7 Essentials PBSC Build into Our Inflatable Seal Doors

Seal integrity under pressure: inflatable seals rated for severe differentials

Our inflatable seals expand under compressed air to create a full perimeter barrier.

  • Built to perform at up to 2000 Pa (8″ w.g.) differential pressure.
  • Offered with silicone or EPDM seals to suit environmental and chemical resistance requirements.

Real-time monitoring & control: PLC logging, alarms and data integrity

Seal and supply pressure are continuously monitored so operators can always trust the seal.

Standalone PLC systems control, record and alarm, giving facilities data integrity and support for compliance.

Flush, obstruction-free threshold design for cleanability and safe trolley access

Our doors are engineered to sit flush to the floor, removing thresholds that cause contamination and trolley hazards.

  • Smooth transitions keep facilities efficient and safe.
  • No fixings in the flush threshold plate and pre-grouted thresholds to ensure there is no cavity under the threshold plate.

Flexible construction & materials: engineered for environment and risk profile

Door leaves are manufactured in stainless steel (304/316L), powder-coated steel, aluminium or phenolic resin.

  • Options for single or double seals depending on risk profile.
  • Unique cast 316 stainless-steel hinge assemblies, precision engineered in-house.
  • Lead shielding options.

Fail-safe protection: continued control in power loss and manual overrides

We build in options such as:

  • UPS to PLCs for continued control in power failure
  • Compressed air supply upgrades for power loss events
  • Pneumatic override buttons for safe manual release
  • Sampling ports for environmental monitoring

Vision & operator awareness: glazed panels, indicators and operator controls

Flush glazed vision panels are available in toughened or laminated glass.

  • Optional covers for privacy or security.
  • LED indicators and custom button sets keep operators informed.

Customisation & scalability: wall integrations, interlocks and large-format doors

Frames are engineered for multiple wall types, with options for concealed fixings.

  • Interlock systems to integrate into facility flows.
  • Hydraulic or automatic closers for efficiency.
  • Large-scale designs available, up to ~4 m high and 2.5 m wide.

Why it matters: doors as the barrier that protect people, processes and compliance

In containment and cleanroom environments, the door is the barrier. PBSC doors are engineered not only to meet compliance but also to deliver lasting reliability under real-world conditions. Talk to us about how the HC-ISD Inflatable Seal Door can be tailored to your facility.
