Double person air showers are an essential component of contamination control in cleanrooms, offering efficient and cost-effective removal of particles from the surfaces of people. They are suitable for a wide range of applications and offer several benefits over single-person air showers, including reduced waiting time, increased throughput, and space and energy savings. When selecting a double person air shower, it is important to consider factors such as the size and configuration of the cleanroom, the level of cleanliness required, and compliance with relevant standards and regulations.

1. What is a double person air shower?

A double person air shower is a type of airlock that accommodates two people at the same time, each standing on opposite sides of the chamber. The chamber is equipped with high-velocity HEPA-filtered air nozzles that blow air over the people from all directions, removing particles from their surfaces. The air is then filtered and recirculated back into the chamber, while the removed particles are collected in a pre-filter or a post-filter.

2. How does a double person air shower work?

A double person air shower works by creating a high-velocity air stream that removes particles from the surfaces of people who enter the cleanroom. The air shower chamber is equipped with multiple nozzles that blow air from all sides, top, and bottom, ensuring complete coverage of the people's bodies. The nozzles are located in the ceiling, walls, and floor of the chamber and are designed to produce a laminar flow of air that is free from turbulence and dead zones. The air is filtered through a HEPA filter with an efficiency of at least 99.99% for particles as small as 0.3 microns, which is the most penetrating particle size (MPPS) for HEPA filters.

3. Why is a double person air shower better than a single person air shower?

A double person air shower is better than a single person air shower for several reasons. First, it allows two people to enter the cleanroom at the same time, reducing the waiting time and increasing the throughput. Second, it reduces the risk of contamination by ensuring that both people are properly decontaminated before entering the cleanroom. Third, it saves space and energy by using a single air shower for two people instead of two single-person air showers. Fourth, it is more cost-effective than two single-person air showers. Finally, it is more convenient and practical for larger cleanrooms with high traffic.

The air shower is the most competitive among Kwang air showers, and it is also one of our most hot sale air showers. Generally, the size of the air shower is determined according to the number of people in the workshop. If there are about 50 people in the workshop, we recommend that you choose to use Kwang double person air shower, so that more than 50 people can pass through in about 10 minutes.

Designed with the dimension of 1400×2000×2100mm, the double person air shower room is actually composed by two single person products. The double person product and the single person product have no difference in function except for the applicable number of people and the volume. The material for interior and exterior body of the product is SUS304 stainless steel. The body of the product is equipped with multiple filters for getting excellent filtration effect. Users can also choose the product with high efficiency particulate air filter (HEPA filter). There are total 24 nozzles with the mouth diameter of 30mm set on the two sides of the product. These nozzles can achieve air shower for two to four persons simultaneously.

FAQs

1. How often do I need to replace the filters in a double person air shower?

The frequency of filter replacement depends on several factors, such as the level of cleanliness required, the type of particles to be removed, and the frequency of use. It is recommended to follow the manufacturer's instructions for filter replacement and maintenance.

2. Can double person air showers be customized to specific requirements?

Yes, double person air showers can be customized to specific requirements, including size, configuration, and filtration efficiency. It is important to consult with a qualified professional to ensure that the air shower meets the specific requirements of the application.

3. Can double person air showers be used for personnel decontamination in hazardous materials handling?

No, double person air showers are not suitable for personnel decontamination in hazardous materials handling. Specialized decontamination equipment and procedures are required for such applications.

4. How do I know if a double person air shower is compliant with relevant standards and regulations?

Double person air showers should comply with relevant standards and regulations, such as ISO 14644, FDA guidelines, and local building codes. It is important to consult with a qualified professional and verify the compliance of the air shower before purchasing and installing it.
