Oxygen Pressure Regulators

The Life Support Products series of all-brass body oxygen pressure regulators provides enhanced safety features and a greater number of flow selections for the EMS professional. The uni-body construction is designed to strengthen the regulator, minimize potential leak paths, and prevent breakage of the yoke cylinder connection assembly. For additional safety, inlet filters provide gas filtration down to 20 microns. Standard LSP regulators have a 5-year warranty.

LSP regulators offer 12 flow positions … more flow selections than ever before. Equipped with up to two DISS check valves, LSP regulators provide regulated pressure and flow for the operation of two demand valves, or one demand valve and one aspirator, or any pneumatically-powered ventilator. A DISS or hose barb adjustable flow outlet permits attachment of a disposable mask, cannula, or bag mask device. All three outlet configurations may be operated simultaneously.

The Rhino™ oxygen regulator is virtually unbreakable. This oxygen pressure regulator features an all-brass unibody construction designed to strengthen the regulator, prevent yoke damage and regulator leakage, and protect the flow selector knob from accidental adjustment. The Rhino regulator also has a unique integrated aluminum shroud and lens cover that shelters the gauge from breakage and contamination, and is available in a choice of five colors.

A 20 micron sintered bronze gas inlet filter provides gas filtration and additional protection against contamination. Rhino regulators are available with up to two male DISS oxygen check valves and different flow ranges delivered through a hose barb outlet. The Rhino regulator has a 10-year warranty.
