REVERSE LAMINAR AIR FLOW

PS AIR TECH offer easy solutions to control your dust and vapor in the form of RLAF. Our equipment is designed to protect workers from breathing unsafe levels of particulates during material handling operations.

Air flows from the booth ceiling, down across the operator’s head, and into a grille below the operator’s waist level, thereby drawing particulates away from the operator’s breathing zone. We designs both standard and customized downflow booth for clean room application. The containment booths are economical and offer unmatched usages and specifications.

Salient Features

  • Powder handling or tipping requirements
  • Electrical wiring to client standards
  • Physical Barrier by antistatic PVC curtains
  • Provide Operator Exposure Levels (OEL's) ≤100 micrograms/meter3 over an 8 hour Time Weighted Average (TWA).
  • Modular, easy-to-clean rigid design with minimal joints.
  • Single, Two-Stage or Three-Stage HEPA/ULPA filtration can be accom
  • Total exhaust airflow.
  • Corrosion Resistant interior and exteriors
  • Energy Efficient
  • Sturdy Construction
