Engineered stainless steel filter nozzles for rigorous media retention
MutualFilter manufactures custom wire mesh and wedge-profile filter nozzles designed for uniform liquid collection, low pressure drop, and non-clogging performance in industrial vessels.
Robust welded construction engineered to withstand high backwash pressures and thermal fluctuations without media loss.
Critical filtration applications
Tailored aperture geometries configured for process vessels and bed distribution.
Water & Wastewater Treatment
Media retention in ion exchange resin columns, rapid sand filters, and carbon bed contactors.
Chemical & Petrochemical
Corrosion-resistant distribution and collection in acid tanks, reactor bottoms, and catalyst beds.
Power & Thermal Processing
High-temperature condensate polishing, boiler feedwater purification, and cooling tower loops.
Filter nozzle engineering specifications
Review slot aperture tolerances, flow metrics, alloy grades, and vessel underdrain compatibility for industrial water treatment and process vessels.
Two-point contact prevents particle wedging and allows rapid backwashing without blind spots.
Wedge profile wire is fully fusion-welded to support rods at every single junction for high burst resistance.
Standard units withstand collapse differentials exceeding 10 bar (145 psi) without slot distortion.
Electro-chemical pickling removes free iron and restores chromium oxide passivation for maximum longevity.

Need custom slot openings or non-standard vessel threading?
Our engineering team builds custom filter nozzles, header lateral systems, and media retainers machined precisely to your vessel drawing specifications.
Filter Nozzle Operating Environments
Engineered for high mechanical rigidity and uniform hydrodynamic distribution across demanding water filtration, demineralization, and chemical processing media beds.
Water Treatment & Sand Filter Underdrains
Engineered for municipal and industrial gravity/pressure sand filters, granular media vessels, and dual-media filtration beds.
Uniform distribution across entire bed surfaces prevents dead zones, channeling, and backwash media loss.
Resistant to abrasive sand particle scouring and cyclic hydraulic backwash shock loads.
Ion-Exchange & Softening Resin Columns
Precision slot tolerances down to 0.10 mm ensuring complete retention of fine cation/anion exchange resin beads under high velocity.
Continuous non-clogging wedge wire profile eliminates resin migration into downstream pure water circuits.
Passivated alloys withstand aggressive acid (HCl/H2SO4) and caustic (NaOH) regeneration chemical cycles.
Activated Carbon & Catalyst Retention
Robust double-head and long-stem nozzle assemblies for high-temperature chemical reactors, carbon adsorption, and gas scrubbing columns.
Robust welded structural integrity sustains high differential pressure during intense backflush sequences.
Custom threaded, flanged, or quick-release mounting stems engineered for rapid turnaround during plant shutdowns.
