Watts F105-04BJ Filter

Upgrade your pneumatic air system with the Watts F105-04BJ, a contractor-grade 1/2 inch compressed air filter engineered for high-demand HVACR and industrial applications. This 40 micron particulate filter provides essential point-of-use protection, effectively capturing pipe scale, rust, and bulk moisture that can compromise downstream pneumatic components. Built with a durable polyurethane bowl and guard, this unit offers 360-degree visibility for easy condensate monitoring while maintaining the impact resistance required on active jobsites. This model is a direct cross-reference for 1372125 and 21-513, ensuring seamless integration into existing Parker Watts QUBE modular systems. With a high-flow capacity of 120 SCFM and a maximum operating pressure of 150 PSIG, it delivers consistent performance without significant pressure drops. For technicians managing large-scale air preparation, the Watts F105-04BJ is a reliable choice for maintaining air quality and reducing mechanical wear in sensitive pneumatic circuits.

• Enhanced Filtration Accuracy: The 40 micron element removes heavy debris and water droplets to prevent clog-related downtime.
• High Flow Performance: Supports up to 120 SCFM at 100 PSIG, making it ideal for high-volume NPT air line filter applications.
• Modular Compatibility: Features 1/2" NPT ports and works within the QUBE series for easy pairing with regulators and lubricators.
• Visual Inspection: The wraparound sight gauge on the transparent bowl guard allows for quick status checks of liquid levels.
