universal extraction arm fume hoods,Laboratory Fume Extractors

 Extractor Arm Fume Hoods are primarily used for local fumes, odors and air streams. Most labs use a 2″, 3″ or 4″ diameter arm. The size of the arm is determined by the airflow that you need.

Our extractor arms feature a versatile bench, ceiling or wall mounting capability so you can place the arm where it suits you best. From self-assembly kits to tailor-made solutions, our arms are available in self assembly kits, which include a fan and filter, a fan speed controller, hoses, table bracket and connectors. The kit provides a quick and convenient solution for creating a fume-free workplace.

Six different extractor arm fume hoods kits are available. We have both the products and the experience required to create customized extraction solutions, large or small.

The main function of the universal cover is to emit exhaust gas and smoke, dust and other smudgeable substances. The Century Universal Cover is made of PP polyethylene integrated die stamping. The product is resistant to acid and alkali corrosion, high temperature and long service life, 360 degree no dead angle rotation, convenient and light, and can easily collect exhaust fumes. Widely used in laboratories, laboratories, pharmaceutical plants, hospitals, universities, research institutes and other places. (If there is a product need, please send electricity to the century, the price is favorable. Thank you!)

The use of universal suction hoods is so extensive because the universal hood can be used to collect all exhaust gases and fumes within the span range. The air outlet adjusts the air inlet to adjust the air volume according to the site conditions. Its good telescopic hover function is a must-have item for many companies polluted by smoke.

The exhaust system of the fume hood can be divided into two types: centralized and decentralized. Centralized is a system of one or two floors of fume hoods, or the entire experimental building is divided into two systems. It is characterized by less ventilation, less equipment investment, and a certain degree of adaptability to the number of fume hoods, as well as the change of position. However, due to the large system, the air volume is not easy to balance. Although each fume hood is equipped with a regulating valve, it is inconvenient to use and it is not easy to achieve the intended effect. If the system duct is damaged and needs to be repaired, the entire system’s fume hood cannot be used. Therefore, laboratories that used centralized systems have been replaced with decentralized systems. Decentralized is the integration of a fume hood or several fume hoods in the same room into an exhaust system. His characteristics are: the fan can be turned on and off according to the working needs of the fume hood, mutual interference, easy to achieve the desired effect, and more energy-saving than centralized, because the centralized system, as long as a fume hood is in use, Start the big fan. Due to the small size of the system, the air volume is small and the resistance is small. Therefore, the air volume and wind pressure of the fan are not large, and the noise and vibration are correspondingly small. Another feature of the decentralized type is that it is easy to treat harmful gases that discharge different properties. The disadvantage is that the number of ventilators is large and the system is many. If the ventilator is concentrated in the ventilator room, the investment will increase. If the ventilator is dispersed and installed on site, although the investment of the ventilator increases, the investment of the duct Can save, and finally the total investment does not necessarily increase. Decentralized is recommended.
