The IFEX impulse gun is the centerpiece of impulse technology. The gun made of stainless steel consists of a power chamber, a high speed valve, a pistol grip with release mechanism and a water/agent chamber. The power source is 25 bar compressed air.

When the valve opens, the compressed air forces the agent out of the barrel at high velocity within milliseconds. The fire extinguishing agent is discharged with high momentum, high penetration effect and high fire cooling power.
