Vertical Laminar Flow Cabinets

For ultraclean working conditions

Vertical Laminar Flow Cabinets

Vertical laminar flow (VLF) cabinets from Contained Air Solutions are designed to provide the highest levels of air cleanliness within working zone.

Product details

We offer a range of vertical laminar flow products that are custom designed and manufactured to suit your exact requirements in accordance with EU GMP Grade A. Vertical laminar flow products provide ultraclean working conditions for medical, general laboratory and the manufacture of sensitive electronic devices.

Products include:

  • Horizontal laminar flow units
  • Vertical laminar flow units
  • Laminar flow benches and hoods
  • Laminar flow cabinets and booths

All vertical laminar flow products are designed to provide product protection by creating a particle-free working environment. This is achieved by passing air through an HEPA filter, which then provides laminar air flow across the main working area.

The vertical range of laminar flow cabinets utilise air taken from the laboratory, which is drawn inwards at high level and passes through a high efficiency pre-filter trapping larger particles.  The air is then passed through a HEPA filter. The filtered air is discharged over the work area in a unidirectional stream, providing a sterile working environment.
