Inflatable Seals

Inflatable Seals

Inflatable seals are the perfect solution for difficult sealing conditions. They are particularly well suited for use with:

  • Horizontal or vertical sliding doors.
  • Processing equipment where rapid sealing and unsealing is required.
  • Hinged doors with flush thresholds for easy personnel or equipment access
  • Large fabricated doors or other closures where it is impractical to machine the sealing surfaces to accommodate conventional seals and gaskets.

Doors and other closures can be positively sealed with inflatable seals. Seals are typically inflated with air (or other fluid) using a pressure regulated supply system. When pressurized, the inflatable seal conforms to uneven surfaces and provides an efficient, reliable barrier to dust, moisture, contaminants, and/or pressures. Inflatable seal operating pressures are usually in the range of 10 to 35 PSI (1–3 bar) but some styles can be designed to operate at lower or higher pressures depending on the need. Expansion capabilities (i.e. the ability to close a gap) vary by profile. Large gaps may be accommodated but it should be noted that as the gap increases, the pressure required to seal against a given pressure differential increases, thereby decreasing the seal’s flex life.
