Industrial Grade Excellence
Duplex Filter Housing Manufacturer & Supplier in India | Stainless Steel Duplex Filter Assembly
VVIOK Industry is a premier Duplex Filter Housing manufacturer and certified Duplex Filter Housing Supplier based in Ahmedabad, Gujarat, specializing in continuous uninterrupted filtration technologies for mission-critical liquid processes. Engineered with twin parallel pressure vessels interconnected by a synchronized three-way or four-way diverter ball/butterfly valve, each duplex filter assembly enables continuous round-the-clock operation. Operators can seamlessly switch process streams between chambers during maintenance, servicing, or element replacement without shutting down the main line or experiencing fluid pressure surges.
As a trusted Industrial filter manufacturer, we fabricate heavy-duty stainless steel duplex filter housing systems utilizing certified AISI 304, AISI 316, and 316L stainless steel alloys in compliance with ASME Section VIII design codes. For high-viscosity lubricating lines, fuel oil conditioning, and hydraulic power circuits, our specialized duplex oil filter housing systems provide superior particle retention, thermal stability, and collapse resistance up to 25 bar.
Additionally, our versatile product line includes high-flow ss duplex bag filter configurations and precision duplex bag filter housing systems fitted with perforated stainless steel support baskets and quick-opening swing-bolt lids. Serving refineries, chemical manufacturing plants, marine propulsion engines, power generation turbines, and pharmaceutical plants, VVIOK Industry delivers custom-engineered duplex filtration solutions with guaranteed zero-leakage diverter valves, differential pressure indicators, and 100% bypass-free fluid clarification across global industrial sectors.

Comprehensive Engineering Specifications for Stainless Steel Duplex Filter Housings:
1. Twin-Vessel Metallurgy & Design Standards:
• Pressure Vessel Shells: Precision fabricated from certified AISI 304, AISI 316, and sanitary AISI 316L stainless steel (Duplex 2205 and Carbon Steel WCB available)
• Design Standards: Engineered strictly in accordance with ASME Boiler and Pressure Vessel Code Section VIII, Division 1
• Welding Quality: 100% TIG / Argon-shielded orbital welding with pickling and passivation treatment for maximum chemical and chloride pitting resistance
• Surface Finish: Internal industrial finish or mirror-polished (Ra < 0.4 µm) for sanitary applications; glass bead-blasted or satin-buffed exterior
2. Continuous Diverter Valve & Manifold Architecture:
• Switching Mechanism: Synchronized three-way or four-way diverter ball/plug valve actuated via a single ergonomic hand lever with directional flow arrows
• Non-Stop Operation: Allows 100% full-flow diversion to the standby vessel without shutting down process lines, interrupting flow, or generating pressure surges
• Equalizing Valve Line: Pressure equalization bypass line included to equalize pressure between chambers before switching, preventing hydraulic shock
• Zero-Leakage Sealing: PTFE, Viton, or metal-to-metal seated diverter valves guaranteeing bubble-tight positive shut-off
3. Media Versatility & Filtration Basket Design:
• Bag Filter Compatibility: Accommodates standard industrial filter bags (Size 1: 7" x 17", Size 2: 7" x 32") in PP, Polyester, Nylon mesh, or PTFE
• Cartridge Filter Compatibility: Multi-cartridge internal tube sheets supporting 3, 5, or 7 rounds of DOE or Code 7 cartridges (10" to 40" length)
• Heavy-Duty Restrainer Baskets: Heavy-gauge stainless steel perforated baskets (3 mm to 5 mm perforations) lined with fine wire mesh down to 1 micron
• Positive Bypass-Free Sealing: 360-degree radial top hold-down ring ensuring 100% bypass-free fluid clarification under fluctuating flow velocities
4. Pressure, Temperature & Flow Parameters:
• Working Pressure: Standard 10 bar (150 psi); reinforced designs tested and rated up to 16 bar (232 psi) and 25 bar (360 psi)
• Hydrostatic Test Pressure: Factory tested at 1.5 times the maximum design pressure (tested up to 24 bar prior to dispatch)
• Working Temperature: From -20°C up to 150°C with Viton/EPDM seals; up to 250°C for hot thermal oil, steam, and hydrocarbon service
• Flow Capacities: From 5 m³/hr for compact fuel lines up to 450 m³/hr for heavy chemical and water cooling circuits
5. Skid Instrumentation & Maintenance Auxiliaries:
• Differential Pressure Monitoring: Top-mounted Differential Pressure Gauge (DPG) or digital DP transmitter with visual clogging indicators
• Vent and Drain Ports: Each chamber includes independent top 1/2" or 3/4" air vents and bottom clean/sludge drain ball valves
• Quick-Opening Lids: Ergonomic swing-bolt closures with heavy-duty eye nuts or counter-balanced davit arms for rapid single-operator basket servicing
