FAQ

Common Questions

Everything you need to know before your first dive with DEDEPU.

How long does the air last in a mini scuba tank?
Air duration varies by lung size and depth. The S3000 (0.5L) provides approximately 3–5 minutes of continuous breathing at surface, while the D600 (2.3L) extends this to 15–25 minutes.
Are DEDEPU tanks safe for beginners?
Yes. All DEDEPU tanks include a certified pressure relief valve and burst-resistant construction. We recommend reading the safety guidelines and never diving beyond your certification level.
What certification do your tanks have?
All DEDEPU tanks are CE and ISO 7866 certified. They meet EU, US, and international recreational diving equipment standards. Certification documents are included with each purchase.
How do I refill a mini scuba tank?
DEDEPU tanks are compatible with standard SCUBA diving air fill stations. Most dive shops, dive clubs, and some surf shops offer air refills. You can also use the DEDEPU Electric Air Compressor for home refills.
Can I travel with a mini scuba tank?
Empty tanks can be transported in checked luggage on most airlines. Always check with your airline before travel. Never transport a pressurized tank on an aircraft.
What is the maximum depth rating?
DEDEPU tanks are depth-rated to 30 meters (98 feet), suitable for recreational scuba diving. Do not exceed this depth as pressure and air consumption increase significantly.
How often should I have my tank inspected?
We recommend an annual visual inspection and a hydrostatic test every 3 years. Tanks should be serviced by a qualified dive equipment technician if damaged or after any impact.
Do you ship internationally?
Yes. We ship to over 50 countries worldwide. Standard shipping is free on orders over $99. Express shipping options are available at checkout with delivery times of 3–7 business days.
