Caliber 14 x 109mm Piexon (CH)

In regards to the irritant OC agent used, we rely on a trusted formula and years of experience in testing. Capsaicin has proven to be the most reliable irritant agent when used against assailants under the influence of drugs or alcohol as well as against animals. To be able to make a reliable statement on the required minimum safety distance we have conducted extensive wound-ballistic tests performed by a trusted and wellknown ballistic expert. If you have questions concerning the safety of our products we are more than happy to provide you additional research information (law enforcement agencies only).

The JPX emits only a minimum of airborne irritant agent droplets causing the undesired cross-contamination. This makes Piexon products also suitable for indoor use. The technology of "shooting" vs spraying of the liquid OC irritant not only improves accuracy but also significantly reduces the risk of generating aerosols small enough to enter into the respiratory system, which can be harmful for asthmatics.


With more than 13 years of proven experience, Piexon Inc. has a solid background in providing high-end solutions to existing problems.

The issue of long range OC delivery-precision led to the development of the all new 14x109mm Piexon CH canister.

This kind of explosive-driven (7) "syringe" holds a piston (5) in between two burst discs (6 & 2) at the rear and front end. The space (4) between the piston and the upper burst disc is filled with Piexol, a liquid OC-formula.

The chamber extends towards the end (3), allowing the overpressure to pass by the piston O-rings, completely cleaning the canister of any OC left.

The jet nozzle (1) gives the jet its final shape, allowing it to travel for a distance of over 7 meters accurately.
