As more and more laboratory users begin to choose ductless fume hoods, the net gas storage cabinet manufacturers summarize the following differences between the new fume hoods and the traditional fume hoods: 1 , whether it is efflux: The clean air fume hood does not need external piping, built-in fan and filtration, and directly extracts and filters the exhaust gas; Ordinary fume hoods need to be piped to the outside, and the fan is usually placed on the roof; 2 , the amount of work: The equipment of the Burns Clean Air Fume Hood can be installed in just half an hour, and can be used by plugging in the power; Ordinary fume hoods need to start from the design, drilling, installation, laying pipelines, roofing fans; 3 , energy consumption: The energy of the Burns air purifying cabinet is from 30W to 120W, and the energy consumption is almost negligible; The power of ordinary ventilation cabinet fans ranges from 1500W to tens of thousands of watts, and the energy consumption cost is huge; 4 , air conditioning wind consumption The cycle of the Engas air-conditioning fume hood does not require air to be vented outside, no need to add air conditioning equipment and consume air-conditioning air; Ordinary fume hoods discharge indoor air-conditioning air according to different exhaust air volumes, and need to add corresponding air-conditioning equipment, which may cause indoor negative pressure and affect the working environment; 5 , noise The BioNS air-purifying fume hood is only 41 decibels. It is very quiet and does not have any impact on other operations in the laboratory, and can guarantee the accuracy of weighing one hundred thousandth of the balance; Ordinary fume hoods have large noise and vibration, and cannot be weighed by the balance; 6 , the service life A Penins clean air fume hood can be used for more than 10 years under non-extreme conditions, easy to move, and can be reused in laboratory operations; Ordinary fume hoods are prone to aging, and retrofit labs are not suitable for reuse; 7 , maintenance The Biansi fume hood is easy to maintain and only needs to check the lines and switches for easy troubleshooting. Ordinary fume hoods involve the design of the ducts, lines and air ducts of the entire building. If there is a problem, it is difficult to check and it is difficult; Most of the above are the advantages of the clean air fume hood. Of course, the common fume hood also has the advantage that the new fume hood can't match. 1 , applicability Ordinary fume hood can be adapted to any dose, experimental operation at any frequency; The clean air fume hood is only suitable for small and medium dose operation; 2 , consumables cost The net gas type fume hood has some consumables costs, although it can completely offset the energy consumption of the fume hood, and can have a balance; There is no consumable cost after installation of the common fume hood; Feed Additives,Tocopherol For Feed Additive,Animal Feed Additive,Feed Additive Vitamin E Allied Extracts Solutions , https://www.alliedbiosolutions.com
