SALIENT FEATURES :
Low Noise And Vibration Levels
Conforms to US Federal Standard 209 B
Calibration And Protocol Documentation
PRODUCT DETAILS :
The cabinet are fabricated out of thick board duly sun mica clad interior surface are epoxy painted for its longer life. The work table is made of thick board which is S.S. 316Qlty. clad at top. Side panels are made out of thick transparent plexi glass duly framed. The unit is fitted with pre filter & HEPA filter. Air is drawn through pre filter & is made to pass through highly effective HEPA (High Efficiency Particulate Air) filter having efficiency rating as high as 99.99% with cold DOP & 99.97% with hot DOP, thus retaining all - air borne particles of size 0.3 micron & larger. Using a dynamic machine the blower & motor assembly is statically & dynamically balanced ISI Marked Motor of 1/5 H.P. capacity operates with minimum noise level. The working area is illuminated by fluorescent lighting fitted to the unit. Height of the working table provides comfortable ‘sit down’ working position for the operator. To Work on 220/.230 volts. A.C. Supply. Supplied complete with S.S. table top, HEPA filters pre filter & fluorescent illuminations & U.V. Light.
PRODUCT OVERVIEW :
Our vertical laminar air flows 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. Our laminar air flow bench is fast gaining popularity in other fields, such as pharmaceutical production, electronic industries and various other manufacturing applications.
PROCESS EXPLANATION – LAMINAR AIR FLOW TECHNOLOGY :
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 uni directional velocity flowing in parallel lines, which is free from macroscopic fluctuations.
The vertical laminar air flow units directs the air in mono direction which is towards the specimen and away from the user, giving ultimate protection to the user who is susceptible to contamination induced by diffusion of contaminated air, generated while handling hazardous pathogens, bacteria, viruses etc.
Laminar Air Flow
All the vertical laminar air flow benches are classified into three broad categories as per US Federal Standards 209 B Ans 209 E (latest revision on 11.09.92). As per this standard the particle count in the existing air around the work table is taken into account.
Vertical/Horizontal Laminar air Flow Class 100
These laminar air flow units are those where the particle count of size 0.5 micron and larger is less than one hundred particle/ cubic feet, in the area of work.
Vertical/Horizontal Laminar Air Flow Class 10,000
These laminar air flow units are those where the particle count of size 0.5 micron and larger, is less than ten thousand particle per cubic feet or sixty particle per cubic feet of dimension larger than five micron and bigger size in the area of work.
Vertical/Horizontal Laminar Air Flow Class 1,00,000
These laminar air flow units are those, where the particle count of size 0.5 micron and larger is less than one lac particle per cubic feet or seven hundred particles per cubic feet of dimensions five micron or larger. In the area of work.
Basic Construction :
Our Vertical laminar air flow bench are designed to conform to the united states federal standard 209B/BS5295 and meets the class 100 conditions. Our units are fabricated of industrial grade wooden boards covered with mica sheets. The inner portion of all our laminar air flows are painted with epoxy paint coating for extra long life. The working table is made of heavy gauge stainless steel sheet of grade ss-316. The side panels made out of heavy plexi glass sheets are mounted on anodized aluminum frames. The whole unit is supplied with differential manometer to gauge the pressure drop in the unit while operation, beside the gas cock, power socket etc.
Filter Assembly :
All our laminar air flows are fitted with fully washable synthetic pre-filter units and secondary high efficiency perfect air filters made of mini pleated non woven fabric. The efficiency of our filters have a rating better than 99.99% at DOP (cold) and 99.97% at DOP (Hot). Our units have the capacity to hold all suspended particles of size 0.3 micron.
Motor And Blower Assembly :
All our Vertical laminar air flow units are provided with perfectly balanced (Static as well as dynamic) motor and blower motors bearing ISI mark. The rating of the assembly is 1/5 HP. Our high efficiency pumps which have lifelong lubricated bearings ensure a trouble free operation for a long time.
All the units are provided with adequate illumination at the work table by means of fluorescent lights panel concealed at the upper portion of the unit. The illumination at the work table is approx 800 lux.
Ultra Violet Light :
Optimal wattage ultra violet light is incorporated in the illumination panel of our laminar air flow to take care of the sterilization of the existing air present in the enclosure, thus ensuring the high standard of cleanliness in our equipment before the commencement of actual working.
NOISE LEVEL :
Our laminar air flow bench are designed to ensure that the work enclosure have minimum possible vibration levels and noise level is also contained below 55 db.
