- LED lighting function of ductless fume cupboard: it’s equivalent to 10W fluorescent lamp, does not produce heat.

The main features of ductless fume hoods include energy efficiency, flexibility, environmental friendliness, safety, ease of operation, low maintenance costs, and diverse operating modes.
1. Energy saving: The ductless fume hood does not require energy consumption, nor does it require fresh air in the experimental room, thus saving a lot of energy. Due to the lack of external pipelines, it avoids the energy loss of air conditioning caused by traditional fume hoods due to exhaust.
2. Flexibility: The ductless fume hood eliminates the need for a laboratory room ventilation duct system, saving installation costs and making it easy to move and rearrange the laboratory. Its design allows it to be placed on a desktop or equipped with a mobile wheel base, making it suitable for any complex experimental location.
3. Environmental friendliness: Using activated carbon and other materials to adsorb chemicals will not pollute the environment. Through an efficient filtration system, toxic and harmful gases are inhaled upwards, filtered, and returned to clean air indoors, effectively purifying the laboratory air.
4. Safety: Real time detection of surface wind speed and filter saturation level through a continuous and reliable detection system ensures operational safety. The design ensures that chemicals will not overflow, and the main wind direction is from bottom to top, so that all the air inside the cabinet is filtered through the filter.
5. Ease of operation: The system is easy to operate, with a timer to turn on and off the fan, the ability to reset the filter service time, and a low wind speed alarm function; Touch screen design with pre entered product instructions for easy operation.
6. Low maintenance cost: The installation and operation costs of ductless fume cupboard are much lower than traditional fume hoods, and the annual expenditure is mainly on replacing filters, with negligible energy consumption.
7. Diversified operating modes of ductless fume hood: Different filter combinations can be used for various chemical experimental needs in ordinary laboratories and clean rooms, including various gas, liquid, and dust operations.
