The clean booth’s switching power supply requires segmented control.


Clean booths are primarily used as ideal mobile workstations for sampling and material transfer in industries such as biopharmaceuticals, food processing, and electronics. Compared with other cleanrooms, clean booths represent a cost-effective solution that delivers a high level of cleanliness.

Moreover, since this type of purification equipment features a steel-frame design, it is highly portable and classified as a simple-to-clean device.

Clean booth structural composition

The clean laminar flow hood is mounted on a frame assembled from specialized cleanroom aluminum alloy profiles. Its top is sealed with a blind‑plate valve, ensuring an airtight joint, while the perimeter is enclosed with antistatic curtains or antistatic acrylic panels. At the base around the perimeter, a positive‑pressure exhaust system and other measures are employed to maintain the cleanroom’s cleanliness level within the range of Class 100 to Class 10,000.

Below, we will provide a detailed description of the role that clean booths play in purification projects:

1. The external structure of the clean booth can be customized to meet specific requirements, with the main support frame constructed from high‑quality thick steel plates with electrostatic powder coating, or alternatively from all‑stainless‑steel panels and aluminum profiles, among other materials.

2. The department can be equipped with either a centralized control system or an automated control system that allows each operator to select one of two options.

(1) Centralized Control System: Convenient operation and management options available.

(2) Each control unit: can reduce energy consumption and lower operating costs.

Next, let’s take a look at how to maintain a clean booth:

1. Wipe daily with alcohol to keep it clean.

2. With regard to employee conduct, the clean booth’s switching power supply should be operated in segments to ensure that a circuit failure does not result in total system shutdown. In the exhaust system, employees must not insert pens or other objects into the air supply outlets, as this could cause the delicate filter paper to tear, compromising the cleanliness of the entire simple cleanroom. Additionally, antistatic curtains and roller blinds require careful handling; even if subjected to impacts or dropped items, they may deform or become damaged with daily use.

3. Personnel entering the clean booth must wear antistatic, dust‑free garments, caps, and shoes to prevent contamination of the indoor air.

4. During operation, the power switch of the clean booth must be turned on ten minutes in advance to allow personnel to enter and begin work.

5. The filtration unit shall be regularly cleaned and replaced.
