Material and durability The regulator shell is predominantly polycarbonate, providing wear resistance, aging resistance, and longterm durability. This sturdy material helps resist damage and extend the product's lifespan for reliable performance over time. Automatic moisture drainage for stable operation Equipped with differential pressure drainage technology, this regulator operates automatically with no manual intervention. It responds to excess moisture and precisely controls pressure thresholds, delivering stable, uninterrupted performance. FRL combo with effective filtration This compressed air filterregulatorlubricator FRL combo uses a copper filter element with 25–30 μm filtration precision to efficiently remove impurities from compressed air. It is ideal for use with pneumatic tools, machinery, or systems that require clean, regulated air. Easy to use with simple pressure adjustment Pressure adjustment is straightforward in three steps: 1) Pull up the cover 2) Rotate to set your desired pressure (following cover instructions) 3) Press the cover down to lock No special tools or expertise required. What it does and why you need it Provides clean, regulated air for downstream tools and equipment, protecting components and improving performance. Combines filtration, regulation, and lubrication in one unit for compact, integrated air treatment. Durable polycarbonate housing supports rugged use in workshops and industrial settings. Automatic moisture management reduces maintenance and downtime. Compatible applications and scenarios Workshop tools: drills, impact wrenches, sanding tools and other pneumatic equipment that require clean, steady air. Automated machinery and production lines: actuators, cylinders, and pneumatic controls that benefit from stable pressure and dry air. Finishing and painting processes: systems that demand dry, filtered air to improve coating results and equipment longevity. Usage and maintenance notes Designed for standard compressed air systems requiring clean, regulated air. Ensure regular checks of the regulator's cover position and pressure setting as part of routine maintenance. No tools required for setup; follow the threestep pressure adjustment process for quick changes.
