Stainless Steel Top Entry Bag Filter Housing – Premium Gooseneck Series
Stark Top Entry Bag Filter Housing (STK4 Series) features a premium “Gooseneck” design for vertical Top-In/Bottom-Out flow. Constructed with heavy-duty 2.0mm-2.5mm stainless steel, this vessel ensures absolute hermetic sealing and minimal pressure drop for high-precision filtration.
Product Description
The Ultimate Design for Precision Filtration.
The Stark STK4 Top Entry Series represents the pinnacle of bag filtration design. Unlike side-entry models, the fluid enters vertically through the “Gooseneck” top lid, pressing directly down into the filter bag. This eliminates turbulence and ensures uniform flow distribution, significantly extending filter bag life.
Most importantly, this design utilizes the fluid pressure to reinforce the seal on the bag collar, creating a Self-Tightening Hermetic Seal that guarantees zero bypass, making it the only choice for strict micron-rated applications.
Flow Simulation & Casting Specs:
The integrated cast top lid provides a smooth internal finish with no dead angles. For flow simulation data, pressure drop comparisons, and detailed installation drawings, please reference the technical data at our manufacturing division:

Applicable Industry
- Pharmaceutical Pre-Filtration:
The sanitary top-entry design minimizes dead legs and is easy to clean (CIP), making it ideal for pharmaceutical process water. - Microelectronics:
Used for filtering ultra-pure water where zero particle bypass is critical to protect sensitive semiconductor wafers. - High-Grade Automotive Paint:
The smooth laminar flow prevents micro-bubbles and ensures absolute filtration of topcoats and clear coats.
Advantage One
Top-Flo “Gooseneck” Design
The distinctive Gooseneck Geometry allows fluid to enter the vessel from the top and flow vertically through the filter bag.This streamlined path reduces fluid turbulence and impact velocity, which not only prevents bag tearing but also ensures even utilization of the entire filter surface area.Advantage TWO
Absolute Hermetic Seal
Precision is nothing without a good seal. In the STK4 series, the top cover applies direct downward pressure onto the filter bag ring.As internal pressure increases, the seal actually tightens further (Self-Sealing Effect), providing the highest level of bypass protection available in a bag filter housing.Related Products
