For decades, PBSC air showers have supported critical cleanroom environments, keeping people and processes safe. Our original designs established benchmarks for personnel decontamination, offering reliable performance for the cleanrooms of that era. Twenty five years on, our commitment to innovation and quality continues, delivering advanced solutions for the evolving needs of cleanrooms and regulated sectors.

Construction & doors: robust materials and installation flexibility

  • Stainless steel or powder coated steel construction
  • Interlocked toughened glass personnel doors
  • Maximum clear opening with flush frame (straight through design)
  • No crane required for installation – fits through a standard doorway

Airflow & decontamination: high flow nozzles and return air integration

  • High Flow version: 30 adjustable stainless steel nozzles (15 per side)
  • Velocity: 30-32 m/s (approx. 98-105 ft/s), providing 3,670-3,900 m³/hr (approx. 2,160-2,295 CFM)
