** A small scuba diving tank would do the job, you can get 3L ones.

They hold air pressures up to 3000psi or about 200 atmospheres - so you get
600L of air.

Only problem is recharging one.

Been Googling a bit, and it seems PCP Air Rifles commonly utilise Scuba
tanks, and you can actually get hand pumps that will provide up to 250 bar.
If you are young and fit enough.
