Product Details：

Product Dimensions：

The FS-67CFR-362 is an integrated unit that combines a fine-mesh filter with a high-accuracy pressure regulator. The "CFR" designation indicates that it is a Filter Regulator with Internal Relief, which is a critical safety feature for protecting downstream equipment. The body is typically constructed from rugged aluminum, designed to withstand harsh industrial environments. It includes an internal cellulose or stainless steel filter element that removes moisture and solid particles from the compressed air supply, ensuring that sensitive internal components of connected instruments remain free from contaminants.

Product Parameters

The technical specifications for the FS-67CFR-362 configuration include:

Body Size and Connection Style: 1/4 inch NPT (National Pipe Thread).
Maximum Inlet Pressure: $250 \text{ psig}$ ( $17.2 \text{ bar}$ ).
Outlet Pressure Range: Typically configured for $0$ to $125 \text{ psig}$ ( $0$ to $8.6 \text{ bar}$ ), depending on the internal spring.
Filter Element: High-capacity $5\text{-micron}$ filter element.
Temperature Capabilities: Standard Nitrile (NBR) elastomers allow for operation between $-20^{\circ}\text{F}$ and $160^{\circ}\text{F}$ ( $-29^{\circ}\text{C}$ to $71^{\circ}\text{C}$ ).
Pressure Registration: Internal.
Relief Operation: Internal relief feature that allows excess downstream pressure to vent through the diaphragm.
Material Construction: Aluminum body with a stainless steel filter bowl and bolt.

Product Advantages

One of the primary advantages of the FS-67CFR-362 is its Compact and Lightweight Design, which allows it to be mounted directly onto control valves or instruments without requiring heavy support structures. The High Flow Capacity ensures that it can meet the air demands of modern high-performance positioners even during rapid valve movements.

The Internal Relief Valve is a significant safety benefit; it prevents downstream pressure from exceeding set limits in the event of a regulator failure, protecting expensive smart instruments. Furthermore, the Easy Maintenance design allows the filter element to be replaced or the bowl to be drained of moisture without removing the regulator from the piping, significantly reducing downtime during routine inspections.

Important Considerations and Precautions

When installing and maintaining the Fisher FS-67CFR-362, certain precautions are necessary for safe operation. First, ensure the Flow Direction matches the arrow cast onto the regulator body; reversed installation will prevent the unit from regulating correctly. Second, before performing any maintenance, such as draining the filter or replacing the element, the Inlet Pressure must be shut off and any trapped pressure must be safely vented.

Third, because this is an aluminum-bodied unit, it should be used in environments where the atmosphere is not excessively corrosive to aluminum. For offshore or highly acidic environments, a stainless steel version (67CFSR) should be considered instead. Finally, the Drain Valve at the bottom of the filter bowl should be opened periodically to remove accumulated water and oil, as excessive liquid buildup can bypass the filter and damage downstream electronics.

Product Applications

The FS-67CFR-362 is a staple in industries requiring precise pneumatic control.

Oil and Gas Production: Providing clean air to pneumatic actuators and control valve positioners on wellheads and processing platforms.
Chemical and Petrochemical: Regulating the air supply for sophisticated smart transducers and I/P (Current-to-Pressure) converters.
Power Generation: Used in turbine control systems and steam valve regulation where air quality is critical for long-term reliability.
Pulp and Paper: Controlling pneumatic instrumentation in high-vibration and humid environments.
General Industrial Automation: Acting as the primary air preparation unit for any pneumatic control loop requiring a stable $20\text{ psi}$ or $35\text{ psi}$ supply to instruments.
