Products Description
Our duplex bag filter is designed to provide seamless, uninterrupted filtration. It integrates two independent filter chambers, allowing you to clean or replace filter bags without stopping operations. It is widely applicable to many continuous processes such as water treatment, chemical processing, and food and beverage production.
Key Features
| Feature | Advantage | Benefit to You |
| ✅ Dual-Chamber Design with Diverter Valve | Enables instant, seamless switching between filter chambers. | Zero process downtime during maintenance, maximizing productivity. |
| ✅ Independent Pressure Isolation | Allows safe servicing of one chamber while the other remains operational. | Enhanced operator safety and eliminates the need for system shutdowns. |
| ✅ High-Capacity Filter Bags | Provides a large contaminant-holding area per chamber. | Longer service cycles, reducing consumable costs and labor. |
| ✅ Differential Pressure Gauges | Visually indicates when a filter bag change is needed for each chamber. | Predictive, optimized maintenance scheduling, preventing guesswork. |
| ✅ Robust ASME-Compliant Construction | Ensures maximum reliability and longevity under high pressure/temperature. | Reduced lifecycle cost and protection of your capital equipment. |
| ✅ Leak-Free Sealing & Precision Machining | Prevents fluid bypass and ensures contaminant removal. | Consistent product quality and protection of sensitive downstream equipment. |

FAQ
Q: How do automatic changeover systems detect a bag change is needed?
A: Most use differential pressure setpoints, timer logic or contamination sensors. PLC systems can perform automatic valving and sequencing.
Q: What's the difference between duplex bag filter and duplex basket strainer?
A: Bag filters capture fine particulate with replaceable bag media; basket strainers use reusable baskets for coarser solids. Duplex versions of both share the continuous-flow advantage.
Q: What is the lead time for a custom-made duplex bag filter housing?
A: The specific lead time depends on the materials, design pressure, and level of automation. For standard 316 stainless steel units, our typical lead time is 6-8 weeks. Please contact us and provide your specific requirements so we can develop an accurate project plan and provide a quick quote.
