What is the Difference Between Dynamic and Static Pass Through Box Clean Room?

Static Pass Through Box Clean Room

If the class or grade of the two clean room areas is the same, a static pass box is taken into account. It helps in the movement of air from one clean side to the other clean side.

In processes having high-safety requirements and zero contamination permission, a static pass box is used. In other words, you can also call it a passive pass box.

The main features of the static pass box include disinfecting UV light, stainless steel 304 or 316 or 316L material of construction, interlocking doors, viewing panel, internal coving, audiovisual alarm, and no sharp corners.

Dynamic Pass Through Box Clean Room

If the two clean rooms have either the same or different cleanliness levels, a dynamic pass box is considered. In other words, it is also called an active pass box.

The basic features available in a dynamic pass box are the same as that of a static pass box but some additional features are also available like HEPA filter and pre-filter installation.

These filters provide improved cleaning results to ensure that most of the clean air is fairly distributed in the environment.

Dynamic pass box stops the entry of contaminants by taking in clean air. It also has a re-circulated filtration system and GMP complying with designing instructions to meet your application demands.

Static Pass Through Box Clean Room Outstanding Features

What is the Role of Fitting a Magnehelic Gauge in your Pass Through Box Clean Room?

The purpose of fitting a Magnehelic gauge is to stay aware of non-corrosive gas pressure or low-air situations using its easy frictionless Magnehelic movement.

The indications can be either classified into the negative (vacuum), positive or differential categories. The special design shows excellent resistance to vibrations, shocks, and over-pressures.

The common use of this gauge is to find out the pressure of the blower and the fan in the Pass Through Box Clean Room.

Also, you can use it to know the air velocity, pressure drop across the orifice plates, filter resistance, furnace draft, pressure in fluidic or fluid amplifier systems, and levels of liquid with the bubbler systems.

Magnehelic gauge is also helpful in finding out the automatic valves and gas-air ratio controls and is also used in medical equipment for monitoring respiratory pressures and blood levels.

What is the Purpose of Installing a Pre-filter in your Pass Through Box Clean Room?

For removing very large particles (like dirt, dust, and hair) an air filter, generally known as a pre-filter is used.

In any air purifying system, the basis of the air filtration process lies on this pre-filter.

The main purpose of this filter is to keep the clean room HEPA filters protected from getting damaged or clogged up by the encounter of large particles. Clean main filters are a good indication of their capacity to trap microscopic pollutants.

As soon as the large particles step into the air filtration system, the large particles are instantly trapped by the pre-filter before letting the air enter your Pass Through Box Clean Room.

You can compare the working of a pre-filter to the normal sieve. Only air particles are allowed to pass through the netting or holes of the sieve whereas large particles are left trapped on the pre-filter surface.

The main reason here is the mesh size of the pre-filter and the main filter present in your Pass Through Box Clean Room.

The two main applications of a pre-filter are: trapping large-sized particles and the second one is to improve the service life of the main filters.

Pre-filters also provide protection to the main internal features so that efficient contamination of small-sized contaminants takes place.

This is done for improving the efficiency and longevity of the last main filter, or the HEPA filter box.

What are the Benefits of 304 Stainless Steel Construction of your Pass Through Box Clean Room?

The 304 stainless steel construction of your Pass Through Box Clean Room can benefit you in many ways, out of which some major benefits include:

Impact Resistance

The austenitic microstructure helps in providing a high degree of toughness, making this steel capable of withstanding sensitive environmental conditions, particularly in healthcare settings.

Corrosion Resistant

The best thing about stainless steel is that it does not leave any stains. The major reason behind this is its corrosion resistance properties.

As a result, it shows high compatibility for being used in food processing activities or hospital areas. But you should always keep in mind protecting stainless steel from extremely high-temperature exposure accompanied with chlorine and acid contents.

If your application involves the use of moderately concentrated chemicals like sulfuric acid or nitric acid, at normal temperatures then low carbon stainless steel (304L SS) is the best choice for constructing your Pass Through Box Clean Room.

Hygienic

Stainless steel has a hard metallic surface which does not favor the penetration, adherence, or survival of the bacteria. The best part is that you can easily clean the surface and maintain good hygienic conditions.

Largely replaced conventional sink materials are available in type 304 stainless steel, like plastic laminates and aluminum due to their high cleanliness and chemical resistance properties.

Recyclable

The best thing about stainless steel is that it is 100 percent recyclable. We can say that 50 percent of the new steel formed is recycled by remelting the old stainless steel scrap, and ultimately the full life cycle is completed.

What are the Several Types of Ventilation Available in your Pass Through Box Clean Room?

The ventilation available in your Pass Through Box Clean Room can be of different types: mainly active and passive ventilation.

Active Ventilation

The type of ventilation that requires the use of mechanically introduced air for the preservation of air conditions between rooms.

The second step involves the creation of a sink or a bubble to the communicating room which is followed by the dilution of chemicals that are into the box at the time of opening the door of the Pass Through Box Clean Room or maintenance of the area classification.

Passive Ventilation

In passive ventilation, the airflow within the rooms and the pressure differential between the two rooms are used.

Then, the door opening is considered as the motive force that allows the particles to be transferred into or out of the box.

Passive ventilation is the most commonly observed type of ventilation in a Pass Through Box Clean Room.

Turn the particle counter on and record the reading of the particle concentration. But what you should keep in mind is that the sample under observation should have a volume of at least 1-meter cube.

Also, the air present inside the particle counter should comply with the acceptance criteria for grade A airborne particulate cleanliness class.

Why is UV Light Used in your Pass Through Box Clean Room?

UV light rays are non-ionizing electromagnetic radiation having a wavelength range of 240 to 280 nanometers.

The reason why UV light is used in your Pass Through Box Clean Room is that it works as an efficient disinfectant or antiseptic agent that helps in the killing of harmful microorganisms.

The mechanism involves exposure of microorganisms to UV light, upon which their DNA absorbs this harmful energy.

An organism once damaged by UV light is no longer able to reproduce or produce essential proteins and dies immediately. Ultraviolet rays also play a significant role in inactivating viruses.

But you should keep in mind that the number of bacteria killed by UV light is not as per the normal expectations, it is much lower.

UV rays having shorter wavelengths destroy the nucleic acids of the microorganisms ultimately preventing their growth.
