• D2, E2 and G Size Whether you need to inflate 145 or 600 balloons*, there's a size to suit. Our high-pressure cylinders are compatible with 200 bar inlet pressure rated regulators with a Type 10 fitting, such as BOC Balloon Gas Regulator Right Angle or BOC Balloon Gas Regulator Vertical
• *The number of balloons to fill is an approximate indication only, based on a 28cm (11') diameter balloon size. The number of balloons can be impacted by user behaviour, air temperature & other factors. BOC cylinders must only be returned to BOC for safe filling/refill.
