How to choose the right clean room vacuum cleaner? What are the requirements for clean room vacuum cleaners?
When choosing industrial vacuum cleaners for clean rooms, many people do not realize the importance of vacuum filtration systems. In fact, what you really need is a super filter instead of a vacuum cleaner, and because the filtering systems of existing vacuum cleaners are very different, you must figure out what you need when choosing a vacuum cleaner that meets your requirements.
First of all, all vacuum cleaners used in clean rooms must have a HEPA filter function to ensure that 99.97% of particles with a size as low as 0.3 microns are filtered out. In addition, the HEPA filter must be installed behind the motor to filter the exhaust airflow, which is very important. The commutator and carbon brush of the motor will generate dust, and if the exhaust airflow is not filtered, the dust will directly enter the clean room environment. Please note: not all HEPA filtration systems are the same.
For example, a multi-step classification filter system uses a series of increasingly sophisticated filters that can capture particles as they pass through the vacuum cleaner. The largest particles can be captured with a relatively ordinary filter, and to capture the smaller particles, a more sophisticated HEPA filter must be used. This multi-stage system can protect the HEPA filter from clogging and excessive wear, maintaining optimal performance. (Once equipped with ULPA filter, the system can filter all ultra-small particles, the minimum is 0.12 microns, and the efficiency is as high as 99.999%).
In addition, if your vacuum cleaner filter system uses an extra-large filter, the airflow is slowed down due to the larger surface area, thereby optimizing the air-to-cloth ratio. In this way, the vacuum cleaner can easily absorb larger debris without requiring a lot of maintenance even after its normal use period.
In addition to these filtering systems, vacuum cleaners used in clean rooms are best made of materials that do not produce particles. For example, using a non-porous stainless steel vacuum cleaner with smooth hoses and connectors, workers can quickly wipe and clean the equipment with a rag, and complete cleaning and confirmation faster and easier. Although many vacuum cleaners can withstand autoclaving, the manufacturer of the vacuum cleaner must first confirm before proceeding with this project, otherwise, the equipment may be damaged.
The overflow response must also be considered when purchasing a vacuum cleaner. At least one vacuum cleaner can perform both dry and wet operations. If you are interested in our products, you can click here: Wet And Dry Vacuum Cleaner Suppliers.
