly into their tight layout while passing stringent food safety audits.
The Challenge: A petrochemical plant required continuous filtration of highly viscous polymers at 140°C, meaning the process could not be stopped for maintenance.
The Macrokun Solution: Macrokun engineered a custom, automated duplex multi-bag filter housing skid with a jacketed heating layer to maintain fluid temperature. When one housing reached its dirt-holding capacity, the system automatically diverted flow to the secondary housing, allowing seamless, zero-downtime operations.
Buying directly from a company factory like Macrokun gives you direct line communication with the engineers designing your equipment. It eliminates distributor markups, ensures 100% material traceability, provides faster lead times for custom builds, and offers precise post-sale technical support.
Yes. Macrokun’s factory fabricates vessels capable of meeting rigorous industrial metrics. Our customizable options ensure that wall thicknesses, weld penetrations, and pressure tolerances are strictly aligned with your regional safety mandates and operational parameters.
The choice depends primarily on your required flow rate and solids loading. Single-bag housings are excellent for batch processes or lower flow rates (up to 45 $m^3/h$). For high-flow continuous operations or liquids with heavy particulate concentrations, a multi-bag housing is necessary to prevent rapid clogging and frequent process shutdowns.
For aggressive chemicals, Macrokun offers custom fluoropolymer linings (such as PTFE or PFA), alternative O-ring materials (Viton, EPDM, or Kalrez), and heavy-duty swing-bolt closures to guarantee maximum chemical compatibility and worker safety.
Because Macrokun controls the entire manufacturing pipeline as a direct factory, turnaround times are highly optimized. Standard modifications typically take 2–3 weeks, while complex, engineered-to-order multi-vessel skids are completed within 4–6 weeks, depending on materials and design complexity.
