Ventilation ducts preferred Rood air duct plate production and installation as well as other major finished materials, ventilation pipes for industrial and civil buildings ventilation and air conditioning duct, in order to allow air circulation and reduce the concentration of harmful gases, to solve a variety of ventilation ducts collide and coordination of the general principle of "small pipe so that bassoon, there is pressure to make without pressure." Preferred Rood air conditioning ventilation ducts must not go beyond general to limit ourselves. Before construction equipment mains should engineer, will the various types of pipelines, single line drawn on a plan. Each pipeline with a color pen. Duct mainly used in industry and construction, the main application areas related to the electronics industry dust-free plant purification systems, hotels, factories and office buildings of central air conditioning systems, industrial pollution control dust, smoke, oil and other exhaust pipes, industrial environment or job comfort with air hose, gas coal mine drainage gas with drainage systems, environmental control of coal mine return air systems and the like; for more complex civil construction, in design stage, various types of work (HVAC, water supply and drainage , powered lighting and building professionals) should first consult a good spatial separation, set elevation range for each pipeline. Integrated in the intersection point of its elevation, to see if there are inconsistencies, to discover. Lianyungang Rood air-conditioning equipment installation Co., Ltd.
