How Does a Pneumatic Nail Gun Work?

New users are always alert to know the best technique for a Pneumatic Nail Gun because the wood shouldn’t be damaged by inappropriate use. Here, I will describe how does a pneumatic nail gun work most perfectly and quickly. It is going to be a definite guide for users.

First, it is very mandatory to know what a pneumatic nail gun is. Second, I need a deeper explanation about the pneumatic nail gun.

What is a Pneumatic Nail Gun? 

What is a Pneumatic Nail Gun? 

A compressed air-powered nail gun that works pneumatically is known as a pneumatic nail gun. The loading capacity of the pneumatic nail gun for the nail is more than three and a half in length. As it is beneficial in framing, it is also known as a pneumatic framing nail gun.

Pneumatic nail guns are a little bit expensive because they work with an air and need a compressor. 

Parts of Pneumatic Nail Gun

Some significant parts of the pneumatic nail gun:-

Air Compressor 

The 1st major part is the air compressor. It generally works with gasoline or electricity and supplies the compressed air in the air reservoir using an air hose pipe.

Air Reservoir

The Air reservoirs generally push the air resulting in triggering the air. Air that is reached in the air reservoir helps deliver this air into the holding space.


A piston that comes with a standard shaft, this combination is known as a driver found in conventional style pneumatic guns. The function of this part is to contact the gun’s head. When you press the trigger of the pneumatic nailer, the valve will unblock, and it pressurizes the air into the cylinder. Basically, it makes the pressure on the piston greater than below.


The Final major part is the piston. Inside the cylindrical body, there is a piston that works with a valve. The function of the piston is to help occupy the air in the right place. 

How does a pneumatic nail gun work diagram – common mechanisms

Beginners feel too much trouble when using a pneumatic nail gun because they directly use it without understanding its proper use. So, it is essential to know the appropriate working mechanism.

First, you need a compressor and an air hose to use this type of nail gun. These work like an intermediate channel between the nail guns. The compressor releases compressed air that will mainly work to drive down the hammer onto the nails at the barrel. Must maintain a safety mechanism before releasing compressed air. 

For power, there is a trigger valve mechanism. When compressed air comes, the valve hinders the air from accessing the chamber. The nail gun will fire after pressing the plunger on the material that you want to fasten. The valve will not permit compressed air to flow into the chamber unless you pull the trigger. So, you have to pull the trigger to let out the compressed air.

Plungers and hummers attach with a blade inside the chamber. So, you have to push down the plunger on the material as fast as before the compressed air arrives at the blade. When you do this, the compressed air transports the plugger and follows up on the hammer. The compressed air makes sufficient power to drive the hammer down and fire at your components.

How Does a Pneumatic Nail Gun Work- step by step

A pneumatic nail gun will drive a nail appropriately when you direct the nailer in an accurate direction and pull the trigger.

Before starting your work, check the hidden pipes, and electric wires beneath the surface of the wall. These safety cautions will remain safe from shocks and other malfunction of your pneumatic nail gun. You can check it by electricians and remove it. Let’s go through all the steps of how does a pneumatic nail gun works.

Step 1: 

The air compressor creates air pressure and compresses it to the highest level by attaching it to the base. Inside the unit of the pneumatic nail gun, there are regulators. It acquires the proper amount of pressure. Before pressing the tip of the gun, place it on the vertical surface.

Step 2: 

The safety mechanism maintains its powering system before releasing pressure. This mechanism blocks the compressed air within the unit to prevent unnecessary fire without pressing the plunger. When you get perfectly set up, close the safety and hold down the trigger.

Step 3:

Air pressure will release in the chamber after pulling the trigger. In that place, a blade is attached to the hammer. When you press the plunger onto the material, compressed air tries to lift the plunger. After that, it pushes the hammer. It is important to keep the pressure adjustable with the surface.

Step 4.

The barrel fires the nails by creating extra force onto the hammer. One nail shot can release only one nail at a time. A blade determines this process.

There is no chance of losing pressure for frequent usage because when the pressure is reduced, the compressor automatically rebuilds the optimal pressure level. The whole mechanism provides consistent work with continuous use.


You can increase the pressure a little bit as much as you need. Such as if the nail works slow or needs to be made faster and go through properly. Turn the knob at the top to increase the pressure of the gun. 

You can also reduce the pressure if you think it’s the extra force that loses your surface and wall as well. Before going through practical work, test the pneumatic nail on the surface of the scrap pieces. Thus, you can enjoy error-free nailing with this pneumatic nail gun.

How to use a pneumatic nail gun – Useful Tips

Some safety tips you should maintain before using a Pneumatic nail gun. 

  • Check your all fittings and airlines are working or not before connecting to the air supply. Make sure these are free from leaks and tangles.
  • Make sure triggers are moving properly, and screws which are used for retaining are secure.
  • Familiarize yourself with the manufacturer’s operating instructions like handling and storage of the nail gun for use.
  • Don’t forget to wear safety equipment like safety footwear, safety glasses with a side shield, and hearing protection.
  • At the time of firing, try to keep your hands free from the discharge area.
  • Keep your finger disengaged from the trigger when you are not firing at all. Try to pull the trigger only when the nose piece is pointed to a secure work page.
  • Never excess while using the nail gun.
  • Don’t point the nail gun at someone else. Consider the nail gun as a firearm, and suppose you loaded it.
  • If you find any interruptions or maintenance problems, try to disconnect the equipment as soon as possible from its air supply. But make sure that before working on the tool, the air is totally finished.
  • When your work is complete, remove all fasteners and nails and replace the pneumatic nail gun with the proper storage space. 

Final Verdict

Professionals’ favorite nail gun is the pneumatic nail gun because it can do heavy tasks in a short period of time. Several workers are injured every year because of nail gun incidence. 

Though nail guns are one of the popular equipment for fastening materials easily and quickly, you must use them properly, or you will be at serious risk. That’s why you have to know how a pneumatic nail gun works and how to use it. Hopefully, this article will help you.
