Single tank / Air

Air filling for compressed air cylinders, such as scuba tanks or airgun reservoirs.

We only fill standardized steel and aluminum cylinders that are EN/CE marked and equipped with DIN or Yoke valves. The maximum cylinder volume is 20 liters.

We do not fill composite cylinders.

Please ensure that your cylinder’s hydrostatic test stamp is valid. In Finland, the pressure test certification for compressed air cylinders is valid for 10 years.

We aim to fill cylinders while you wait; however, during busy periods—especially in the afternoon or early evening—we may only be able to guarantee that cylinders dropped off will be ready for pickup the following day.

To ensure your future dives go smoothly and you have sufficient air, please check the cylinder pressure when picking up your tank. A pressure gauge is available for your use at the compressor station.

NOTE: If your cylinder is completely empty, or if we are filling a brand-new, empty cylinder, we will allocate the necessary time for the process. We first fill the cylinder, allow it to cool (letting the pressure stabilize to the ambient temperature), and then add more air—a process known as "topping up."
