Industrial Bag Filter Housings | High-Efficiency Multi-Bag Solutions

At Separatech, we understand that fluid purity is the backbone of your operational efficiency. Our DL Series Industrial Bag Filter Housing are engineered to provide robust, high-volume filtration for a wide range of critical applications—from chemical processing and water treatment to oil & gas and food & beverage production.

Whether you require a compact single-bag unit or a high-capacity multi-bag system, our Industrial Bag Filter Housings are designed to deliver superior sealing, optimized flow dynamics, and exceptional structural integrity. Built for reliability in the most rigorous industrial environments, Separatech’s filtration solutions help you minimize downtime, reduce maintenance costs, and ensure consistent product quality.

Working principles of Industrial Bag Filter Housing

At the core of the DL Series Bag Filter Housing is the proven principle of surface and depth filtration. Our design ensures that your process fluid is managed with maximum efficiency through every stage of the cycle:

  1. Fluid Entry: Unfiltered liquid enters the housing through the inlet nozzle and is directed evenly into the filter bag(s).
  2. Particle Retention: As the fluid passes through the filter media, solid contaminants are trapped—either on the surface or within the bag’s depth matrix—based on your specific micron rating requirements.
  3. Bypass-Free Filtration: Our precision-engineered hold-down device creates a perfect seal between the unfiltered and filtered zones, ensuring that zero particulate “bypass” occurs.
  4. Clean Outlet: The clarified, high-purity liquid flows out through the outlet nozzle, ready for downstream processing.

Why Design Matters: Our systems feature advanced cover-lifting mechanisms and ergonomic closure designs, allowing for rapid filter bag change-outs. This minimizes labor time and keeps your facility running at peak productivity.

Our DL Series housings are designed and manufactured in accordance with strict industrial safety protocols, referencing the ASME Pressure Vessel Code to ensure maximum reliability under high-pressure conditions.
