The unique construction makes maximum use of the compressed air and therefore consumes less energy. Large vacuum fl -ows and high levels of vacuum are characteristic of DRMC'

s vacuum generators. DRMC'

s Vacuum generators are compressed air-driven multi stage air ejectors with considerably higher performance than conventional single stage ejectors. The expansion of compressed air is controlled so as to produce maximum energy at minimum pres -sure. The multi stage principle gives very high efficiency and combines large flow with a deep vac -uum. DRMC 真空发生器是利用压缩空气驱动的独特结构制成, 当压缩空气经过真空发生器内部的喷嘴时产生大量的真 空和高真空度. 利用压缩空气驱动, 可以节省能源, 名副其实的达到低碳环保标准. DRMC真空发生器是只要有气源就可以使用, 内部结构采用高效率的多级喷嘴方式, 多级喷嘴方式能满足高真空度 和大流量真空抽气. DRMC提供从小流量到大流量各个级别的真空发生器, 满足不同环境, 不同客户的需求. The advantages of DRMC 特点 Operates just with compressed air 压缩空气驱动 Low noise levels 低噪音 No vibration 无震动 No spark formation 防爆 No heat emission 无发热 No oil mist 无油污 Low energy consumption 节能、低碳、环保 Easy to install 安装容易 Fast response 反应速度快 Compact size and light weight 小型轻便 Minimal maintenance 极少的维修 Reliable 互换性强,可替换真空泵 真空原理示意图 ?Specifications subject to change without notice.
