ASG ULTRAIR Power gas 570 ml - 135PSI - no silicone

A gas manufactured by ASG that operates over a wide temperature range and has enough power (135PSI) to also be used in metal-slide guns. The bottle has a special aluminum filling valve that is more durable than the traditional plastic one. A tight connection with the refillable magazine that reduces gas waste.

The gas does not contain added silicone, which helps to keep the gas supply more consistent. However, this should be taken into account when servicing the gun and the necessary parts and seals should be lubricated with silicone.
