3003541 - Harris 3500 Series High Flow Nitrogen Regulator, 0-600 PSIG Delivery, CGA 580

Heavy-Duty High Flow Nitrogen Regulation

The Harris 3500-600-280 Nitrogen Regulator is a premium industrial-grade component designed for applications requiring high flow rates and precise pressure control. Engineered by Harris Products Group, a leader in gas distribution equipment, this regulator is part of the renowned 3500 series. It is specifically built to handle high-pressure cylinders up to 3000 PSIG while delivering a consistent output pressure ranging from 0 to 600 PSIG. This makes it an exceptional choice for demanding tasks such as HVAC pressure testing, nitrogen purging, and blanketing applications where reliability is non-negotiable.

Advanced Engineering and Design

At the core of this regulator is Harris's signature one-piece encapsulated seat design. This innovative feature includes an internal filter that protects the seating surface from particulate contamination, which is the leading cause of regulator failure. By preventing debris from entering the high-pressure seat area, the service life of the regulator is significantly extended. The unit also features a large 2-3/4" neoprene diaphragm. Unlike smaller diaphragms found in compact regulators, this substantial surface area allows for highly sensitive pressure adjustments and maintains stable delivery pressure even as the cylinder pressure decays.

Safety and Durability

Safety is paramount in high-pressure gas handling. The Harris 3500 regulator is equipped with a tamper-proof, self-seating internal safety valve (IRV). This valve is designed to vent excess pressure safely in the event of a malfunction, protecting both the user and downstream equipment. The construction is robust, featuring a forged brass body and bonnet. This all-brass construction ensures resistance to corrosion and withstands the physical abuse typical of industrial job sites, workshops, and field service environments. The ergonomic adjusting knob allows for smooth, low-torque pressure setting, reducing operator fatigue during repetitive adjustments.

Technical Specifications

This model comes equipped with a CGA 580 inlet connection, the standard for nitrogen cylinders in North America. The gauges are clear and easy to read, providing vital information on both cylinder contents and delivery pressure at a glance. Whether you are performing leak detection in refrigeration systems or managing process gases in manufacturing, the Harris 3500-600-280 provides the flow performance and rugged dependability required for professional results.
