Laminar Flow Cabinets

Product Description

The Laminar Flow Cabinet’s airflow is controlled, once-through, and non-turbulent. This ensures operators, products, and processes are protected from dust and fumes. The filtered downflow of air means only clear air reaches the operator’s breathing zone, and particles generated by the processing activities are pushed away.

Hosokawa’s laminar flow booths are available in standard sizes up to 4m or can be custom-built to customer specifications. This allows for a broad range of containers to be handled either manually or automatically. They are available as fixed, portable, or as a standalone workstation.

The advanced technology we have access to means we can individually design each laminar flow hood to meet specific requirements. They can be supplied with integral fan/motor systems, with filling & weighing systems, or with manufacturing and processing equipment zoned according to area classifications.

Air is extracted at the back of the booth through a full rear plenum space and is designed to give a laminar pull of air to 0.5 m/sec across the open front face of the booth. This creates a non-turbulent airflow and pulls away any product emissions from the work area and operator.

Typical Applications of Laminar Flow Cabinets:

  • Charging and discharging
  • Filling and weighing
  • Inspection and dispensing
  • Vacuum transfer
  • Liquid and solvent pumping and dispensing

Rear plenum chamber with air control valves for guaranteed product integrity.
