In most cleanrooms, nitrogen is used in the place of air as a way to clean surfaces and to remove any dust and debris that is too small to remove manually in other types of cleanroom procedures. This is particularly true when the cleanroom has areas where damp or wet cleaning processes cannot be used.

As nitrogen is both dryer than air, as well as inert and free from the moisture found in most pressurized air systems, it is the natural option for cleanrooms. However, nitrogen itself is damaging to many materials, so the choice of the material used to fabricate the nitrogen spray gun is an important factor in the life cycle and the maintenance required to keep the gun in good working order.

Top Quality Construction

The best nitrogen spray gun is made from PTFE or Polytetrafluoroethylene. This is a material that is also known as Teflon, and it is non-reactive, hydrophobic, and resistant to damage even in high temperatures and in extreme types of environments.

Choosing a spray gun manufactured specifically for use in cleanroom environments is essential to get the maximum duty cycle for the gun. It will also be essential to consider the spray pattern for the gun, the length of the hose assembly and the type of trigger configuration on the gun.

What to Consider

It is crucial to choose a nitrogen spray gun from a manufacturer with a solid reputation in providing cleanroom equipment. In addition, look for systems that are sold as a complete unit, including the gun, hose, and fittings.

These spray guns for cleanrooms may also be custom made for specific requirements in a given facility. This provides the option for the specific features of the gun to be developed to the needs of the operator.
