Typical filling times
Typical trailers hold 3,000β6,000 NmΒ³ of helium.
Fast, high-capacity filling station: 30β90 minutes
Standard industrial filling: 2β4 hours
Small compressor / limited supply: 6+ hours
Tube trailers are commonly filled to 200β300 bar (3,000β4,350 psi)
The last 20β30% of pressure takes disproportionately longer.
