The working principle of a clean air fume hood is mainly divided into the following four parts:
1. Air inlet
Air can be directly drawn from the laboratory into the fume hood, creating negative pressure. The stable surface air velocity forms a natural barrier to isolate users from the chemicals they are handling.
2. Comprehensive filtration system
The fan system inhales toxic and harmful gases upwards, filters them, and returns clean air indoors. The excellent control concentration of the cabinet can ensure that the chemical gases inside the cabinet will not return indoors, causing pollution.
3. Clean laboratory air
Configure different filters according to different operations to effectively filter toxic and harmful gases, purify laboratory air, remove chemical residues and odors, and improve laboratory cleanliness levels.
4. Purifying the surrounding air
The continuous filtration efficiency of the fume hood can help purify indoor air.

Product features of clean air fume hood:
1. Metal components: The main material is high-quality cold-rolled steel plate with a thickness of ≥ 1.2mm, coated with electrostatic powder coating and durable chemical resistant lead-free coating to maintain high smoothness and minimize the effects of corrosion and moisture.
2. Cabinet: The main material is ≥ 6mm acrylic board with good weather resistance and excellent chemical resistance. It is not easy to age, colorless and transparent, transparent throughout, visually comfortable, and beautiful.
3. Seven inch LCD touch screen display, real-time temperature and humidity environment monitoring, fan monitoring, VOC concentration environment monitoring, and integrated alarm system.
4. Using high-quality centrifugal fans, with a current of 24 volts, a maximum air volume of 620m3/h, a speed of 3000 revolutions per minute, stable performance, quietness, and no sparks or static electricity.
5. Efficient filtration system, arranged and distributed according to particle size, following ASTM standards, effectively targets acidic gases and organic gases, with strong adsorption capacity. High efficiency HEPA filters are used for particles, with a filtration efficiency of 99.995% for particles larger than 0.3um. The top can be equipped with a filtering module system according to experimental requirements to meet various different experiments. Optional organic filters (for adsorption of organic solvents), ammonia filters (for operation of ammonia reagents, organic reagents), inorganic filters (for adsorption of both organic solvents and inorganic acids), HEPA filters (for adsorption of solid powders, strong ability), formaldehyde filters (for operation of formaldehyde reagents, organic reagents).
6. LED lighting does not generate heat, and its safety does not affect the temperature of the experimental environment. It is energy-saving, environmentally friendly, and has a long lifespan.
7. Epoxy resin countertops have chemical stability, corrosion resistance, good impact resistance without damage, excellent high temperature resistance, integrated transparent core, long service life, no delamination, no expansion, and no cracking.
8. No need to install pipeline engineering, easy installation, no exhaust gas discharge, new environmental protection.
9. Can be placed on a desktop or configured with a mobile wheel base, convenient and flexible, suitable for any complex experimental location.
