I understand and am fully aware that there are many inherent risks and hazards associated with the operation of high-pressure gas booster pumps, including but not limited to: high pressure hazards – failure of hoses, fittings or the pump body can lead to catastrophic mechanical failure and high-velocity projectiles; oxygen hazards – handling oxygen or nitrox involves a high risk of fire, rapid combustion or explosion; gas toxicity – improper blending or contamination of breathing gases can lead to hyperoxia, hypoxia, hypercapnia, narcosis or decompression sickness; and physical injury – serious injury or death resulting from explosion, fire or mechanical impact. I fully understand and accept that, by using the Product, I may be seriously injured or killed, even if I do nothing wrong. I represent and warrant that I am a certified scuba diver or technician with specialized training in gas blending and handling of high-pressure gases. I have read and understand the manufacturer’s operating instructions and all safety protocols. I understand that any unauthorized modifications, use of non-original parts, or failure to follow service intervals voids any applicable warranties and significantly increases the risk of catastrophic failure. I voluntarily release, discharge, waive and relinquish any and all actions, claims or causes of action for injuries, damages or death arising out of my purchase, use or misuse of the Product based upon any negligent act or omission of the Released Parties, nor any of their officers, directors, instructors, agents, employees, contractors or assigns including, but not limited to, the design, materials, assembly, performance, warnings, instructions for use or operation of the Product.

USUN GBT 15/40-OL Booster Pump: The Ultimate Scavenger

Helium and oxygen are expensive. Leaving a few hundred psi in your storage banks because your current pump can't pull it out hurts your wallet. The USUN GBT 15/40-OL solves this problem. This double-action booster is built specifically to scavenge your supply gas down to approximately 100 psi (6.9 bar). By pulling your supply cylinders lower than standard pumps, this unit ensures you use nearly every cubic foot of gas you buy.

Critical Inlet Management 

This pump operates with high efficiency, but it requires specific input management. It needs a minimum inlet pressure of 7 bar (approx. 101 psi) to function, but it has a strict maximum inlet pressure of 45 bar (approx. 652 psi). You must regulate your supply gas down to 45 bar or lower before feeding it into the booster. Following this protocol is essential for the safety and longevity of the equipment.

High-Pressure Output 

Once the gas is in the system, the booster delivers impressive results. With a 40:1 pressure ratio, it achieves a maximum outlet pressure of 330 bar (approx. 4,786 psi). This makes it fully capable of filling high-pressure steel cylinders for deep technical dives without breaking a sweat.

Air-Driven Safety 

Safety in the fill station is paramount. This unit is air-driven, requiring no electrical connections, which eliminates heat, flame, or spark risks. Being oxygen cleaned from the factory, it is ready for blending service immediately. The seal system is designed for a long working life and requires no airline lubrication, keeping your gas path clean and reducing maintenance.

Drive Gas Requirements 

While the manufacturer lists a high drive gas requirement of 28 cfm for rapid cycling (60-70 cycles per minute), we find that running it slower is safer and generates significantly less heat. Our clients operate this booster successfully using compressors delivering 12 cfm to 16 cfm. Note: We highly recommend installing a dryer and filter between your shop compressor and the booster to protect the drive mechanism.
