Contamination through people is one of the biggest concerns in a controlled environment of a cleanroom. Even the tiniest equipment or particles on the clothes can compromise big projects or operations. So, to protect the cleanrooms, one of the most efficient tools is the air showers produced by the top air shower manufacturers. It is a system which makes sure that the material and personnel will meet all the contamination control standards before entering the space. In this article, we will see how the Air washer unit works, which construction and design options are available and why they play a vital role in the cleanroom contamination prevention.
Definition of an air shower unit in a cleanroom
Renowned air shower manufacturers create air shower units as a special entry system for eliminating all the loose particles from the materials, equipment, or personnel. With the help of high-velocity HEPA filter air jets, air showers decrease the threat of cleanroom particle contamination. You can use the Air washer unit in stringent cleanroom surroundings, which will be in compliance with ISO Class 5 and 6 standards.
Different Varieties of air showers by the top air shower manufacturers
The requirements of each cleanroom are different from those of the others. Thus, the air shower manufacturers offer different types of units applicable for cleanrooms with numerous applications and layouts.
- Standard
Standard air washer units are perfect for entries that allow only a single person, with restrictions on the ceiling height.
- Tunnel
Tunnel air showers are the extended systems that help several people to enter the cleanroom all at once.
- Low-profile
These air showers come with a space-saving design and are perfect for cleanrooms with limitations in the ceiling height.
- Material Entry
This type of Air washer unit comes with a special design to decontaminate tools, equipment and carts before entering the cleanroom.
Working principle of an air shower
Air shower units help in creating a controlled transition zone before materials or personnel enter a cleanroom by stripping away the unwanted particles in the following way.
- Entry
Individuals can enter the enclosed chamber before going to the clean room.
- Activation of the air jet
A nozzle blasts a high-velocity HEPA-filtered air at a speed of up to 8000 ft per minute. It helps to dislodge all the unwanted particles from the skin and garments.
- Cycle time
The cycle time for the air shower is from 15 seconds to 30 seconds. This time is long enough to eliminate all the contaminants with no delay in the workflow.
- Occupancy limit
Air shower manufacturers design some products for accommodating a single person, while other air shower units can accommodate several people at one time. Thus, it is vital to follow the protocol of every air shower; otherwise, there can be a huge risk of contamination in the cleanroom.
- Exit
After the air shower cycle is complete, it will automatically release the doors and will allow the materials or the personnel to enter the space with no risk of contaminants.
Common materials for air shower construction
Some of the most common materials for the construction of an air shower unit include:
- A cost-efficient and versatile alternative is plastic laminate
- A lightweight alternative with outstanding resistance to corrosion is painted aluminium
- An easy-to-clean and highly durable option is stainless steel
FAQ
How do air showers protect the integrity of the cleanroom across various industries?
The air shower units manufactured by the top air shower manufacturers are implemented in various sectors, but there are some industries where getting rid of every contamination is of high importance. The industries where air showers have a key role to play include pharmaceuticals, medical devices, and semiconductor manufacturing. You can decrease the load of any contamination at the entry point, downtime likelihood and enhance product quality with the use of an Air washer unit.
End words
The cleanroom efficiency is dependent on the contamination control ability. Air shower manufacturers produce the best units, which act like a frontline defense in contamination controlling. Removing all the particles that might cause contamination before entering the cleanroom helps to protect its integrity and ISO standard compliance. With various features, configuration numbers and construction materials, you can customize the air shower units as per your requirements.
