In the laboratory environment, harmful gases, dust and other pollutants generated during experimental operations constantly threaten the health and safety of laboratory personnel. Tai Sifeng (Shanghai)'s ductless air purifying fume hood brings a new solution for laboratory ventilation protection with innovative technology.

1、 Innovative working principle, efficient air purification

The top of the Taisifeng ductless air purifying fume hood is equipped with a fan, which creates a negative pressure environment inside the cabinet after startup. When the experiment produces air containing chemical gases and powder particles, it will be quickly sucked into the top. The fume hood is equipped with high-efficiency molecular filters and high-efficiency particle filters to accurately filter harmful substances. For example, for organic waste gas, special adsorption materials in molecular filters can firmly capture it; For small particles, high-efficiency particle filters can block more than 99.7%, and the purified clean air is discharged back into the room, achieving self circulation purification, avoiding pollutant diffusion, and ensuring air safety in the experimental operation space.

2、 Diversified technological characteristics, meeting diverse needs

（1） Flexible installation, saving space

This fume hood breaks through traditional limitations and does not require external ventilation ducts. As long as there is a power outlet, it can be placed in any location in the laboratory. It can be directly placed on the existing experimental platform or paired with a mobile base, and can be adjusted according to the experimental layout at any time. Whether it is a newly built laboratory or an existing laboratory with limited space, it can be easily adapted, greatly saving space and installation costs.

（2） Intelligent monitoring, security upgrade

The cabinet is embedded with two sets of detection modules, one for real-time monitoring of filter saturation status and precise control of service life; Another set is responsible for indoor air quality monitoring. Once the environmental indicators exceed the safe range, the intelligent exhaust system will immediately start, forcing toxic gases to be discharged outdoors. At the same time, the airflow sensor continuously reads the surface wind speed and displays it intuitively on the display screen. The alarm point is set according to the latest occupational health standards to ensure that the experimenters detect abnormalities in a timely manner.

（3） Energy saving and environmentally friendly, the green choice

The ductless clean air type fume hood adopts an internal circulation filtration mode, which does not exhaust air to the outside, avoiding energy waste of air conditioning and reducing greenhouse gas emissions, in line with the concept of green environmental protection. And the overall power consumption of the equipment is low, with no high-power components, significantly reducing long-term operating costs.

3、 Widely applicable in various fields, suitable for multiple scenarios

Suitable for small and medium dose chemical experiments, such as liquid handling, mixing of liquids with dust, and dust handling. In a constant temperature and pressure laboratory, it is possible to accurately maintain stable environmental parameters; The pharmaceutical GMP laboratory strictly ensures a clean production environment for drugs; University teaching laboratories are convenient for students to operate safely. In addition, office building laboratories, clean room forensic histology laboratories, and other places can also use their purification functions to create a safe experimental atmosphere.

Taisifeng (Shanghai) ductless air purifying fume hood creates a safe, efficient, and environmentally friendly working environment for laboratories with advanced technology, becoming an ideal choice for modern laboratory ventilation and protection, and helping scientific research, testing, and other work to proceed smoothly.
