Quick Procurement Summary - The AS200-F series is a point-of-use air filter regulator designed to remove water, dust, and oil mist while stabilizing output pressure for spray guns and pneumatic tools. It fits buyers who need cleaner finishes, more consistent tool performance, and a compact 1/4" compressed-air accessory suitable for OEM, wholesale, or private-label programs.
Why Buyers Add a Filter Regulator Instead of Running Air Directly
Cleaner Air Path for Better Finish QualityMoisture and oil mist can damage paint finish quality, contaminate wood surfaces, and reduce consistency in air-powered work. Buyers in finishing categories need this page to answer that problem quickly.
More Stable Pressure at the Trigger PointInstead of relying only on upstream compressor settings, a point-of-use regulator helps maintain more predictable working pressure where it matters most: right before the tool or spray gun.
Visible Maintenance with Transparent BowlA transparent PC bowl lets users visually confirm water accumulation before it becomes a hidden system issue. That is useful for field checks, workshop education, and retail demonstration.
Easy Channel PositioningThis product can be positioned across spray finishing, pneumatic tool accessories, and workshop compressed-air care, making it useful for distributors building a broader accessory range.
Core Technical Features
Moisture Control
Transparent PC Bowl for Visual Water Check
The clear polycarbonate bowl makes daily inspection faster. Users can see water accumulation and drain it before liquid moisture reaches spray guns, sanders, or air motors.
Pressure Stability
Point-of-Use Regulation for Consistent Tool Behavior
Pressure consistency matters for spray quality, tool RPM, fastening feel, and sanding results. This integrated regulator helps users set and maintain a more controlled working pressure near the actual end use.
Housing Material
Aluminum Body for Daily Workshop Durability
The aluminum body supports durability expectations across detailing bays, woodworking shops, and pneumatic maintenance stations. It is suitable for buyers seeking a more professional compressed-air accessory than low-grade commodity fittings.
Applications and Industries
Automotive DetailingHelps reduce moisture contamination before spray-gun use and paint-finishing work.
WoodworkingSupports cleaner air delivery for pneumatic sanders, nailers, and finishing tools in dust-sensitive environments.
Industrial MaintenanceUseful for point-of-use pressure control and moisture reduction in compressed-air maintenance routines.
The AI304-R1/R2 model is a point-of-use air filter regulator used across a few professional settings. In automotive detailing, it filters moisture and particulates out of the air line before it reaches the spray gun, which keeps finishes clean. In woodworking, it removes moisture and dust from compressed air lines. For industrial maintenance, the aluminum alloy body holds up to daily workshop handling while regulating pressure between 90 and 150 PSI, with a 200 PSI maximum.

FAQ for B2B Buyers
What does an air filter regulator do?It combines two functions: removing moisture and contaminants from compressed air, and regulating output pressure before the air reaches a spray gun or pneumatic tool.
Who is the AS200-F series suitable for?It is suitable for spray-gun accessory distributors, automotive detailing channels, woodworking supply buyers, and pneumatic maintenance product lines.
Why choose a filter regulator instead of a regulator only?A regulator only controls pressure. A filter regulator also helps remove water and contamination, which is important when finish quality or internal tool protection matters.
Does LEMATEC support OEM / ODM or private label projects?Yes. LEMATEC supports OEM / ODM discussion, branding direction, sample validation, and wholesale supply for compressed-air accessory projects.
How does the AI304-R1/R2 Filter Regulator compare to a regulator-only model in workshop use?A regulator-only model controls pressure but does not remove moisture. The AI304-R1/R2 combines both functions in a 118g unit, with a transparent polycarbonate bowl for a visual water check and a push-button drain valve.
Can buyers choose the display option and connection type for the AI304-R1/R2 series?Yes. Buyers can choose an analog or digital gauge for pressure display, and the unit comes with 1/4 inch NPT and PT connections.
