Variable capacity tank BO

Perfect surfaces – and what you see here is only the outside! The inside will blow your mind!

The variable capacity tank BO is often described as 'starter kit'. It is, however, also utilised by advanced users for small quantities. Its outstanding price-performance ratio and handy size have made it so popular that the ›BO‹ is now being used all over the world.

Thanks to its floating lid (accessory) the tank’s volume always adapts itself to the actual content and locks the tank up properly. The tanks have a strengthening rim. The flat base ensures high stability, characteristic of all Speidel tanks.
