Horizontal Laminar Air Flow (HLAF)

Horizontal Laminar Air Flow (HLAF) as part of cleanrooms and HVAC with its horizontal unidirectional airflows, has a role to play in creating and sustaining contamination-sensitive zones. By delivering HEPA-filtered air in a steady horizontal stream across work surfaces, it pushes away airborne particles from critical zones either toward the back of the unit or to the exhaust area.

HLAF systems help maintain ultra-clean workspaces ideal for precision tasks by minimising turbulence and ensuring a smooth, uniform flow.

They are the best fit for applications where product sterility is a must. They have proven to be reliable, and with ergonomic design and high-efficiency particle control, they form an essential part for industries such as pharmaceuticals, microelectronics, research laboratories, and healthcare. HLAF systems are thus a highly trusted solution to meet strict cleanroom standards that ensure process and product integrity.

Ambient air flowing horizontally across the workspace is first drawn through a pre-filter and then pushed through a high-efficiency filter by a built-in fan. The clean air thus produced moves horizontally from the back of the unit toward the operator. Moving very fast, the filtered air sweeps away particles and prevents contaminating matter from reaching critical work areas. The design of HLAF systems ensures the protection of products in the cleanroom by creating a particle-free zone. It is thus widely used in situations where contamination control is critical.

Working Principle of Horizontal Laminar Air Flow

A Horizontal Laminar Air Flow (HLAF) unit is a specialised clean air system that forms part of cleanrooms. It delivers steady, unidirectional air flows originating from HEPA or ULPA filters.  Ambient air flowing horizontally across the workspace is first drawn through a pre-filter and then pushed through a high-efficiency filter by a built-in fan. 

The clean air thus produced moves horizontally from the back of the unit toward the operator. Moving very fast, the filtered air sweeps away particles and prevents contaminating matter from reaching critical work areas.  The design of HLAF systems ensures the protection of products in the cleanroom by creating a particle-free zone. It is thus widely used in situations where contamination control is critical.
