What Is in a Paslode Fuel Cell?

A recent wrinkle on nail-gun technology has been the invention of guns that get their impulse from the detonation of a small quantity of flammable gas rather than compressed air. The gas comes from a cylindrical fuel cell that is loaded into the back of the tool. Paslode is one of the major manufacturers of these.


Cordless nailers are used for many construction tasks.

The Paslode fuel cell is relatively simple in its construction, being designed solely for the purpose of storing a pressurized quantity of propellant gas. The outside of the cell is a thin-walled metal cylinder with crimped edges on the ends. The bottom end is a concave hemispherical shape (to help resist the outward force of the pressurized gas) and the top end has a small plastic housing which contains a right-angle interface tube through which the gun can draw metered amounts of gas.


The fuel cell contains the combustible gas used to actuate an internal hammer that drives the nail. The mixture used in Paslode cells is typically a mix of Butene and Propane.


The fuel cell is inserted into the back of the gun, bottom end first. The interface tube of the cell is pressed into a receptacle in the top of the chamber. A hinged plastic door is closed over the chamber to protect the cell from contamination or damage.
