Pressure & Flow Regulators
Today’s high performance ventilators and resuscitators need high performance regulators to optimize their output capabilities. That’s why our O-Two Oxygen Regulators are the perfect choice to meet the needs of the respiratory impaired patient or those in respiratory arrest. The all brass (or aluminum body/brass core) construction of these high quality regulators improves product safety by reducing the risk of exacerbating a regulator fire should it occur.
With an optional oxygen therapy flow rate range of 0-15 L/min or 0-25 L/min you can choose the range that most suits the needs of your patient in respiratory distress who requires oxygen therapy. For powering oxygen equipment, different configurations of pressure outlets are available. Input connections of either nut and stem or pin indexed yoke are available as well as regulator for Entonox® analgesic gas.
By providing consistent output pressure and flow, the O-Two range of Oxygen Regulators ensures the maximum operating time on any cylinder. Built for the demands of the pre-hospital and in-hospital markets, the O-Two Regulator series provide unbeatable quality and performance.
Oxygen Regulators – Flow Therapy Only

High-Performance Regulator for Oxygen Therapy
When you need to provide oxygen therapy, the O-Two Adjustable Oxygen Therapy Regulator provides quality manufacturing and performance. The “Aluminum Free” brass construction improves product safety by reducing the risk of exacerbating regulator fires should they occur. Where weight is a concern the aluminum body/brass core regulators provide the security of all brass construction.
With its offset gauge and small diameter body, these regulators are one of the smallest of their type. Ideal for all applications where adjustable oxygen therapy 0 – 25 lpm flow rates are to be provided.
It is unbeatable for quality, size and performance.
Features
- Low profile contents gauge
- Slim overall profile
- All brass or aluminum body/brass core construction
