Nitrogen tanks for paintball guns

 Nitrogen tanks for paintball guns: Nitrogen tanks or HPA (High Pressure Air) tanks are the modern adaption CO2 tanks for paintball tanks.In this post we will discuss in detail about the importance of a HPA tank , how to choose the best one and how to use them.A paintball gun uses HPA or Nitrogen tanks for pressure to propel and cycle the paintball. It is of the iportant widget for your Paintball game, as it determines how far you can fire. To a great extend an accuracy of a paintball gun lie on Nitrogen or HPA tanks.

Different types of Paintball Tanks

There are mainly three different kind of pressure tanks avaialble in the market. The need for buying HPA tanks completely depends on your purpose. CO2 tanks are completly good for beginer level players. In olden days , most of the paintball markers use CO2 tanks for firing. CO2 is less denser and need less PSI(Pounds Per Square Inch) when compared to HPA/Nitrogen tanks. Similarly Nitrogen or HPA tanks are more costlier than CO2 tanks. You might be thinking then why you should choose a HPA tank over CO2. Let me explain that it detail.

HPA or CO2 tank will have compressed air which is stored in the form liquid. It is simialr to LPG (Liquified Petroluem Gas), but dont worry CO2/HPA are safe to use. Markers use this pressure inside the tank to push to paintball far away from your gun. Most of the guns were using CO2 tanks, but then its performance started to deminish on sunny days. As the outside tenperature increases(Summer) , the CO2 which is store in the form liquid will start to change back to gas state. This reduces the pressure applied on the paintball and gradually the distance it travel reduces.  In a way it affected the accurcy of most paintball players. This created the need for an alterntive for paintaball guns.

Nitrogen which is abundent in our atmoshpere is another best solution for this issue.Eventhough Nitrogen is abundent , it is more costlier to use. Thus due to this reason, HPA tanks use other gases with Nitrogen to improve the pressure and make it economical. Nitrogen/HPA tanks are little more heavier when compared to CO2 tanks.

If you are confused on which one to choose between CO2 tank or HPA tanks, the below comparison will help you to make a judgement for you.

Co2 Tanks


  1. Low cost
  2. Weather will impact your accuracy.
  3. Widely available in the market.
  4. Refills are widely avaiable


  1. Need to empty a tank before refilling

HPA /Nitrogen Tanks


  1. Cost from Mid to High
  2. Not impacted by weather
  3. Compatible with all Paintball markers
  4. Can be refilled in between a game.


  1. Special shops required for refill

In a nutshell, HPA tanks are the best option for those who care for improving accuracy and speed of your marker. HPA /Nitrogen tanks uses PSI ranging between 3000 – 4500 which is very high and safe when compared to CO2 tanks.
