Product Overview
Altitude compensating pressure regulators are designed to increase system regulator outlet pressure at higher altitudes and conversely reduce pressure as altitude decreases. This action effectively reduces oxygen at lower altitudes while maintaining required minimums, thus conserving oxygen. Specified flow requirements are achieved typically through the use of a .016 nominal diameter orifice, positioned either in the constant flow mask outlet or the mask connector assembly.
