G3/8 Series High-Efficiency Fluid Filter (Model 399-G3/8)
Product Overview:
The 399-G3/8 filter is engineered for industrial fluid systems, featuring compact design for flexible pipeline integration. With multi-stage filtration units, it effectively captures particles above 5μm, maintaining cleanliness of hydraulic oil, compressed air, and coolant. Modular structure enables quick maintenance for continuous operation.
Key Features:
-
Precision Filtration
Dual-layer stainless steel mesh with gradient density achieves progressive filtration while maintaining flow stability. Special surface treatment reduces flow resistance, decreasing working pressure drop by 18% compared to conventional models.
-
Enhanced Sealing System
Self-compensating sealing rings ensure reliable performance across -20℃ to 120℃. Tapered thread connections with anti-loosening design withstand pressure fluctuations from 0.8-25MPa.
-
Maintenance Efficiency
Visual contamination indicator monitors filter status. Tool-free quick-connect design enables fast replacement, reducing downtime by over 40%. Universal cartridge compatibility simplifies parts procurement.
-
Durable Construction
CNC-machined 6063-T5 aluminum alloy body with hard anodized surfaces. 304 stainless steel core support maintains structural integrity in mildly corrosive environments.
