Laminar Air Flow Cabinet Horizontal Waiometra

Password protection, UV Tube & Front Door Interlocking, UV Tube life meter, HEPA Filter life meter & alarm


Waiometra 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 unidirection velocity flowing in parallel lines, which is free from macroscopic fluctuations. The horizontal laminar air flow units direct 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.

Display of life used & life remaining of HEPA filter and UV tube
HEPA filter alarm after HEPA filter life is over and guideline for further action through LCD controller
Audio Visual door unsafe alarm, if door is at incorrect operating height.
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.
Display of safe / unsafe position of door
