Quick lock system


  • Single piece head assembly manufactured by engineering thermoplastics provides high strength and superior chemical resistance
  • Improved head seal captured in the head gives better sealing, minimizing leakage probability
  • Integrally formed locking  grooves provide better locking strength
  • Mirror finish ID for easy and quick loading and unloading of membranes
  • Exteriors coated with high gloss polyurethane paint for UV resistance
  • Head seal area is formed by mandrel surface; hence more accurate
  • Compact design for use in compact and low energy water treatment units
  • Quick lock head retention system for quick onsite maintenance

Unique benefits

The 40L30N membrane housing has 5 unique benefits

  • Compact design for use in compact and low-energy water treatment units
  • Quick locking mechanism: The user-friendly quick lock system eliminates the need for special removal tools and allows quick access to the membranes

  • Single-piece head assembly made of high-grade thermoplastics for high strength and superior chemical resistance
  • Improved head sealing: Integration into the end plug provides better sealing and avoids head seal roll
  • Integrally wound locking groove: enhanced end-margin strength for better performance
