A clean room is a controlled environment where pollutants like dust, airborne microbes, and aerosol particles are filtered out in order to provide the cleanest area possible. Most cleanrooms are used for manufacturing products such as electronics, pharmaceutical products, and medical equipment. A cleanroom can be classified into different levels of contamination depending on the amount of particles allowed in the space, per cubic meter. Cleanrooms also control variables like temperature, air flow, and humidity.

HOW DOES IT WORK?

Essentially, cleanrooms work to remove pollutants, particles, and contaminants from outside ambient air. Outside air is first circulated to a filter system. The filters (either HEPA or ULPA) then clean and decontaminate this outside air according to their specifications. The filtered air is then forced into the cleanroom. Additionally, contaminated air within the cleanroom is forced outside the room by registers, or it is recirculated back into the filters, and the process restarts.

WHO NEEDS A CLEANROOM?

There are a wide variety of reasons that a company may need a cleanroom. If you’re manufacturing something that is easily affected by contaminants or particles in the air for example, it’s likely that you’ll need a cleanroom. If you’re not sure, or if you’d like an estimate, give the experts at Angstrom a call. Here are a few common reasons you might need a cleanroom, and some common industries that regularly use cleanrooms:

Manufacturing Companies

Research Facilities

Pharmaceutical Companies

Medical Laboratories

Electronic Part Production

What is a sandwich panel?

In some sectors of industry, the construction requirements can be critical for a building project. Stud partition construction is a ‘dry process’, with no water needed for the construction materials. A dry process requires only the assembly of the structure and fixing of the cladding (here, the sandwich panels) with screws.

Traditional masonry construction uses ‘wet processes’, which require significant amounts of water to make the mortar for bricklaying, concrete for casting or the plaster for rendering.

Some sectors of industry, like wood processing or pharmaceutical manufacture, require fixed and controlled relative humidity levels, which preclude wet construction processes.

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 and chemical industries.

A pass box is designed in two different types; static and dynamic, it is the user specific requirement which decides the right design configuration. The difference between these two is explained as:

DYNAMIC PASS BOX (DPB)

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

STATIC PASS BOX

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.
