WAAL GFR Series Air Filter Regulator - 2-in-1 Filtration + Pressure Regulation for Reliable Air Preparation
The WAAL GFR Series is a 2-in-1 pneumatic component that integrates an air filter and a pressure regulator into a single compact unit. It is the "F+R" part of an FRL assembly, designed to remove solid particles and moisture from compressed air while maintaining stable downstream pressure.
Key Common Features:
Integrated 2-in-1 design - reduces parts, leak points, and installation space
Embedded square pressure gauge - allows real-time pressure monitoring while saving panel space
Press-in self-locking adjustment knob - prevents accidental pressure changes caused by external interference or vibration
Balanced valve design - ensures stable pressure regulation with minimal drift and excellent pressure characteristics
Unique spin-flow diversion structure - creates centrifugal separation for superior water removal efficiency
Dual filtration accuracy options - 40μm standard, 5μm available for higher cleanliness requirements
Three drain types - manual (standard), differential semi-auto, or fully auto drain
Low pressure version available - up to 0.4MPa max for pressure-sensitive applications
Die-cast aluminum body with corrosion-resistant finish - rated for continuous industrial use
Polycarbonate bowl with metal guard - impact-resistant and safety compliant
Modular design - compatible with other WAAL G Series FRL components (GF/GL/GFC)
Thread options - G, PT, NPT available for global compatibility
Certifications - ISO 9001, CE, RoHS compliant
