The Air 2 is designed for intuitive use, combining inflation/deflation controls with an alternate air source function.
3.1. เงินเฟ้อและเงินฝืด
- อัตราเงินเฟ้อ : Press the red button (inflator button) to add air to your BCD. The air-balanced power inflator valve ensures a steady stream of air.
- ภาวะเงินฝืด: Press the gray button (deflator button) to release air from your BCD. The large purge button is designed for easy operation, even with thick gloves.
3.2. Alternate Air Source Function
In an emergency out-of-air situation, the Air 2 serves as a reliable alternate air source. Its integrated design means you always know where to locate your backup regulator.
- การหายใจ: The Air 2 features a comfortable mouthpiece, allowing it to be used for breathing directly.
- Dive/Pre-Dive Switch: The Air 2 includes a fixed Venturi Initiated Vacuum Assist (VIVA) Flow Vane with a dive/pre-dive switch. This switch allows you to adjust the regulator mechanism to prevent free-flow at the surface or in strong currents, and to optimize breathing performance during a dive.

4. การบำรุงรักษา
Regular maintenance is essential to ensure the safety and performance of your SCUBAPRO Air 2 regulator.
- การล้าง: After each dive, thoroughly rinse the Air 2 with fresh water while it is still pressurized to prevent water ingress into the internal components. Once rinsed, depress the purge button briefly to clear any water from the mouthpiece.
- การอบแห้ง: Allow the regulator to air dry completely in a shaded, well-ventilated area. Avoid direct sunlight or excessive heat.
- พื้นที่จัดเก็บ: Store the Air 2 in a cool, dry place, away from direct sunlight, chemicals, and extreme temperatures.
- การบริการระดับมืออาชีพ: It is recommended to have your Air 2 regulator professionally serviced by an authorized SCUBAPRO technician annually or after every 100 dives, whichever comes first. This ensures all internal components are inspected, cleaned, and replaced as necessary.

5 การแก้ไขปัญหา
If you encounter issues with your Air 2 regulator, consider the following common troubleshooting steps. For persistent problems, contact an authorized service center.
- Free-Flowing Regulator: If the regulator free-flows, ensure the dive/pre-dive switch is in the 'pre-dive' position when not actively breathing. Check for debris in the mouthpiece or diaphragm.
- Hard Breathing: Verify that the low-pressure hose is securely connected and that your tank has sufficient air pressure. Ensure the dive/pre-dive switch is in the 'dive' position.
- การรั่วไหล: Inspect all hose connections for tightness. Check O-rings for damage or displacement. If a leak persists, professional inspection is required.
- Inflator Malfunction: Ensure the BCD inflator mechanism is clean and free of sand or salt crystals. Check the quick-disconnect fitting for proper engagement.
