IMPORTANT DESIGN PARAMETERS OF THE

CLEAN AIR EQUIPMENTS.


3/19

AIR SHOWER

It gives shower of sterile air with high velocity airjets, which helps to remove suspended particles,

bacterias on the clothing of personnel or the

material being taken inside the clean room

PRINCIPLE OF OPERATION :-


4/19

Air shower is installed at entry of

i) Clean rooms

ii) Operation theaters

iii) Calibration laboratoryiv) Electronic industries

v) Food processing

vi) Paint Shopvii) Germs & jewelry for recovering of gold

Application areas for Air Shower


5/19

It sucks the surrounding air & blows through

special designed rectangular nozzle at a veryhigh speed ( 2400FPM to 3600FPM) which

forms invisible curtain between the controlled

and uncontrolled environment.

AIR CURTAINS



6/19

It is fitted or suspended at top of the doors

i) Pharmaceutical

ii) Operation theatersiii) Food Processing,

iv) Dairy

v) Sweet mart & Honey collection centers

vi) Cold storages as a thermal barrier

vii) Show rooms & Offices

Application areas of Air Curtains


7/19

LAMINAR FLOW WORK STATION

HORIZONTAL


It sucks the room air through pre-filter anddelivers into work area through HEPA filter at

laminar air flow. Laminar air flow is horizontal.


8/19

LAMINAR FLOW WORK STATION

VERTICAL


It sucks the room air through pre-filter anddelivers into work area through HEPA filter at

laminar air flow. Laminar air flow is vertical.


9/19

i) Laboratories- R& D Biotechnology, Pathology

labs

ii) Institutes- Agriculture, Pharma, Biotechnologyiii)Hospitals- Pathology lab, Blood bank

iv)Industries- Electronics, Food processing,

Calibration, Watch mfg & repairing,Pharmaceutical, Bearing assly

v) Agriculture- Tissue culture

Application areas of LAF :-


10/19

FILTERATION MODULES

It re-circulates the room air through pre-filter &

fine filter so as to achieve the defined no of air

changes per hour. It helps to maintain the air bornecontamination level of room as per the clean room

cleanliness class. All the airborne contaminants gets

trapped in the HEPA filter so it needs to be

re laced after eriod of time.



11/19

i) Laboratories- R& D Biotechnology, Pathology

labs

ii) Institutes- Pharma, Biotechnology, Agricultural

iii)Hospitals- Operation theaters & ICU

iv)Industries- Electronics, Food processing,

Calibration, Watch mfg & repairing,Pharmaceutical, Bearing assembly

v) Agriculture- Tissue culture

Application areas of FM :-


12/19

ELECTROSTATIC

AIR PRECIPITATION UINT

It consists of pre-filter and electrostatic air

precipitator unit, in which fine dust particles up to

0.1 micron are gets collected on stack plates which

are connected high DC voltage.



13/19

Main advantage of this ESP unit is that it doesn't

require separate blower unit if installed in series

with the existing AHU system.

Stack assembly can be cleaned & reused again.

Hence power consumption & operational cost is

very low compare to HEPA filtration units.

Only drawback of this ESP unit is low filtration

efficiency as compare to HEPA filtration units.



14/19

Application areas of ESP :-

i) It is always recommended to use in series

with existing Air Handling Unit to reduce theburden on terminal HEPA filters & extend the

life .

ii) Self air circulating ESP units are suitable tomaintain air borne contaminant level in the

Telephone exchange, Server Rooms &

Broadcasting, which enhances the life ofelectronics being used.

iii)Precision machine shops, calibration labs,

quality control depts & banks.

FUME HOODS


15/19

FUME HOODS

Fume hood is confined work chamber and designedto collect all fumes generated on worktop during

the process and exhaust directly to the environment

through filtration system.Application areas

-Research laboratories

-Pharma

-Chemical industries


16/19

STERI AIR

STERI AIR is a small & compact filtration

unit with pre-filter, HEPA filter , Activated

Carbon Filter and Negative ionizer.


17/19

Longevity is suitable for,

-Small Offices,

-Bars & Restaurant to minimize the cigarettesmoke,

-Server Rooms,

-Patients having asthma, allergy, headache &fatigue .


18/19

GARMENT CABINETS

Garment cabinet consists of pre-filter, HEPA filter

Blower assembly & UV light. This provides sterile

environment for the sterile Garment, curb growth

of bacteria .


19/19

These Clean Air Equipments are designed forhazardous area Zone 1, Gr IIA/ IIB application

like,

-Pertochemical industries,

-Pharma industries where highly inflammable

chemicals are used-Satellite launching station,

-Chemical industries ,ammunition industries
