Strict contamination control is essential for pharmaceutical manufacturing, biotechnology, etc. An is one such effective solution that helps prevent the entry of airborne dust and other particles into cleanrooms. These systems can help to remove contaminants from personnel and clothing before entering a cleanroom, using high-velocity, filtered air.
Understanding the concept of an air shower cleanroom
An air shower is a special room fitted with a shower of air at the entrance of a cleanroom or controlled production room. It filters the air and traps dust, fibres or other loose particles from people or clothing before they can enter the clean environment through high-velocity jets of filtered air. The particles are then gathered by an air-filtering and circulating system.
The basic components of an air shower usually comprise a stainless-steel or other appropriate enclosure, high-efficiency particulate air (HEPA) filters, high-powered blowers, air nozzles, sensors and an automatic door interlocking system.
Air Showers are widely used in cleanrooms for various applications:
The air shower cleanroom is a facility where the level of airborne contamination, temperature, humidity and other environmental factors are controlled. Loose particles can be minimised on entering the building with air showers. They are especially useful in places where even low levels of contamination can impact the quality of the products or efficiency of production.
Air showers can be used in a designated area to help with contamination control in the pharmaceutical production line. They are used in electronics manufacturing to reduce particle contamination, which can impact the sensitive components. Air showers should not be used instead of proper gowning, cleaning practices or validated cleanroom controls, however.
Some of the key features of a modern air shower cleanroom system are:
There are a number of important points businesses need to take into account when choosing an air shower.
- High-efficiency filtration: HEPA filters capture particles in the air to provide clean air. Filter specifications will depend on the cleanliness requirements of the facility.
- High-velocity air nozzles: These nozzles are strategically placed to blow filtered air at clothing and other mucous membranes, which causes free particles to be dislodged.
- Easy to operate controls: Digital control panels, cycle timers, sensors, and easy operating indicators make the equipment easier to operate.
- Hygiene, durability and ease of cleaning are provided by the stainless-steel interiors and appropriate exterior finishes.
- Energy-efficient operation: Energy-efficient blowers, controls and airflow systems can help maintain energy savings.
Selecting a trustworthy air shower manufacturer is vital
Choosing the proper equipment supplier is a crucial step in creating an effective cleanroom facility. A good air shower manufacturer will be familiar with the unique needs of each manufacturing sector and be able to provide air shower solutions that fit the layout and contamination control goals of the facility.
When selecting a manufacturer, companies should consider the quality of the construction, specifications of the filter, airflow, control systems used, and documentation for compliance. Also, determine if the manufacturer can design the machine to fit the space and use that is available. Also, find out if the air shower manufacturer will make adjustments to the dimensions, nozzle configuration and operating cycle to fit the application.
Installation help, commissioning instructions, maintenance instructions, spare parts availability, and after-sales service are all important as well. The ability to provide technical support from the initial purchase to the end of the equipment’s life can be invaluable to businesses when it comes to ensuring that the equipment is running at its best and avoiding unnecessary downtime.
Any cleanroom project involving new cleanroom spaces should also consider integration with existing cleanroom doors, gowning rooms, employee flow, and HVAC systems.
The use of air showers in various industries
A few industries require controlled manufacturing and research environments, and this is where air shower cleanroom systems are used.
They are used in the pharmaceutical industry to help with contamination-control measures in the manufacturing and packaging sections. These are incorporated in the entry controls of biotechnology facilities for designated laboratory and production areas. Air showers are employed by the electronics and semiconductor industry to minimise particle contamination in sensitive areas.
These systems can also be used in food processing and special packaging facilities where controlled environments are desired. When extra particulate control is needed for research laboratories or medical-device manufacturing units, air showers are helpful.
Conclusion
An air shower cleanroom system is one of the major components of contamination control in industries where a clean and controlled atmosphere is required. It prevents the release of loose material from people and contributes to the existing hygiene measures.
