Model Item / SKU

3al3281-ft-230v

This model is part of the United States catalog.

Our 3AL3281-FT-230V model 3AL liquid ring system supports vacuum to 28.5 in. Hg and delivers airflow to 144 CFM . Designed as a complete, plug-and-play solution, the 3AL3281-FT-230V helps increase uptime and reduce water consumption with a full internal recirculation system and stainless-steel enclosure. All 3AL Series units feature an air-cooled design that removes the need for external cooling water systems. With an integrated water tank and a fully recirculating system, no freshwater connection is required after the tank is initially filled. The stainless-steel impeller, internally coated housing, and stainless-steel wash-down enclosure make this series well suited for food processing, medical, dental, and pharmaceutical sterilization environments. The 3AL’s compact design allows the system to be installed in tighter spaces.

3AL Highlights

  • Full Recirculation System: Internal water tank supplies and recirculates water through an integrated heat exchanger
  • Optimized Water Consumption: Built-in limiting valve restricts purge flow to just 0.06 GPM during operation, minimizing water use
  • Plug and Play: Complete, self-contained system solution ready to install and operate, suitable as a standalone unit or integrated into larger vacuum systems
  • Robust Design: Handles vapor carryoverand small particulate contamination that would damage dry-running vacuum technologies
  • Stainless Steel Components: Stainless steel impeller is standard in design, internally coated for corrosion protection, stainless steel enclosure suitable for wash-down applications
  • Low Noise, Compact Footprint: 65–72 dBA operation in a space-saving design, quiet enough for tight space installations in healthcare and laboratory environments
  • Low Maintenance: Mechanical seals are standard, seal kits available to extend service life with minimal scheduled maintenance
  • Air-Cooled System: Ideal for temperature-controlled environments, no external cooling water infrastructure required
  • Application Focus: Medical suction, dental suction, pharma sterilization, food marination, meat processing, and distilling
