Rating: one less hose
Reviewer: Ken W.
Great alternate for octo. The only difference is you breathe off the spare(due to the short hose) and you share your main. Works great as an inflator and as a spare air

This is a nice addition to my BC. I am glad I ordered it with my BC. It came in handy one afternoon while servicing a boat with my partner. He ran out of air and just had about 5 minutes worth of work to finish up. So, I took the duo air source and he took my regulator. The duo air worked like a champ, it was hard to tell that this was not a typical regulator. The duo air source eliminates an extra hose dangling off me, just one less thing that was not in the way.

A great way to "clean up" your regulator set-up, eliminate one hose, and all at a very affordable price. It was very easy to install and works great! My son loves it!....Reg Harper

Questions and Answers for TUSA Duo-Air:

  • Peter:

    Hello there. I bought the Tusa Duo Air for the Tusa BCJ8000C. I have a serious question. Do I install it my self? OR do I need to get someone do it for me. I knowticed that there will be some cutting and stuff of the straps that hold it very tight. The duo air came with 2 straps to tie it back to the inflator unit. Also i knowticed that the inflator unit has cable on the left side going through it and the duo air has the cable needing to go on the right side of the inflator tube.That looks like it will be only cosmetic unless i have it all setup wrong.

    If you have any question or concern about the installation it''s always best to ask a qualified technician to help. The Tusa Duo Air is designed to be quite simple to install. It will install in the exact reverse order the power inflator removes from the bcd. The Tie Wraps that come with the unit secure the corrugated hose between the raised ridges on the barrel of the Duo Air to not only create a good seal but a secure connection. the internal cable is held in place with the use of the roll pin that slides through the duo air unit as well as the swedged loop in the cable that operates the shoulder dump.

IR-3 TUSA Duo-Air

The IR-3 Duo-Air is a downstream safe-second 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

Demand System
* The demand system is designed to signi? cantly reduce rubbing resistance of moving parts and air resistance. The result is smoother and more natural valve opening/closing.

Light weight housing
* The second stage main unit is smaller and lighter to reduce water resistance during diving, thus reducing the load on the face during use. The main body materials
are super-tough nylon (heat pliable polyamide resin) reinforced with glass ? ber for
outstanding hardness and shock resistance. The materials also offer superior tensile
strength, dimensional stability, heat resistance, weather resistance and chemical resistance.

Intake resistance
* The second stage includes a director to forcibly guide air from the demand valve.
That prevents free ? ow while signi? cantly lessening intake resistance. The result is

one of the lightest intake resistance values in the industry compared with products
from other companies.

New mouthpiece
The new mouthpiece, developed on the basis of ergonomic engineering, further
enhances the comfort of bite, ? t, and stability. Even with a light bite, a high level of
stability is achieved, so there is no fatigue from long periods of usage.
