Questions and Answers for Sherwood 45 Cubic Foot Aluminum Scuba Tank:

  • Darren:

    Gday there, It is possible to sent the tank to Australia and if so, how much would it cost. Kind regards Dazz and wendy

    Bob  (Certified Scuba Instructor at

    We can send them but unfortunately our cylinders aren't stamped with the necessary markings to get airfills in Australia.

  • nan:

    I just need to check the liner of my swimming pool occasionally, and I know nothing about diving. Would this work, and what other equipment would I need?

    Darrick  (Certified Scuba Instructor at

    Hello Nan, first if you are going to you this tank to breath off of you will need to get a scuba diving certified. You will not be able to fill the tank if you are not certified.

  • Dan:

    I am getting a precharged air rifle that can be charged via scuba tanks. Will I be able to get it filled without a divers certificate? Do the dive shops use dry air, moisture can cause problems with air guns?

    Darrick  (Certified Scuba Instructor at

    Hello Dan, if you take this tank to be filled at your local dive shop they will be asking for a dive certificate card. Now you can try and talk with your dive shop that you will be using this for an air rifle. But that would be up to the dive shop or not. Also this is compressed air is a dry air.

  • Raul:

    Can I use the scuba tanks for paintball tanks refills?

  • Brady:

    How long does it last when full

    Darrick  (Certified Scuba Instructor at

    Hello Brady, depends on your breathing rate and how deep you are. The deeper you are the more air you will use.

Aluminum Tanks
Aluminum tanks are cost efficient, long lasting, and readily available, which is why they are easily the most common scuba diving tanks in the world. Lighter than steel tanks, aluminum dive tanks are easier to transport and swim with, giving your shoulders and arms a break on long treks.

Because of their light weight, some aluminum tanks will begin to float at the end of a dive, once the oxygen supply is nearly depleted. To combat this, it's common to counter-weight an aluminum dive tank with approximately 4 pounds. However, 'Compact Neutral' aluminum tanks are made with thicker walls, which increase the weight and help to counteract the positive buoyancy problems at the end of a long dive.
