The HNE series gas source processing components are actually metal cup shaped in the E series. E.MC has been producing E series gas source processing components for over 5 years, and the production technology and various component matching are now very complete and mature, becoming another pillar product of E.MC. The metal cup integrates the water cup (oil cup) and its protective cover, and can better protect the components from external damage. The various functional attributes of the HNE series are basically the same as those of the E series. From 3000 to 5000, automatic drainage floats can be equipped, while 2000 cannot. This series of products is important for sales in the Americas and Europe, and is very popular.
