This Vevor filter regulator lubricator combines air filtration, pressure regulation, and lubrication in one compact FRL unit for compressed air systems. It uses a 5 μm brass filter element to help remove moisture, impurities, and particles while supporting stable airflow and pressure control. The semi-auto drain design helps discharge accumulated water when the compressor stops working. Built with a poly bowl and metal guard, it is suited for garages, workshops, auto repair, spray painting, and general home improvement use.
