Duomax Compact™ Double Cone Strainer Series: High-Area Inline Filtration for Tight Spaces
When you are designing a new piping system or prepping a facility for commissioning, protecting your downstream equipment is critical. Stray debris, installation scale, and welding slag can cause immediate and costly damage to pumps, compressors, and precision instruments.
However, engineering layouts often present a major hurdle: a lack of physical space. When a pipeline flange sits directly before a sharp elbow, a valve, or a pump intake, you simply do not have the horizontal space required to install a standard elongated conical filter.
To solve this exact engineering bottleneck, we have launched our new range of Duomax Compact™ Double Cone Strainers.
By utilizing a nested, dual-cone profile, this innovative series packs a massive filtration surface area into an incredibly short installation length. You get the ultra-low pressure drop of a full-sized cone filter within a tight, space-saving footprint.

The Engineering Advantage of the Duomax Compact™ Shape
The primary challenge with compact pipelines is that shortening a standard filter usually means choking your fluid flow. If you reduce the surface area of the mesh, your system experiences a rapid spike in flow resistance and differential pressure.
The Duomax Compact™ Double cone strainer design avoids this compromise entirely through its nested geometry.
- Short Overall Length: The dual-cone configuration allows the strainer to sit completely inside short pipeline sections without extending deep into downstream fittings or bends.
- Massive Filter Surface Area: By splitting the fluid path across two concentric, nested cones, the strainer maximizes the available filtration area, ensuring a long service life and high dirt-holding capacity.
- Low Flow Resistance: Because the fluid has a much larger surface area to pass through, initial pressure loss is kept to an absolute minimum, ensuring your system runs at peak hydraulic efficiency.
This balanced combination makes the series an exceptional option for collision protection during the critical startup and commissioning phases of industrial plants.
Universal Flange Integration and Precision Sealing
Every Duomax Compact™ Double cone strainer is custom engineered to clamp cleanly between standard industrial welding neck flanges. We adapt the outer structural ring to match the exact pressure rating and sealing face layout of your existing pipe network.
The series integrates seamlessly with major international pipeline standards:
- European Standards: Fully compatible with DIN EN 1092-1 flange layouts.
- American Standards: Built to match ASME B16.5 and B16.47 dimensions and pressure classes.
Custom Sealing Face Adaptations
To ensure a completely leak-proof installation, we match the sealing surfaces of the strainer to your specific gasket specifications. We routinely manufacture units to fit standard Form B1 / B2 and Raised Face (RF) profiles, and we can easily adapt the design to fit specialized Ring-Type Joint (RTJ) grooves or Form C / D (Tongue and Groove) connections.
Multi-Media Versatility and Proactive Engineering Support
Multi-Media Versatility and Proactive Engineering Support Industrial processes rely on diverse fluids and gas streams. Because of their robust structural build and flexible wire mesh choices, Duomax Compact™ strainers are highly versatile and can be utilized across a wide variety of process media:
- Liquids: Water treatment, chemicals, hydrocarbons, and cooling loops.
- Gases: Natural gas lines, compressed air, and process air infrastructure.
- Vapors: Low-pressure steam systems and thermal processes.
Proactive Pressure Drop Calculations
To take the risk out of your plant planning phase, our engineering team provides precise differential pressure modeling before fabrication even begins.
We analyze your specific flow rates, fluid viscosity, and target mesh size to calculate the expected pressure drop during real-world operation. This allows us to determine the ideal structural burst pressure rating for your strainer, ensuring it stands up to your system’s maximum allowable differential pressure without risking structural collapse.

Frequently Asked Questions (FAQ)
1.How does the Duomax Compact™ save space compared to a standard conical strainer?
A standard conical strainer uses a single, long cone that extends deep down the center of the pipe. If you have an obstacle—like a valve, pump intake, or a sharp 90 0
elbow—right after the flange, a standard cone will physically hit it. The Duomax Compact™ solves this by nesting two smaller, concentric cones inside one another. This design delivers a large, multi-tiered surface area within a fraction of the horizontal length, allowing it to fit into tight spatial bottlenecks safely.
2.Can the Duomax Compact™ be customized for highly specialized flange surfaces?
Yes. Every pipeline has unique sealing requirements based on its operating pressure and chemical media. While we standardly manufacture units for common Raised Face (RF) and Form B1 / B2 faces, our engineering team can easily customize the outer structural ring to match highly specialized layouts. This includes high-pressure Ring-Type Joint (RTJ) grooves and precision Form C / D (Tongue and Groove) sealing configurations.
3.What media types can run through a Duomax Compact™ strainer?
This series is highly versatile and built to handle three distinct states of fluid matter:
- Liquids: Process water, chemical solutions, cooling fluids, and fuels.
- Gases: Compressed air, natural gas, and technical process gases.
- Vapors: Saturation streams and low-to-medium pressure steam applications
We adjust the base metallurgy and wire mesh sizes to match the exact temperature, corrosiveness, and density of your specific media.
4.Why should I get a differential pressure calculation during the planning phase?
Getting a calculation early ensures your pipeline operates safely and efficiently. If a strainer is under-engineered for a high-velocity line, the fluid force can cause the mesh to collapse. By analyzing your flow data during the planning phase, we calculate the expected pressure drop across the strainer. This lets us verify the exact mechanical burst pressure required for your design, keeping your operations safe under real-world debris loading.
5.Is the Duomax Compact™ intended as a permanent or temporary filtration solution?
It can be used for both, depending on your system’s debris levels. It is highly popular as a high-capacity temporary commissioning filter because it protects sensitive new equipment inside compact piping skids. However, because of its robust stainless-steel construction, thick perforated support core, and resistance to mesh fluttering, it is completely suitable for permanent operation in systems where the fluid is generally clean and only requires seasonal or intermittent maintenance checks.
