Finding a dependable bag filter housing supplier involves looking beyond simple product catalogs to evaluate engineering capability, material verification, and logistical agility. Macrokun serves as a strategic hybrid—acting as both an elite global company supplier and a direct company factory. This dual advantage allows Macrokun to deliver robust, company customizable stainless steel filtration vessels that eliminate third-party markups, minimize supply-chain delays, and match the exact mechanical specifications of your processing facility.

Procurement and engineering teams often face a distinct challenge: traditional industrial distributors function merely as brokers. When a processing plant requires replacement equipment or a new system rollout, relying on a middleman frequently leads to miscommunicated technical specs, extended lead times, and an inability to adapt the hardware to existing footprint constraints.
By shifting your procurement strategy toward a verified company supplier that owns its production facility, you bridge the gap between procurement efficiency and engineering precision. A dedicated company factory maintains strict control over the raw material supply chain (ensuring verified SS304 and SS316L grades), utilizes certified welding procedures, and provides comprehensive pressure-testing documentation before any vessel leaves the floor. This minimizes operational risks, prevents catastrophic fluid bypass, and optimizes your facility’s long-term total cost of ownership (TCO).
When vetting a potential supplier for industrial liquid filtration housings, focus on three primary operational pillars:
In industrial fluid handling, a material failure can halt an entire production line or compromise safety. Ensure your supplier can verify:
Alloy Authenticity: Sourcing genuine, mill-certified SS304 for general utility water and chemical applications, or low-carbon SS316L for highly corrosive environments, pharmaceuticals, and marine settings.
Structural Tolerances: Precise wall thickness and heavy-duty flange ratings capable of handling systemic hydraulic shock and continuous working pressures without metal fatigue.
A capable supplier must provide diverse closure configurations to match your plant’s specific operational workflows and maintenance schedules:
Swing Bolt Designs: The industry standard for heavy-duty, high-pressure, or high-temperature safety.
V-Band Clamps: Ideal for low-to-medium pressure applications where operators require rapid, tool-free access for quick filter bag turnarounds.
Counter-Balanced Davit Arms: Essential for multi-bag vessels where the sheer weight of the heavy steel lid requires mechanical assistance for safe operator handling.
A premier supplier doesn’t just take part numbers; they analyze your system parameters. They evaluate flow dynamics, calculate clean pressure drop delta thresholds, and verify chemical compatibility to ensure the housing performs optimally within your exact hydraulic loop.
Macrokun redefines the traditional procurement paradigm by operating as a direct-to-market company factory and full-service company supplier. We eliminate the administrative overhead and logistical delays associated with secondary brokers, offering a transparent, highly agile pipeline from raw steel to your facility’s loading dock.
We understand that standard, off-the-shelf catalog units rarely align perfectly with pre-existing plant infrastructure. Macrokun specializes in company customizable designs built to integrate seamlessly into your current layout, offering modifications such as:
Custom Nozzle Orientations: We configure side-in/bottom-out, loop-flow, straight-through, or custom-angled inlets and outlets to match your existing pipe headers exactly.
Sanitary and High-Purity Finishes: From standard bead-blasting for utility lines to precision electropolishing (achieving internal surface roughness values below 1.4 µm) for food, beverage, and life sciences applications.
Integrated Sensor & Instrument Ports: Pre-fabricated ports for differential pressure gauges, vent valves, sample taps, and automated purge lines to easily connect with your facility’s centralized control framework.
Skid-Mounted Duplex Systems: Engineering parallel multi-vessel systems equipped with directional 3-way valves, enabling continuous, uninterrupted processing by diverting fluid flow during bag changes.
The matrix below highlights the foundational specifications across our standard vessel configurations. Every parameter listed can be modified through Macrokun’s customized production stream.
| Housing Configuration Type | Filter Bag Capacity | Nominal Flow Rate (m³/h) | Available Metallurgy | Maximum Working Pressure (Bar) | Standard Connection Profiles |
| Single-Bag (Size #1 / #2) | 1 Bag | 20 – 45 | SS304, SS316L | 6 / 10 / 16 | 1.5″ – 3″ ANSI Flange / NPT Thread |
| Mini-Bag (Size #3 / #4) | 1 Bag | 6 – 12 | SS304, SS316L | 6 / 10 | 1″ – 1.5″ Male Thread / Tri-Clamp |
| Multi-Bag (Low-Volume) | 2 – 4 Bags | 80 – 180 | SS304, SS316L, Carbon Steel | 10 / 16 | 3″ – 6″ ANSI Flange |
| Multi-Bag (High-Volume) | 5 – 12+ Bags | 220 – 500+ | SS304, SS316L | 10 / 16 / 20 | 6″ – 12″ ANSI or DIN Flange |
| Sanitary Ultra-Pure | 1 Bag | 15 – 40 | SS316L (Internal Ra < 1.4 µm) | 6 / 10 | Sanitary Tri-Clamp (Ferrule) |
The Sourcing Challenge: A procurement manager for a North Sea drilling platform needed to replace heavily corroded seawater injection housings. Standard suppliers quoted a 16-week lead time for specialized alloys, which risked a costly production slowdown.
The Macrokun Solution: As a nimble company supplier with deep raw material reserves, Macrokun leveraged its company factory to fast-track production of custom SS316L single-bag vessels with internal protective fluoropolymer linings. The heavy-duty housings were delivered weeks ahead of schedule, withstanding aggressive chloride environments and protecting the downstream system.
The Sourcing Challenge: An automotive coatings plant required a multi-bag filtration unit for high-viscosity resins. The factory’s rigid footprint meant standard top-inlet vessels would not clear overhead structural beams.
The Macrokun Solution: Macrokun’s design team provided a company customizable low-profile, side-inlet multi-bag housing with an integrated low-clearance davit assembly. This design allowed operators to replace filter bags quickly and safely within their limited vertical space, keeping production moving.
The Sourcing Challenge: A major dairy exporter required a filtration stage to remove particulates from whey streams. The supplier had to guarantee zero stagnant zones within the housing where bacteria could colonize, along with full sanitary certification.
The Macrokun Solution: Macrokun manufactured a bespoke sanitary housing featuring an internally electropolished finish, a inverted-dome bottom to ensure total drainage, and sanitary tri-clamp connections. The unit integrated seamlessly into the plant’s automated Clean-In-Place (CIP) cycle, easily passing strict food safety audits.
Sourcing directly from a company factory like Macrokun gives you clear insight into material tracing, direct communication with the engineers building your equipment, and significantly reduced lead times. It also removes the multi-tier distributor markups, giving you the best possible value for your capital expenditure.
Every housing manufactured in our factory undergoes rigorous hydrostatic pressure testing—typically at 1.3 to 1.5 times the intended design pressure—to ensure total integrity of the welds and seals. We supply complete material test reports (MTRs) and pressure certifications upon request.
For aggressive chemical processing, Macrokun offers company customizable upgrades, including high-performance fluoropolymer internal coatings (such as PTFE, PFA, or ETFE) and specialized chemical-resistant elastomer gaskets (Viton, EPDM, or Kalrez) to prevent seal degradation and structural corrosion.
Yes. By providing our team with basic dimensional layouts, inlet/outlet centerlines, and flange styles, Macrokun can reverse-engineer and customize a drop-in replacement housing. This eliminates the need for expensive, time-consuming field piping modifications.
Because Macrokun functions as a fully integrated factory, we move quickly. Minor customizations on single-bag vessels typically ship within 2 to 3 weeks, while complex, engineered-to-order multi-bag skids or automated systems are generally ready in 4 to 6 weeks, depending on the complexity of the design.
