3. Filter Pad

The prefilter or the primary filter that initially sucks the air and performs the first

stage filtering of air (impure particles of size 5 microns or higher typically get

trapped by a filter pad). In a placed on the top of the device (vertical laminar) or at

the bottom of the chamber (horizontal laminar).

4. Fan or Blower

sucks the pre-filtered air through the filter pad and transmits it towards the high-

efficiency particulate air filter.

5. HEPA Filter

High-efficiency particulate air filter is a special air filter present inside the chamber

that helps in the removal of all sorts of contamination particles including bacteria,

fungi, and dust particles to maintain a safe and sterile environment.

the pre-filtered air is made to pass through the HEPA filter, which acts as the

secondary or final filter. The particles that are even 0.3 microns in size can be

successfully eliminated

6. UV Lamp

is generally used to kill the germs and bacteria that are invisible to the naked eye.

The chamber must be thoroughly exposed to ultraviolet radiation before and after

use.

The UV lamp should be turned on at least 15 minutes before the operation.

7. Fluorescent Lamp Produces proper illumination and lightning inside the
