1. Security

It is difficult to provide comprehensive protection for experimental personnel and real-time safety information during the experimental operation of the external ventilation cabinet. The LED flashing and sound alarm system on the top of the clean air fume hood cabinet can timely reflect whether all operating parameters of the fume hood are running normally, and can receive safety alarm information in a timely manner when encountering danger, protecting the health and safety of experimental personnel.

2. Service life

Ordinary outdoor fume hoods are prone to aging, and due to the installation involving various air ducts, wiring, and the design of the entire laboratory pipeline, once problems arise, they are difficult to troubleshoot and are not suitable for reuse. The clean air type fume hood is a ductless fume hood that is easy to install and move, and can be used for more than ten years in non extreme situations. It can also be reused during laboratory relocation.  

3. Energy consumption

The power of a fan in an external ventilation cabinet ranges from 1500 watts to tens of thousands of watts, and it works for at least 8 to 10 hours a day, consuming a huge amount of energy. The clean air type fume hood mainly circulates clean air after adsorption and filtration indoors. The power of each fume hood ranges from 30 watts to 120 watts, and the energy consumption is almost negligible.

4. Principle

One Control the spread of chemicals into the air from the source

II Working principle of adsorption through molecular activated carbon filter

III Relying on the intermolecular interaction forces

5‌. Efficient filtration system

The clean air fume hood is equipped with an efficient filtration system that can filter out bacteria, particulate matter, dust, etc. in the air, providing a clean and safe working environment for the laboratory. This efficient filtration system ensures that the air quality in the work area meets higher standards, effectively protecting the health and safety of laboratory personnel.

6. Good operating interface

Clean air fume hoods usually have a good operating interface, and the workbench inside the cabinet is stable and flat, making it convenient for laboratory personnel to operate. In addition, the cabinet is often equipped with lighting devices to facilitate experimental operations by laboratory personnel.

7‌. Diversified working modes

The clean air type fume hood has diverse working modes, such as flow regulation mode, wind speed regulation mode, and wind pressure stabilization mode. The design of these modes can be adjusted according to specific experimental needs to ensure the efficiency of laboratory work and the accuracy of experimental results.

8. Reliable security protection system

The clean air fume hood has a comprehensive safety protection system, including filter life monitoring system, air pressure control system, temperature and humidity control system, etc. The design of these systems can protect the safety of the laboratory working environment from multiple aspects and improve laboratory operational efficiency.

9‌. environmental protection and energy conservation

The clean air type fume hood does not require complicated installation projects such as external pipelines, fans, and supplementary air systems. It also has built-in fans, which are efficient and energy-saving. It does not rely on any air conditioning cold or warm air, and does not emit into the atmosphere, which does not pollute the environment and meets modern environmental protection requirements

High efficiency HEPA filters are used for particles, with a filtration efficiency of 99.995% for particles larger than 0.3um.

A ductless fume hood can control the diffusion of chemical gases from the source. The chemical odors generated in the laboratory are evaporated and diffused into the air as chemical experiments occur. The clean air type fume hood can collect the volatile gas in the filtering device in the first time. The clean gas storage cabinet can store chemical reagents in an orderly and standardized manner in the laboratory, absorb toxic and harmful chemical gases evaporated from reagent bottles, and circulate the air inside the laboratory at a processing capacity of 90 cubic meters per hour, improving the air quality of the laboratory while protecting the safety and health of personnel.
