Specification

Green gas with built in lubrication

ASG ULTRAIR green power gas is the brand’s popular all round green gas, now with added lubricating silicone. Delivering around 135 PSI at 25C, it keeps your gas blowback pistols and rifles running reliably, while the silicone conditions the seals and internals with every shot for smoother long term operation.

A versatile all year choice

This 135 PSI rating makes it a genuine all rounder, performing best in spring, summer and early autumn. It is recommended for all blowback pistols and rifles, though it is not suited to Tokyo Marui or other ABS bodied guns that expect lower pressures. If you prefer a gas without silicone, the orange and red ULTRAIR options are silicone free.

Built for easy filling

The 570ml can holds around 520ml of liquid gas, roughly 270g, and uses a durable metal nozzle for quick, low waste magazine filling. It is a dependable, everyday choice to keep your loadout topped up all season.

Store it safely

The gas is extremely flammable, so keep it away from heat and direct sunlight and use it only outdoors or in a well ventilated area. Grab a can alongside your ammo in our BBs, gas and batteries range.

Frequently asked questions

What does the added silicone do?

The silicone lubricates the seals and internal moving parts of your gas gun with every shot, helping keep it running smoothly. Note it may affect hop-up performance in some setups.

How is this different from plain ULTRAIR power gas?

It is the same 135 PSI all round green gas, but with lubricating silicone added. Players who prefer no silicone often choose the plain, orange or red versions instead.

When should I use this gas?

At around 135 PSI it is a versatile all year gas, at its best in spring, summer and early autumn. For colder months, a higher pressure orange or red gas may perform better.

Can I use it in a Tokyo Marui pistol?

It is not recommended for Tokyo Marui or other ABS bodied guns, which are built for lower pressures. It suits metal slide blowback pistols and rifles.

Do I need to be 18 to buy it?

Yes, airsoft propellant gas is sold to customers aged 18 or over. UKARA is not needed for gas, only proof of age.
