Overview

Laminar flow benches are a critical component of any cleanroom facility. Liberty designs and manufactures to your specifications coupled with our decades of experience. Benches can be horizontal, vertical or cross flow configurations, whichever maximizes contamination protection for your application.

  • ¾ Novaply - laminated in high pressure plastic
  • 16 gauge stainless steel, 304, 316L also custom quoted
  • CRS, Cold Rolled Steel, 16 gauge painted

Installation

Liberty Laminar Flow Benches are self contained, there is no need to assemble if needed to base with cabinet, plug in and ready to use.

How do I decide if I need a vertical or horizontal flow hood?

Horizontal units are appropriate when the product and process at the work surface must come first in line with the clean air stream.

Vertical flow units are appropriate when the proves generates vapors, the work surface must be isolated from vibration or both processes and personnel must be protected from powders, solvents and or chemicals.

Vertical flow fume hoods are appropriate with exhaust systems (supplied by customer) and should be used whenever irritants or noxious chemicals will be used in a work area.
