Laminar air Flow is localized clean air station to carry out various test under ISO Class 5 (ISO std. 14644-1) filtered air. Horizontal Laminar Air Flow is used when non toxic and nonflammable tests are carried out. Laminar Unit also consist of UV light, UV hour meter, Steripot as per requirement. Sometimes antistatic grill is provided to remove the static charge as per client requirement.

Vertical Laminar Air flow bench is used when air flow requirement is from vertical fashion. It is used when toxic or flammable tests are carried out in Laminar Air. Vertical air flow avoids direct throw of the air towards operator’s face. Shutter is provided to avoid the air throw to the operator face.

Reverse Laminar Air Flow(RLAF) is used to control the hazardous emissions of powder dust during powder dispensing/sampling processes without any risk to operator and products as well protecting the environment. The downdraught of HEPA filtered air prevents airborne dust caused by handling operation away from the operator breathing zone. Three levels of air filtration is carried out into the booth air stream. Primary filtration at 10 micron, Intermediate filtration at 5 micron and final filtration at 0.3 micron through Mini pleat HEPA filter. Exhaust through mini-pleat HEPA filter at top of the unit.

Vertical Laminar Air Flow unit draws air in through the top or side of the unit through pre-filter ,through a plenum and vertically down over the work surface and past the lap of the operator. It has the advantage of not passing air towards the face of the operator. It is used for work with low risk substances with protection of working material from environment. MS CRCA or SS 304 perforated grill or CG screen is provided at filter face as per requirement. It is used as OT Plenum also.

Fan Filter unit (FFU) is a leading edge FFU unit designed to provide filtered laminar air flow over a specific area. The unit integrates a high efficiency fan together with a HEPA/ ULPA filter. The FFU draws in contaminated air from top of the module and exhausts filtered clean air vertically class 100 to class 100000 clean rooms. (as per US Federal Standard 209 E or ISO-Class 5- ISO Standard 14644-1 ).

Mobile Laminar Air Flows are used for transportation of the sterile products inside the ISO(14644-1) Class 5, ( FED Std 209 E Class 100) particle free work area to ensure that the contamination free transportation is carried out. The working area is under positive pressure class 100 filtered area hence avoids contamination. Battery back up is provided to maintain air flow continuity during transportation. Side vinyl curtains or acrylic sheet is provided as per requirement.

Bio-safety cabinet is used to protect product, personnel and environment. Mostly it is used when risky microorganisms are handled. Most widely used Bio- Safety Cabinet are of class-II type A2and B2. Class-II A2 type Bio-Safety cabinet have partial exhaust i.e. 30% and Class-II-B2 cabinet have 100% exhaust. Type-II B2 cabinet is used when most toxic or radioactive substances are handled..

Positive Pressure Module is designed to maintain positive pressure inside work area. It is wall mounted type or Ceiling suspended type. It is of having capacities of 150 CFM to 1500 CFM. Larger modules are normally used in production area. The smaller units are used to reduce biological and non biological airborne particulate activity in microbiological laboratories and intensive care units..

Air showers are used at entrance of dust free premises. High velocity clean air bath is created inside air shower chamber to remove dust particles from human body ,clothes and material if carried out through the air shower. It is a barrier by door interlocking between internal & external environment to avoid the dust. It is used as recovery unit also in gold industry. Gold dust trapped in HEPA filter is recovered by burning the HEPA filter.

Air mist shower is a contamination control equipment for the respiratory protection from inhalation hazards to the operator during de-gowning process. When person removes his/her protective clothing he/she also removes primary personal protection (respirator ) . The mist air shower is used to reduce the possible deposition of the particulate in the operators breathing zone. Air mist shower also reduces contamination in de-gowning area. Air mist shower works by wetting the surface of operators gowning with fine mist causing the powder to stick the gowning surface instead of becoming airborne contamination.

Specially designed garment cabinet provides a wash of sterile filtered clean air through HEPA filters. The cabinet protects dust and other particulates on clean room garments or other material. It is kept in change room to store the garments. It is of vertical air flow type or horizontal air flow type depending upon the requirement. Sometimes heater is also provided to dry the wet garments to avoid sweating odor from the garments.

Personnel traffic is the most important factor which must be controlled. Pass boxes allows material to be transferred without actual personnel movement. Freudenberg Static pass boxes are used when material movement is inside the classified area’s. Pass boxes are provided with door interlocking system to avoid contamination. Inside pencil coving is provided to avoid dust deposition in the pass box working area.

Dynamic pass boxes are used to transfer the material through controlled environment without much personnel movement. It avoids cross contamination during transfer of the material. Pass boxes are available with some standard dimensions but it is manufactured as per customized requirement also. Filtered HEPA air is provided inside the pass box to avoid contamination. UV light and Florescent light is also provided in dynamic pass boxes.
