RGL Series Gas Filter – Stainless Steel Reusable Filter Element
The RGL series gas filter is an essential component of gas transmission and distribution systems. It is typically installed at the inlet of gas equipment such as pressure regulators, valves, flowmeters, and pressure gauges to remove dust, particles, and contaminants from gas streams, ensuring normal operation and protection of downstream equipment.
