USESONAR laminar air flow cabinets are conceptualized to provide a work area completely bathed in high efficiency perfect air which is free from any kind of particulate contamination or impurities. These units are ideally suited in all the applications requiring protection of biological specimens or products from the possible contamination during the process or test. SONAR laminar air flow bench is popular in pharmaceutical production, electronic industries and various other manufacturing applications.

• Password protection (Programmable) for authorised operation

• Initial self cleaning cycle with programmable time• Real time Clock• UV timer showing used time and balance available life

in hours• Total HEPA Filter timer showing used time and balance

available life in hours• HEPA filter alarm after HEPA filter life is over and

guideline for further action through LCD controller• UV light/Door/Fluorescent Light Inter Lock i.e. UV

switches ON only when door is closed, and automatically switches OFF fluorescent lights.

• If UV light is ON & the operator tries to open the door, it raises audio visual alarm.

PRINCIPLEThe Laminar Air Flow Cabinets are based on the principle to provide a work area completely bathed in a high efficiency perfect air, which is free from any kind of particulate contamination or impurities.HORIZONTAL Laminar air flow are clean benches which have their own supply of highly purified air in which the total air present in the enclosure moves in a unit directional velocity flowing in parallel lines, which is free from macroscopic fluctuations. The horizontal laminar air flow units directs the air in mono direction which is away from the specimen and towards the user, giving ultimate protection to the product, which is susceptible to contamination induced by diffusion of contaminated air carrying air transported contaminants from the outside environment.

CONSTRUCTIONThe Work Table is made of S.S. 304. Side panels and front door are made of thick plexiglass of special grade to resist the UV effect. Front door has a unique feature of double fold system. It can be half/full open during working. The entire unit rests on four castor wheels. The unit is completely modular & can be disassembled/assembled by the user within 10 minutes.
