Budget-friendly in-line filtration with ring-lock quick-release head—painted mild-steel body in CTC blue.
GNG filters deliver reliable inline filtration at an economical price point. The ring-lock quick-release head design enables fast screen removal and cleaning without tools, while the painted mild-steel construction keeps upfront costs low.
Representative image — GNG uses ring-lock head
Simplified body and ring-lock head design reduce manufacturing complexity and cost.
Quick-release clamp on ring-lock head for fast screen removal and cleaning.
Blue epoxy finish matching the BIG line for durable corrosion resistance.
Ring-lock head requires pressure to complete the seal; do not use on suction-side service. GNG filters are designed exclusively for pressurized applications.
