NB-45 Nitrogen Booster
Boost Lower Pressure Nitrogen Bottles to High Pressure Nitrogen Bottles
Powered by Shop Air or via Optional Nitrogen Bottle

PN: NB-45 - Without Calibrated Gauges and Certificate
PN: NB-45-Cal - With Calibrated Gauges and Certificate


The NB-45 pneumatic nitrogen booster provides the capability of boosting the remaining lower pressure nitrogen from supply bottles to the required pressure, up to 4,500 psi.

The nitrogen booster is driven by compressed air or nitrogen. It cycles automatically to boost low-pressure nitrogen to high pressure.

Gas bottles only supply enough gas until the system equalizes. Sometimes there may be 1000 psig of unused gas. Don't give back the product you have already paid for. By using our nitrogen booster, nitrogen bottles can now be pumped down to 200 psig. Cost savings on gas pays for the booster. Nitrogen can be transferred to another low-pressure bottle or directly into the aircraft. The unit is designed to be mounted on a wall, bench or on a portable bottle cart, so it can be taken to the aircraft. Operates by shop air or an optional nitrogen drive, cycling automatically to boost low-pressure nitrogen to high pressure. The regulator on inlet gas is required, at 3000 psig maximum pressure.


  • Lightweight - The NB-45 weighs only 23 pounds.
  • No inlet air valve, air regulator, or air lubricator required.
  • Totally sparkless operation.
  • Polymeric seals for long unit life and high efficiency.
  • Impossible for compressed air to contaminate nitrogen due to twin rod seals with vent between to atmosphere.
  • Quick disconnect allows you to power the unit by shop air or by the low-pressure nitrogen supply bottle.
  • Output rating: Adjustable from 500 to 4500 psi.
  • Nitrogen booster ratio: 45 to 1
  • Pumps donor bottle down to 200 psig
  • Can be mounted on bottle cart or work bench
  • Does not include regulators or adapters.

Top NB-45 Benefits

  • Less man-hours needed to set up and perform a service.
  • Less nitrogen inventory required to perform the same job as a cascade system.
  • Completely portable.

CGSE and the entire team was very helpful. They understood my need for on-time delivery so I could take it to Africa on my scheduled flight. They beat my deadline by 2 days. I will buy again from CGSE.
We are currently using this at our MRO hangar here in the ICT. This is a great machine and we are highly satisfied with the unit and the company we purchased it from as well as our sales rep. You guys have supported us with so much equipment that we need in order to keep all our hangar's project in-house. Again, Thank you!!
