According to the moving direction of airflow, the primary air filter device, then the device end valve, oil mist device. The main activity direction, can not put the import export.

Optimal vertical device for pressure reducing valve.

    The blow pipe in the dirt before installation, take the valve on the washing of mineral oil.

The slide part is marked to be coated with lubricating oil, to ensure that the valve stem and diaphragm are concentric.

    To extend valve life, when not in use should relax the handle back to zero, to avoid deformation of the parts are pressed for a long time, influencing the regulation of pressure accuracy.
