SW Series Full 316 Stainless Steel Filter Regulators (FR Units)

Features & Key Specifications

Features & Key Specifications of Our Stainless Steel FR Units:

Complete 316 Stainless Steel Construction:

This is a full stainless steel unit. The main bodies of the filter and regulator, as well as the filter bowl, are all constructed from SS316, providing total protection against corrosion and physical impact.

High-Pressure Operation (0-1.6 MPa):

Designed for demanding industrial systems, this FR unit operates reliably across a wide pressure range, from zero pressure up to a maximum of 1.6 MPa (16 bar / 232 PSI).

Essential 2-Stage Air Treatment:

This integrated unit combines the two most critical functions for any pneumatic system:

Filter: Removes solid particulates (25μm standard, 5μm optional) and separates condensed water.

Regulator: Provides stable, adjustable output pressure to protect downstream components.

High Flow, Lube-Free Air:

Designed for modern "lube-for-life" pneumatic systems, this unit delivers high volumes of clean, regulated air without any oil contamination, making it perfect for sensitive applications.

Designed for Sanitary & Washdown Applications:

The full stainless steel design is perfect for food grade and hygienic applications. It can be thoroughly cleaned and sanitized without risk of degradation or rust.

Global Thread Compatibility:

To meet worldwide requirements, we offer three standard thread types: NPT for North America, BSPP (G), and BSPT (P), in sizes from 1/4" to 1".

Application Fields

The Workhorse for Clean, Regulated Air in Harsh Environments:

Food & Beverage Processing: The standard for point-of-use air preparation for valves and cylinders in high-washdown zones.

Pharmaceutical & Biotech: Providing clean, oil-free air for process automation in sanitary and sterile environments.

Chemical Plants: A robust, corrosion-resistant solution for instrument air and general pneumatic control.

Marine & Offshore: The definitive choice for applications with constant exposure to saltwater spray.

Paint & Finishing: Delivering clean, moisture-free air that is critical for high-quality surface finishing.

Technical & Selection Guide

Why Choose an SW Series (FR) Unit?

The Most Common Requirement: Most modern pneumatic systems do not require in-line lubrication. A filter regulator (FR unit) provides the two essential functions—filtration and regulation—that nearly every application needs.

Total Corrosion Resistance: A full SS316 unit ensures every component, not just the bowl, can withstand corrosive chemicals and washdowns, guaranteeing a longer service life than standard or partially stainless units.

Compact & Efficient: Combining the filter and regulator into a single body saves space and reduces potential leak points compared to using two separate components.

FAQ

Frequently Asked questions

Q: What is a filter regulator?

A: A filter regulator, or FR unit, is a single pneumatic component that combines a particulate/water filter and a pressure regulator into one body. It is the most common and essential type of air preparation unit.

Q: What is the maximum pressure this FR unit can handle?

A: The maximum working pressure for the SW series is 1.6 MPa, which is equivalent to 16 bar or approximately 232 PSI.

Q: When would I need an FRL (with a lubricator) instead of this FR unit?

A: You would only need an FRL unit (like our SC Series) if you are powering older pneumatic tools or air motors that specifically require a continuous mist of oil lubrication to function.

Q: Does this unit remove water?

A: Yes, the filter component is designed to remove liquid water and solid particulates from the compressed air line through centrifugal action and the filter element.
