The Air Pump is a block that can be purchased from the Merman for 1  Gold Coin. It can be placed next to an Air Tube Anchor, and as long as the player is near it, it will grant the player unlimited oxygen so long as they are within range of their Air Tube, wearing an Air Helmet, and their Air Pump is above water level.
