Abstract
A retrofit kit for exhausting gases is provided for removing combustion products from a gun turret. In some embodiments, the combustion products are toxic gases that include ammonia, hydrogen cyanide, and carbon monoxide. The retrofit kit includes a fan and an EMI filter. The fan and the EMI filter are attached to the gun turret with one or more seals that provide both environmental and EMI/RFI protection. In operation, the fan is activated in response to the firing of the gun, and is powered using the power supply provided to the gun turret. In some embodiments, the fan operates for a predetermined time interval after the last operation of the gun.
