The Wall Breaker from BCB is a non-explosive, compressed air cannon which fires standard plastic water cooler drums breach walls, gates and doors for rapid quick entry. It can be fired every 10 to 15 seconds. The water jugs can be filled with water, sand, or other materials. Material choices can be made to mitigate collateral damage offering an alternative to explosive entries.
Because the projectile contents are so variable, the exact range (3 to 90 meters/10 to 300 feet), kinetic energy, etc are all dependent upon the state of the projectile contents (i.e. solid, fluid, etc), weight and environment factors. However, BCB was kind enough to provide us with this graph that is based on their trials.
BCB also related to SSD, “The pressure is also a user definable factor and more is not always better, the nature of the projectile and the intended range. It’s process of collating your own data as the targets users attempt to breach are different the world over.”
The Wall Breaker’ uses dive tanks and its high pressure hosing and regulators are safety tested to far beyond the Safe Working Pressure (SWP) of the Wall Breaker. Additionally, a safety blow-off valve is fitted to ensure that the pressure vessel cannot be over pressurized. The Wall Breaker can be set up as a stand alone system or mounted on a vehicle and can also be fired remotely.
