Stainless Steel Multi-Bag Filter Housing – Flange Type High Flow Series
Stark Multi-Bag Filter Housing (STK5 Series) is engineered for high-volume industrial filtration. Featuring a heavy-duty flange closure, this series supports 1 to 5 filter bags, handling flow rates up to 100 m³/h for centralized water treatment systems.
Product Description
Centralized High-Volume Filtration.
For industrial applications requiring flow rates exceeding 40 m³/h, running multiple single-bag filters in parallel is inefficient and space-consuming. The Stark STK5 Multi-Bag Series consolidates up to 5 filter bags into a single, compact vessel.
This design significantly reduces the installation footprint and piping complexity. To ensure safety under high pressure, the vessel utilizes a Bolted Flange Closure, providing superior sealing integrity compared to clamp-style housings for large-diameter tanks.
Dimensions & Davit Arm Specs:
Larger models (3-bag and above) are equipped with a davit arm for easy cover lifting. For detailed flange connection drawings (ANSI/DIN) and footprint dimensions, please reference the technical data at our manufacturing division:

Applicable Industry
- Central Water Systems:
Acts as the primary filtration station for entire factories, handling massive flow rates (up to 100 m³/h) in a single vessel. - Desalination Pre-Filtration:
Essential security filtration for large-scale SWRO plants, protecting high-pressure pumps and membranes from particulate damage. - Cooling Tower Full-Flow:
Capable of filtering the full circulation flow of large cooling towers to prevent heat exchanger fouling.
Advantage One
Multi-Bag Efficiency
The STK5 Multi-Bag Design allows you to replace a bank of parallel single filters with just one unit. For example, the STK5-Φ550 model holds 5 bags, offering the same capacity as 5 individual housings.This drastically reduces piping costs, minimizes leak points, and simplifies the maintenance process for operators.Advantage TWO
Heavy-Duty Flange Sealing
Safety is paramount when dealing with large volumes of pressurized liquid. The STK5 series employs a standard Bolted Flange Closure mechanism.This robust design provides the highest safety factor against pressure surges and water hammer, making it the preferred standard for chemical processing and heavy industrial applications.Related Products
