Cleanroom Equipment

Cleanroom equipment covers the peripheral components required for a complete clean environment, including Air Showers, Pass Boxes (including VHP sterilization type), FFU Fan Filter Units for modular cleanrooms, Clean Benches, and Clean Booths for localized clean zones. Comprehensive cleanliness control requires integrating high-velocity airflow (≥25 m/s), personnel decontamination, material transfer isolation, and localized workspace cleanliness — purchasing filters alone cannot achieve systematic results.

Main equipment categories: Air Showers use high-velocity clean airflow (≥25 m/s) to flush particles adhering to personnel clothing; Pass Boxes are classified as standard, self-cleaning, or inflatable-seal types, selected based on material transfer risk level; FFU Modular Cleanrooms use FFU arrays with support structures, wall panels, and doors to build scalable clean spaces; Clean Benches provide localized clean work zones in horizontal-flow or vertical-flow configurations.

Typical applications: semiconductor cleanroom entry control, biotech R&D GMP zones, hospital pharmacy compounding rooms, food aseptic packaging, and PCB assembly clean areas.

Other peripheral equipment includes: HEPA diffuser boxes (including a liquid-seal type) as ceiling terminal filtration on central HVAC systems; FFU central control systems that manage zoned start/stop and speed for large numbers of FFUs; pressure relief dampers that open automatically when pressure exceeds the set point to hold room pressure differentials; air filter holding frames that locate and seal HEPA / ULPA filters in ducts or ceilings; nitrogen and dry cabinets that store moisture- and oxidation-sensitive electronic parts and wafers; stainless steel fume hoods that exhaust hazardous gases from lab work; and automatic hand wash and dryer units at gowning-room entrances that wash and dry hands without contact.
