Features

• 1.316L Stainless Steel Construction: Exceptional corrosion resistance for harsh chemical, marine, and offshore environments, conforming to NACE MR-0175 for sour gas applications

• 2.Combined Filter-Regulator Design: Integrates filtration and pressure regulation in one compact unit for efficient air preparation

• 3.Large Flow Capacity: Optimized internal geometry for high flow rates, reducing pressure drop across the unit

• 4.Dual Filtration Options: 40 micron stainless steel element as standard, with 5 micron option available for applications requiring finer filtration

• 5.Flexible Drain Options: Manual drain as standard, with optional auto-drain for continuous operation in unmanned installations

• 6.Pressure Relief Options: Non-relieving or self-relieving configurations to meet specific system requirements

• 7.Wide Temperature Range: Standard: -20°C to +80°C (-4°F to +176°F); low temperature version available for -50°C to +80°C (-58°F to +176°F) operation

• 8.Transparent Bowl: Polycarbonate bowl with protective metal guard for visual inspection of filter element condition and condensate levels

• 9.Integral Mounting Holes: Facilitates easy installation and secure mounting in any orientation

• 10.Rolling Diaphragm: Ensures precise pressure control and consistent performance over the entire operating range
