High Flow Filter Cartridges

Choose High Flow Filter Cartridges when:

• You want to upgrade an existing system to higher throughput without adding more housings.
• You are designing a containerized or skid-mounted unit where space is limited.
• Labor or downtime for filter change-out is expensive and must be minimized.
• Your plant is targeting lower total cost of ownership through reduced filter usage and energy savings (lower ΔP).

Yes. Our cartridges are engineered to be fully compatible replacements for:

• Pall Ultipleat
• Pall Marksman
• 3M 740B / 7000 series
• Pentair Aqualine
  We match the dimensions, end-cap design, sealing, and flow direction for easy installation.

When specifying High Flow Filter Cartridges, start from system hydraulics:

1. Total system flow (m³/h or GPM)
   • Determine flow per housing and per cartridge. High-flow elements commonly handle
     up to ~500 GPM (≈113 m³/h) per 60″ element in ideal conditions,
     but are typically sized with a safety factor for longer life.
2. Allowable pressure drop (ΔP)
   • Consider maximum ΔP at clean start-up and at change-out.
   • High Flow Filter Cartridges usually run at much lower initial ΔP than equivalent bag or standard cartridges due to greater surface area.
3. Micron rating & filtrate quality
   • Typical range: 1–5 µm for RO pre-treatment,
     10–20 µm for general process water,
     up to 50–100 µm for coarse protection or pre-filters.
4. Configuration: Inside-out vs. outside-in flow
   • Inside-out flow designs trap dirt on the inner layer, keeping the outer surface cleaner and simplifying cartridge removal.
   • Outside-in flow maximizes surface area contact first and is widely used in replacements for 3M Cuno and similar designs.
   • Omela supplies both configurations to retrofit existing housings without modification.
5. Housing & connection
   • Match diameter (≈6–7.75″), length (20″/40″/60″), and
     end-cap style & O-ring material (EPDM, NBR, Viton, silicone)
     to the installed housings and fluid chemistry.

Common media options:

• PP (Polypropylene):
  • Best choice for general industrial and potable water, many chemicals, and RO pre-treatment.
  • Excellent compatibility with most neutral and mildly aggressive fluids; max temperature typically around 80–90 °C.
• PES (Polyethersulfone / membrane combos):
  • Used for high-purity applications (pharma utilities, electronics rinse water, beverage polishing).
  • Provides tighter microbial and fine-particle retention.
• Fiberglass / Glass fiber:
  • Suited to high-temperature or hydrocarbon service, condensate, and some petrochemical duties.
• Hybrid & carbon options:
  • For chlorine reduction, organics control, or specialty fluids, Omela can integrate carbon or layered structures based on project needs.

Selection tips:

• Map process fluid, temperature, and pH to media compatibility charts.
• For stringent SDI/turbidity targets prior to RO, combine a tighter micron rating (1–5 µm) with high-efficiency pleated PP or PES.
• For viscous or high-solid liquids, consider slightly coarser microns plus staged pre-filtration to protect the high-flow elements.

Key monitoring points:

1. Differential pressure trend (ΔP in/out)
   • Track ΔP from start-up to change-out; a gradual, predictable rise indicates stable loading.
   • Sudden spikes may indicate upstream upsets, plugging, or bypass.
2. Flow rate vs. setpoint
   • Ensure pumps are not pushed beyond cartridge design flow, which can cause media deformation or channeling.
3. Outlet turbidity / SDI / particle counts
   • Monitor filtrate quality; any deterioration before expected life suggests bypass, housing seal issues, or incorrect micron rating.
4. Visual inspection at change-out
   • Check for media damage, collapsed cores, end-cap cracking, or O-ring extrusion.
   • Uneven loading (clean zones vs heavily loaded bands) can signal poor flow distribution in the housing.
5. Service life benchmarking
   • Record hours of operation, processed volume, and average inlet quality.
   • Use this data to optimize micron rating, staging (coarse → fine), and change-out setpoints to maximize lifecycle economics.

We offer multiple media options depending on chemical and thermal requirements:

• PP (Polypropylene) – most common, broad chemical compatibility
• PES (Polyethersulfone) – high efficiency, low protein binding
• PTFE – for aggressive or high-temperature liquids
  O-ring options include EPDM, Silicone, Viton.
