Cleanroom Nitrogen Spray Gun Applications

Check out our selection of nitrogen spray guns for cleanrooms, labs, and manufacturing facilities.

As an inert gas Nitrogen, is cleaner and drier than air, which makes it one of the best surface cleaning products in a cleanroom environment. Nitrogen spray guns are used to accurately dispense nitrogen. But how does nitrogen work to remove debris from your projects and workspace?

How Nitrogen Spray Guns Fit into a Cleanroom

PTFE poly constructed nitrogen spray guns are mounted to wet benches and work process stations, so they’re ready to use in hostile environments, such as semiconductor fabrication plants and other sterile manufacturing facilities.

These industry-standard nitrogen spray guns offer optimal protection against corrosion and resist acid fume deterioration in environments with nitrogen dispensing and drying.

Pressurized nitrogen is used to blow away microscopic dry dust and fibers which have fallen onto a surface and therefore aren’t removable by using tweezers or gloved hands. These particles also aren’t removable by washing, wiping or other cleaning processes because these are typically spaces you cannot get wet. To use a nitrogen spray cleaning system, hold the nitrogen spray gun perpendicular to the item to be cleaned, then engage the gun’s depress button.

When a mist of nitrogen gas is sprayed, it releases tiny particles from the surface you’re working with within seconds. The power of the nitrogen gas stream and distance from the object being cleaned will determine how fast the particles are removed.

If the offending material is sticky, nitrogen won’t be effective. Instead, consider using an acetone washing bottle.

Note: Nitrogen spray guns should never be directed at the user’s, or a co-worker’s, skin. The pressure can inflate and lift the skin, causing tears and severe skin damage, especially if any cuts or abrasions are already present.

How To Choose A Nitrogen Spray Gun (N2 Spray Gun)

Most cleanroom nitrogen spray guns are sold with the gun and a coiled hose or with the gun sold separately so that both parts can be replaced independently of one another. When purchasing these separate items, be sure the male connector from the nitrogen spray gun and the hose are the same size, often 1/4″ to 1/2″, for cleanroom applications.

PTFE poly constructed nitrogen spray guns have a unique design that eliminates expensive nitrogen leaks. The spray guns also utilize in-line capsule filtration pads which further purifies the stream of nitrogen.

Here's a quick checklist for choosing a nitrogen spray gun assembly.

Spray Direction Of The Nitrogen Spray Gun: You can choose between a model that sprays the N2 gas straight out of the top of the nitrogen spray gun, or one that sprays it from the front of the nitrogen spray gun (at a 90-degree angle).

Hose On The Nitrogen Spray Gun: For the hose on the nitrogen spray gun, you can choose a blue, coiled polyurethane (PU) hose which is resistant to oils, solvents, and weak acids and bases. Or you can choose a hose that is PTFE (FEP). This Teflon hose is made by Chemours (a spinoff of DuPont), and it provides a higher level of anti-corrosion protection from harsh chemicals.

Trigger Location On The Nitrogen Spray Gun: You can choose a nitrogen spray gun that has a rear trigger that you depress with the palm of your hand, or a front trigger that you activate with your finger.

Nozzle On The Nitrogen Spray Gun: Please note that all of our nitrogen spray guns have the same type of nozzle.

Does your microelectronics, pharmaceutical or sterile packaging facility need to upgrade or install cleanroom nitrogen spray guns? Cleanroom World offers a variety of nitrogen spray gun assemblies, filter discs, and coiled hose assemblies.
