Laminar Air Flow Cabinet

LABTOP Laminar Air Flow Cabinet is a carefully enclosed bench designed to prevent contamination of semiconductor wafers, biological samples, or any particle sensitive device. The cabinet is made of mild steel or stainless steel. These Laminar Airflow units are used for applications such as tissue culture, media preparation, sterile handling, PCR sample preparation and many more.
LABTOP Laminar Flow Chamber exist in both horizontal and vertical configuration, these laminar air flows are widely used in pharmaceutical industries, hospitals, manufacturing facilities, blood banks and research centers.
Laminar Flow Cabinets may have a UV-C germicidal lamp to sterilize the cabinet and contents when not in use.

The instrument is provided with a pressure manometer which indicates the air pressure. A fully automatic dedicated microprocessor helps in monitoring all the functions of the Laminar Air flow cabinet. The advanced microprocessor monitors the air flow in real time to prevent sample. A high quality membrane keypad permits control settings and access.

Construction
All Laminar Flow Clean Air cabinets are basically constructed with an outer body of mild steel duly powder coated. The inner work table is made of stainless steel. The front of the cabinet is provided with motorised glass door which is very easy to use.

The micro controller controls the ON/OFF for blower operation, UV germicidal light, fluorescent light, and mains. A high quality air velocity sensor helps in sensing the actual air flow in FPM.
This microprocessor warns for any deviations in the air velocity from normal velocities.

Blower Motor Assembly
Dynamically balanced, direct drive highly efficient centrifugal blower to provide adequate air flow over the entire surface of HEPA filter. These are directly coupled to an inbuilt motor and operate with minimum noise level i.e. lower than 65 db on scale and vibration less than 2.5 um.

Air Flow and Filtratlon
Laminar air Flow principle involves double filtration of air, Atmospheric air is drawn through pre filter and is made to pass through highly effective HEPA (High Efficiency Particulate Air) filters having efficiency rating as high as 99.99% with cold DOP and 99.97% with hot DOP thus retaining all airborne particles of size 0.3 micron and larger.
