LCD/LED display of Air Velocity, Alarm for Undershoot / Overshoot of Air Velocity


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 unidirectional 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 screen to provide information about all the functions of the Laminar Air flow Cabinet.
Programmable UV Light to allow specific exposure time from 0 to 60 minute with automatic shut-off features UV interlocking with front window i.e. closed automatically when front window is open.
Fully Automatic Microprocessor Controlled.
Automatically adjustment of motor speed to ensure safe airflow.
LCD/LED display of Air Velocity, Alarm for Undershoot / Overshoot of Air Velocity.
Password protection (Programmable) for authorised operation.
UV timer showing used time and balance available life in hours.
Total HEPA Filter timer showing used time and balance available life in hour.
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 for door.
Ergonomic Design.
Versatile Usage.
Energy Efficient Mechanism.
Low Noise and Vibration Levels.
Long Life and Low maintenance .
Guaranteed supply of spares for 10 years.
Conforms to ISO 14644.1 Class 3 or better cleanliness level.
Onsite installation and after sales service by company trained engineers.

Waiometra laminar air flow cabinets are ideally suited in all the applications requiring protection of biological specimens or products from the possible contamination during the process or test. Waiometra laminar air flow bench is popular in pharmaceutical production, electronic industries and various other manufacturing applications.

Construction Options
(i) Full body made of Mild Steel / G. I. Sheet duly powder coated (totally in white colour) with S. S. table top
(ii) Full body made of S. S. 304.

The 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 sliding up and down with a very light hand pressure as it is counterbalanced with another weight. 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.
