LAMINAR AIR FLOW CABINETS (LAF)

Laminar Flow Cabinets create particle-free working environments by projecting air through a filtration system and exhausting it across a work surface in a laminar or uni-directional air stream. They provide an excellent clean air environment for a number of laboratory requirements.

Uses

Laminar Flow Cabinets are suitable in the following sectors.

1. Pharmaceutical industries

2. Hospitals

3. Diagnostic & Pathological labs

4. Bio-chemical Research labs

5. Scientific Research & Development Institutes etc.

How They Work

The process of laminar air flow can be described as airflow where an entire body of air flows with steady, uniform velocity.

Laminar Flow Cabinets work by the use of in-flow laminar air drawn through one or more HEPA filters, designed to create a particle-free working environment and provide product protection. Air is taken through a filtration system and then exhausted across the work surface as part of the laminar flows process.

Commonly, the filtration system comprises of a pre-filter and a HEPA filter. The Laminar Flow Cabinet is enclosed on the sides and constant positive air pressure is maintained to prevent the intrusion of contaminated room air.

Types of Laminar Flow Cabinets

Laminar Flow Cabinets can be produced as follows.

• Vertical Laminar Flow Cabinets

• Horizontal Laminar Flow Cabinets

Horizontal Laminar Flow Cabinets

Horizontal Laminar Flow Cabinets receive their name due to the direction of air flow which comes from above but then changes direction and is processed across the work in a horizontal direction. The constant flow of filtered air provides material and product protection.

Vertical Laminar Flow Cabinets

Vertical Laminar Flow Cabinets function equally well as horizontal Laminar Flow Cabinets with the laminar air directed vertically downwards onto the working area. The air can leave the working area via holes in the base. Vertical flow cabinets can provide greater operator protection.
