CEFIL’AIR® Inflatable Seals

Pneumatic seals are the most straightforward, safest, and most efficient way of sealing parts that move in relation to one another and must be connected and disconnected. CEFIL’AIR® pneumatically expanded and retracted seals have a patented design that uses advanced elastomers and modern manufacturing techniques to fulfill the needs of a wide range of applications.

BIO-GUARDIAN® SEALS: The BIO-GUARDIAN® sealing solution restricts bacterial and microbial growth on equipment and materials, making it essential in the medical, pharmaceutical, and food industries. To meet the needs of demanding hygienic applications, the BIO-GUARDIAN® solution can be used in CEFIL’AIR® inflatable seals.

Features and Benefits

  • No seal stress while opening and closing phases
  • Expand and retract with the movement of fluids (pneumatic or hydraulic)
  • Highly flexible design: Available in a large selection of shapes and sizes
  • Large material selection: Silicone, EPDM, SBR, FKM, and HNBR, which provide greatly resistant mechanical and physical properties to guarantee a long lifetime and different operating cycles
  • RFID chips can be included for traceability and reliability
  • BIO-GUARDIAN® elastomers prevent the development of bacteria and biofilm formation
  • Laser marking for complete traceability
  • Can be used for moving, handling, holding, or clamping, particularly fragile, large, or complex objects

Product Applications

  • Movable cofferdam bulkheads
  • Leak-tight panels (naval, aerospace industry)
  • Storage and transport containers
  • Nuclear vessels (equipment or personnel chambers)
  • Clean rooms
  • Isothermal chambers
  • Phonic isolation
  • Centrifugal filters (access doors and drainage hoppers)
  • Sliding or quick-locking doors (autoclaves, sterilizers)
  • Aircraft access doors
  • Cockpit canopies
  • Cofferdams
  • Portholes
  • Pneumatic conveyors (bagging hoppers, valve gates)
