Aqualung Airsource 3 BCD Inflator and Alternate Regulator
Combine BCD inflation and alternate-air capability with the Aqualung Airsource 3. Its balanced second stage sits at the inflator position, while the Trim Grip gives you a separate exhaust control along the hose. It suits divers who want this combined layout and are trained in its donation procedure.
Features and benefits
- Balanced breathing mechanism. The pneumatically balanced second stage supports consistent inhalation response in a compatible regulator system.
- Inflation and alternate air together. Keep the BCD inflator and alternate breathing source at the same accessible point on the corrugated hose.
- Trim Grip exhaust control. Release air through the Trim Grip control without taking the second stage out of your mouth.
- Flexible hose layout. The lightweight Flexi-hose bends readily, with clips and recesses for arranging the medium-pressure supply hose.
- Detachable for packing. The bayonet connection at the Trim Grip lets the breathing unit separate from the BCD for transport with your regulator.
- Comfo-Bite mouthpiece. The palate bridge helps support the second stage without a tight bite.
Setup and compatibility
Check BCD attachment and medium-pressure hose compatibility before fitting. A qualified technician should configure and check the complete system. Use the alternate-air procedure appropriate to a combined inflator and your training.
