Laminar Air Flow

Laminar Air Flow - Air flow in which the entire mass of air within a designated space move with uniform velocity in a single direction along parallel flow lines with a minimum of mixing.

Air Flow Products provide you with the ultimate in localized, particulate-free, sterile environment and clean air workstations. Work stations and hoods can be located exactly where you need them, even in relatively inaccessible areas.

Bellco has outfitted safety cabinets and clean air systems to all sizes of lab facilities - from single units to entire buildings. Let our experts help you in choosing the clean air system which best fits your needs and budget.

Introduction to Laminar Flow Cabinets...
In the 1960's, due to the increased need for clean air in industry, laminar flow cabinets (also known as clean benches) were first developed to provide product protection for small-scale experimental procedures. Today they are ubiquitous in the laboratory.

A laminar flow cabinet provides a controlled environment (Class 10 or Class 100) in which levels of particulates, microbes, and contamination of all kinds are regulated and kept to a minimum by constant air filtration with industrial-grade filters.

How Does a Laminar Flow Cabinet Work?
A laminar flow cabinet creates a particle-free working environment by taking air through a filtration system and exhausting it across a work surface in a laminar or unidirectional air stream. Commonly, the filtration system compromises of a pre-filter and a HEPA filter. Because the air within the cabinet does not contain any airborne particles, it is also sterile. The laminar flow cabinet is usually enclosed on the sides and kept under constant positive pressure in order to prevent the infiltration of contaminated room air.

What laminar flow is used for: the most common application of the laminar flow cabinet is using it to provide an individual clean air environment for small items not requiring a full-size cleanroom. In the laboratory, individual laminar flow cabinets are commonly used for specialized work such as tissue culture to eliminate airborne contamination would otherwise interfere with work processes.
