Air Showers

Cleanroom Air Showers

Entry Decontamination Systems for Particle Control & Compliance

Cleanroom air showers are essential in maintaining contamination control in regulated environments. These enclosed chambers use high-velocity, HEPA-filtered air to remove particulates from personnel and equipment before they enter or exit a cleanroom.

Air showers support compliance with ISO 14644, GMP, and USP-797/800 guidelines, making them critical for pharmaceutical, semiconductor, medical device, and aerospace applications.

Their interlocking doors and automatic cycling regulate traffic flow, create an airlock barrier, and help maintain pressure differentials between zones — all while reinforcing protocol adherence among staff.

  1. Removes surface contaminants from people and carts using high-velocity air (up to 8,000 FPM)

  2. Maintains pressure control between classified areas

  3. Prevents entry of airborne contaminants and particles

  4. Offers visual reassurance of quality control to staff and visitors

  5. Reduces gowning room burden by intercepting contamination at the point of entry

🔧 Cleanroom Air Shower Technical Specifications

Function & Operation
Cleanroom air showers are designed to remove surface contamination from personnel or equipment before entry into a controlled environment. The air shower is automatically actuated upon entry, releasing a high-velocity bath of clean, HEPA-filtered air from the side walls and ceiling.

  • After a timed decontamination cycle, the system shuts off automatically and unlocks the exit door

  • Air is recirculated within the unit to maintain containment and reduce particle migration

  • Available in two standard configurations:

    • Model S: Straight-through design (standard)

    • Model L: Right-angle entry/exit design

  • Parts Pass-Through Air Showers for equipment decontamination are also available
