The Harris Model 330-350-540 Oxygen Regulator is a premium industrial gas control device engineered specifically for the rigorous demands of gaseous withdrawal from liquid cylinders. In the world of industrial gas distribution, consistency and reliability are paramount. This regulator addresses those needs with a robust design that ensures steady flow and precise pressure maintenance, even when dealing with the high-volume output typical of liquid oxygen setups.
At the heart of the Harris 330 series is a large 2-3/4 inch stainless steel diaphragm. Unlike neoprene diaphragms that can degrade or fluctuate in extreme temperatures, stainless steel provides exceptional longevity and maintains accurate pressure regulation over a long service life. The body is constructed from forged brass, offering substantial resistance to physical damage and corrosion in harsh shop environments. A chrome-plated bonnet adds an extra layer of protection and professional aesthetic, while the brass adjusting screw allows for smooth, low-torque pressure adjustments.
One of the standout features of this regulator is its one-piece PTFE (Teflon) encapsulated seat design. This advanced engineering places the seat inside a protective capsule with an internal filter. This configuration drastically reduces the risk of seat failure caused by particulate contamination—a common issue in industrial gas lines. By filtering out debris before it reaches the sealing surface, the Harris 330 ensures a leak-free seal and reliable performance shift after shift.
Safety is non-negotiable when handling oxygen. The Harris 330-350-540 is equipped with a self-seating internal high-pressure safety valve designed to vent excess pressure safely if a malfunction occurs. The unit fully conforms to CGA-E-4 standards for gas pressure regulators, giving safety officers and facility managers peace of mind. Whether you are supplying assist gas for laser cutting, running a heavy-duty manifold, or managing a central oxygen supply, this regulator delivers the performance and safety required for professional operations.
