Helium Fill – Per Cubic Foot

This service provides helium fills, billed per cubic foot of helium added. Pricing is based solely on the amount of helium introduced into the cylinder, allowing for precise cost control and accurate blending for technical and mixed-gas diving applications.

Helium is added according to the requested blend and verified using appropriate gas analysis procedures. This service is intended for divers requiring helium as part of trimix or heliox blends and is commonly used for technical training, decompression planning, and advanced diving operations.

Pricing Structure

• Helium is charged per cubic foot

• Total cost is determined by:

  • Cylinder size

  • Starting pressure and existing gas composition

  • Target final mix and working pressure

Final pricing reflects the actual volume of helium added, not the finished cylinder volume.

Service Notes

• Partial pressure blending only

• Cylinder must be clean and approved for the intended gas mixture

• Valve and cylinder must be compatible with helium service

• Gas analysis and labeling are required prior to release

Additional charges may apply if oxygen service, cleaning, or valve work is required before filling.

Important Information

• Customer must specify the desired final gas mix

• Cylinders not suitable for helium service may be refused

• All gas fills are final sale and non-refundable once dispensed

Recommended For

• Trimix and heliox divers

• Technical and advanced training programs

• Decompression and staged gas planning

• Divers requiring precise control over helium costs

This per-cubic-foot helium fill service offers transparent pricing and accurate blending for divers who require high-quality, standards-based mixed gas fills.
