FISHER 67DFR-25/67DFR-24 Integrated Filter-Regulator for Gas Applications
Product Details
FISHER 67DFR-25 is an integrated filter-regulator designed for precise gas pressure control applications. Manufactured by Emerson, this unit combines filtration and pressure reduction functions in a single compact assembly, making it ideal for natural gas, propane, air, nitrogen, and other non-corrosive gas systems.
The 67DFR-25 features a built-in 40-micron filter element (sintered polyethylene or metal mesh) that removes particulate contaminants from the gas stream, protecting downstream equipment and ensuring reliable operation. The filter element is replaceable and includes a differential pressure indicator for maintenance scheduling. This regulator delivers an outlet pressure range of 3 to 60 psig (0.2 to 4.1 bar) with a maximum inlet pressure of 300 psig (20.7 bar).
Key features include an internal relief valve with a soft seat for reliable shutoff with no discernible leakage, ensuring system safety. The temperature capability ranges from -29°C to 66°C (-20°F to 150°F), with optional Viton seals available for extended temperature service. The 67DFR-25 is commonly used in compressor post-treatment, instrument air systems, gas equipment, process control, building facilities, and OEM applications. Its compact design, easy maintenance, and reliable performance make it a preferred choice for commercial and industrial gas regulation needs.
