PP fume hoods, laboratory fume hood [Huasheng Holdings Group] bulk sales of most laboratory experiments exhaust vented to the atmosphere without processing, so will cause harm to the environment, and commercially available in many laboratories exhaust purification approach, most of them are not in place or even configuration futile, can not effectively deal with the different exhaust gas generated by the different experimental company of new Han pioneer of responsibility for environmental laboratory equipment, in 2011, it launched a comprehensive coated purifying exhaust fume hood personal protection experiments and environmental safety. Design Features: intelligent manipulation, the inner loop purification, multifunctional protective, quick installation cycle purification: independent R & D cycle dedicated one-piece plastic fan motor in direct contact with the acid gas to prevent the danger of explosion of sparks, new makeup air type fume hood: EN-14175-3 design concept to achieve low leakage rate requirements. Product Features: cabinet: PP plastic plate (customized special board) the thickness 8mm resistance to strong acids, alkalis, chemicals, non-corrosive no rust, no spontaneous combustion deflector forming one whole surface ventilation deflector: PP, due to the cabinet gas severity of considerations, design venetian deflector achieve pumping exhaust smoothly highest efficiency noise test: noise test from the the cabinet 1 meter 60 dB below the speed test: cabinet sliding door open test wind speed 0.5M / s over-pumping fan: PP UFO direct connection with strong pumping fan, low noise, high efficiency (patent pending) timer: adjustable electronic timer, set the body running the extraction time
