Vertical Laminar Air Flow
Vertical Flow Laminar Flow Systems.
"Cleanair" Series 'V'.
Tech. Know-How C.E.R.E.R.I. (Pilant) Thru N.R.D.C. (Govt. Of India).
Variants :- Wooden/MS Powder- Coded/ Stainless Steel.
The basic elements of Clean Air System are Pre-filter, Heavy Duty Blower Assembly, HEPA (High Efficiency Particular Air) Filter (Absolute Filter) and the work area. The "CLEANAIR" Laminar Flow Benches which are indispensible in all precision work laboratories utilises the proven Laminar Air Flow Principles U.S. Fedral Standard 209 (Class 100), latest version.
Fresh Air is drawn through the Pre-Filter and passed through maximum efficiency Absolute HEPA Filter. Clean air moves, Vertically down-wards in Laminar Flow Bench across the work area at a velocity of approx 90 + 20 ft. per minute. This velocity of Clean air makes it virtually impossible for the operator, positioned in front of the work area, to contaminate it. All contamination generated by him such as hair, salt, skin flakes, etc. is blown away by the Clean Air Flow, nor allows the atmospheric pontamination to enter the work area.
HEPA Filter is the heart of the CLEAN AIR Flow System. It removes all particles from the air, which are larger then 0.3 micron size. We use HEPA Filters fabricated out of a continuous sheet of fire-retardant, water repellant, micro-fibre-glass filteration media tested for DOP Penetration Tests. While we ensure that these specifications are fully met by the HEPA Filter. This filteration area is about 50 times the face area of the filter, which result in Laminar Flow of Air.
The DOP Test:
The most accurate and demanding test of any filter used today for precision research work was developed by the U.S. Army Chemical Corps. It incorporates a DOP Smoke generator and a forward Light Spectrophotometer. The test determines the filter efficiency by measuring the percentage of 0.3 micron smoke particles.
Standard availability in 2/2", 3/2", 4/2", 6/2" 8/2" and any other size.
