Compact design fits in tight spaces and supports a variety of applications. Its compact structure enables efficient performance even in confined areas. Threeinone functionality combines an air pressure regulator, water filter, and stainless steel adapter in a single unit. This simplifies setup, reduces clutter, and provides a complete solution for your pneumatic system. Lightweight and rustproof materials. Made from plastic and aluminum alloy, this filter is easy to handle and install on all types of pneumatic tools. Adjustable pressure control. The regulator supports 0 to 10 BAR (0 to 150 PSI). The clear dial allows you to monitor pressure and fine tune it with a simple knob turn. Wide compatibility and reliable performance. Designed for use with a broad range of pneumatic tools and applications, delivering consistent pressure and moisture filtration. Use scenarios: Spray painting and finishing with a spray gun, where stable pressure and moisture filtration improve results. Operation of air tools such as impact wrenches and grinders, to protect tools from moisture and maintain steady performance. General workshop air line maintenance, keeping pressure consistent and filtering water for cleaner air delivery.
