30 % smaller than before and refillable, the new float 2.0 cylinder. the refillable float cylinder 2.0 is the power behind the new bca float 2.0 system. as with the rest of the system, the weight and size have been shaved down and is now 30 percent smaller. the cylinder still has the full pressure release of 3 000 psi of compressed air needed to activate the airbag. the float 2.0 cylinder is compatible with all float 2.0 backpacks, the float 17 speed and the float 27 speed.bca cartridges are reusable bottles and are reconditioned by bca. it gets refilled and also the sealing rings are renewed in the process. this makes the cylinder ‘like new’ again. bca affixes the ‘reworked’ sticker to the cylinders.
