Disclaimer on High Pressure Air (HPA) Systems:
HPA Tanks are a safe and effective source of power though there are some precautions you must follow. Please follow these proper precautions when using HPA systems:
  • NEVER put oil in the fill valve of the tank, or else the tank can combust on refill and serious injury can occur. Lubrication is not necessary in HPA systems.
  • ONLY allow properly trained professionals to fill your HPA tank.
  • ALWAYS double check your Regulator pressure. Never raise the regulated pressure above 120 PSI.
  • Make sure to have your tank Hydro-Tested when necessary (Usually 3-5 years from date marked on tank, depending on make and model).
  • Be sure to properly transport your HPA tank. Store in a safe, secured place when in a vehicle, and be sure to stow in a bag or tank cover when in use. Avoid dropping the tank on hard surfaces as this can seriously damage the tank and lead to failure.
  • Always turn off the tank and bleed the air line when you are done. This will ensure a longer tank and system lifespan.

"Better than a fusion engine, worse than an f2/inferno gen 2 with a gate titan. Consider if you need a mechanical engine. Otherwise go for the inferno or f2
