FAQs

As a trusted supplier of gas, we frequently get asked questions about gas safety, the difference between butane and propane, as well as the best uses for our gas products. In this blog, we’ll be answering our most common FAQs.

Cylinder size should be selected based on expected air consumption, required pressure, and how frequently the air supply will be used. Larger cylinders reduce the need for frequent replacements, while smaller cylinders offer greater portability for site work. Adams Gas provides compressed air cylinders in sizes suited to different operational needs.

Compressed air cylinders are commonly used for pressure testing, pneumatic tool operation, tyre inflation support, leak detection, and general workshop tasks where a controlled air supply is needed. Adams Gas supplies compressed air cylinders suitable for trade and industrial environments.

A compressed air gas cylinder is typically chosen when portability, low noise, or temporary air supply is required. It is also suitable where installing or operating a compressor is impractical. Adams Gas supplies compressed air gas cylinders designed to support these professional use cases.
