Rhythm Oxygen Regulators are engineered to deliver precise, dependable oxygen flow in clinical, homecare, and portable settings. Available in both standard and compact mini sizes, these regulators provide the same high performance while offering flexibility for stationary systems or portable oxygen bags. Built with an aluminum body and brass core, each regulator is designed for durability, safety, and ease of use.
A 1.5” easy-to-read pressure gauge and clear flow-rate window allow caregivers and patients to monitor oxygen delivery at a glance, while the single selector knob ensures smooth, accurate adjustments. An internal pressure relief valve enhances safety, and all models comply with CGA standards and are UL approved for trusted performance.
