Clean Room Equipments

Pass box is one of the cleanroom systems, which is used to transfer materials from one side to other side through controlled environment in order to avoid airborne cross contamination. As the name states itself, the primary and only work of a pass box is to pass material from one side to other without raising contamination concern and if any particulate matter presents on the material surface, it swipes away during the operation. Interlocking door mechanism is the prime feature of a pass box, when door at one side is open the door at other side remains closed. It is popular with other names such as cleanroom pass through, clean transfer window and transfer hatch; in addition, it is widely used in Microbiology Laboratories in Food, Pharmaceutical, Chemical Industries and Hospital A pass box is designed in two different types; Static and Dynamic, it is the user specific requirement which decides the right design configuration

Air Showers

Air Showers are self-contained chambers installed strategically at entrances to cleanrooms and other controlled environments. They minimize particulate matter entering or exiting the clean space to mitigate the risk for cross-contamination.

How an Air Shower Works

1. Completely self-contained, pre-wired, fully equipped Air Shower/Tunnel systems help solve decontamination problems
2. Modular design lets you order a system to suit your cleanroom
3. HEPA filter/blower modules (rated 99.97% efficient @ 0.3-micron particles) wash personnel with Class 100 air to dislodge and remove particles
4. Solid-state microprocessor panel provides programmable control over access door operation
5. Interlocking doors minimize contamination, release automatically in the event of power failure
6. Fluorescent lighting is housed in the ceiling for minimal turbulence
7. Available in white epoxy-finished CR steel, stainless steel, or plastic laminate to meet various cleanroom requirements
8. Variety of sizes and door configurations
9. Economical to operate, easy to maintain
10. System options include HEPA-filtered ceiling, ionized grid, and safety glazing
11. These Air Showers and Tunnels offer an effective way to remove surface-deposited particles from personnel—before they get to the cleanroom.

A dynamic pass box is fitted between classified and non-classified areas. Material is passed through vertically HEPA filtered air.

Sampling/Dispensing Booth

Assembled dispensing booth, also called sampling or weighing booth, down flow booth or powder containment booth, is dedicated purification equipment for sampling, weighing and analysis. It can contain powders and particles within work area and prevent operator from inhaling them

• Negative pressure design contains powder and particles inside booth, not overflowing booth
• Stainless steel construction make booth clean and hygienic
• Assembly design makes it possible to enter completed clean room
• Complete with user’s manual, assembly drawing, quality certificate, test report, etc.
• One set of pre-filter and medium efficiency filters as spare parts

Technical specification

• Sound level minimum 65db on scale
• Power supply single phase 220v 50 HZ

Static pass box on the other hand is fitted only between two clean room areas and has no air supply or extract. It is also known as passive pass box and equipped with UV Light

In the process of material transfer from unclassified area to classified area pass box used. Pass box is rectangular box with two or three doors. The doors are interlocked such a way that doors cannot be open at the same time, due to which pressure losses and bacterial contamination doesn’t take place throughout the material transferring process. The prevention of simultaneous access of doors has been achieved by our Pass Boxcontroller by ensuring that when one door for a Pass box is open then other doors closed
