2020年2月13日-EXAIR的303型2-1 / 2 NPT螺纹线Vac气动气动输送机将普通管道转换成用于零件，废料，饰件和其他散装物料的输送系统。它们设计用于食品，化学和制药工艺或可能需要303SS的潮湿和腐蚀性的区域。它们较大的尺寸使其适合长距离输送较大的零件和大量的物料。螺纹线Vac设计为连接到标准管道连接器。
February 13, 2020 - EXAIR’s Type 303 Stainless Steel 2-1/2 NPT Threaded Line Vac Air Operated Conveyors convert ordinary pipe into a conveying system for parts, scrap, trim and other bulk materials. They are designed for food, chemical, and pharmaceutical processes or areas likely to be wet and corrosive which require the 303SS. Their larger size makes them suitable for conveying bigger parts and large volumes of material over long distances. The Threaded Line Vac is designed to attach to standard plumbing pipe couplers.
Threaded Line Vac Conveyors eject a small amount of compressed air to produce a vacuum on one end with high output flows on the other. Response is instantaneous and regulating the compressed air pressure provides infinite control of the conveying rate. Applications include scrap trim removal, material conveying, part transfer, fiber tensioning and filling operations.
2-1 / 2 NPT 303SS螺纹式真空管符合CE标准，并满足OSHA压力要求。完整的尺寸范围是3/8 NPT至3 NPT。螺纹线Vac型号也可提供316型不锈钢，用于要求更高的高温，腐蚀性和卫生环境。
2-1/2 NPT 303SS Threaded Line Vacs are CE compliant and meet OSHA pressure requirements. The complete size range is 3/8 NPT through 3 NPT. Threaded Line Vac models are also available in type 316 stainless steel for more demanding high temperature, corrosive and hygienic environments.
