TUSA IR-3 Duo-Air Alternate Inflation Regulator

A downstream backup regulator that also provides you with easy to operate buoyancy control.

The IR-3 is positioned at the end of the buoyancy compensator hose, the ideal location for quick, efficient use. Because you use it as your power inflator, you always know where it's located (that's a priceless advantage in an emergency). Plus, the IR-3 cuts down on hose clutter because the same hose is used to supply both the power inflator and the backup regulator. The regulator features a dependable downstream demand valve mechanism.


  • Combination of octopus regulator and power inflator
  • Classic downstream regulator valve
  • Air balanced power inflator valve
  • Single hose configuration
  • Nitrox compatible to 40%
  • Inflator integrated secondary air source
  • Increased safety in out of air emergencies
  • Self flushing mechanism
  • One button purge function
