Multifunctional air regulator and moisture filter for pneumatic tools and spray guns Key benefits Prevents moisture contamination that causes uneven atomization and paint defects — more consistent, professional spray results. Removes rust, condensation and other airline contaminants to protect tools and reduce maintenance and downtime. Broad compatibility with a standard 1/4-inch thread — fits most pneumatic tools and spray guns for quick integration into existing setups. What it does best Effective moisture filtration during use so humidity does not mix with your coating or interfere with spray quality. Protects downstream equipment by trapping harmful particles and liquid carryover from the air supply. Designed to meet higher-end spray requirements where consistent atomization and finish quality are critical. Practical features Standard 1/4-inch threaded connection: easy to install on most air hoses, regulators and spray guns. Multifunctional design: combines moisture separation and particulate filtration in one unit to simplify your air treatment setup. Reliable performance for hobbyists and professionals who require clean, dry air for finishing or pneumatic work. Typical applications Automotive painting and refinishing: prevents moisture lines and ensures smooth, uniform clearcoats and basecoats. Furniture and cabinet spraying: keeps finishes streak-free and improves overall surface quality. General pneumatic tool protection: filters condensation and rust before it reaches air motors, sanders, and other air-powered tools. Quick installation tip Install between the air source and the tool or spray gun, using the standard 1/4-inch threaded connection. Periodically check and drain captured moisture to maintain optimal performance. Specifications Thread size: standard 1/4-inch Primary functions: moisture separation and particulate filtration Compatibility: suitable for most pneumatic tools and spray guns This air regulator/filter provides straightforward, reliable moisture control and filtration to improve finish quality and extend tool life without complicated setup.
