Frequently Asked Questions

What is the maximum operating depth of this product?

This product is suitable for use in waters up to 5 meters deep. It may be used at depths of up to 30 meters—but only as an emergency backup air source by certified divers.

How long does a full tank last?

Breathing time varies depending on depth, activity level, and breathing rate. On average, 0.5L tanks provide approximately 6–10 minutes of air at shallow depths. 1L tanks offer around 15–20 minutes, while 2L tanks may last 30–35 minutes.

Always monitor your pressure gauge during use. If the pressure gauge shows less than 2 MPa, return to the surface and refill before diving again.

Is certification required to use this product?

While certification is not required for shallow use, it is strongly recommended that all users receive proper instruction and certification from an accredited diving training agency. Improper use may lead to serious injury or death.

Can I use this product in cold water?

This product is designed for use in waters with temperatures above 10°C (50°F). Do not use in colder conditions.

Can I travel with this product?

Yes. Due to high-pressure regulations, cylinders must be empty and detached from the respirator when traveling by air. Always check with your airline’s policy beforehand.

What kind of air can I fill the tank with?

Only fill this tank with compressed air that meets human respiratory standards (EN12021). Do not use oxygen or other gases, as they may damage the internal system and pose safety risks.

What other precautions should I take before diving?

Before each dive, inspect the tank for any signs of damage or leaks and confirm it is fully pressurized. Do not use the product if it appears damaged or malfunctioning.

Never dive alone. Always dive with a partner to ensure safe operation.

Users over the age of 60 must obtain medical clearance from a doctor prior to use. This product is not suitable for pregnant individuals or those with medical conditions that make diving unsafe.

How often does the tank need servicing?

Have the product serviced annually by a professional. The gas cylinder requires a hydrostatic test every 5 years and should undergo visual inspection at least once a year.
