UPDATED: This listing is for the 2nd Generation of our REX Blaster Nozzle, which now includes an upgraded top cover for better straw management and a safety cap. If you already own a 1st Generation REX Blaster Nozzle Head, you can upgrade yours with a seprate parts kit or 3D print your own upgrade parts with designs available on Deviant Ollam's GitHub. This unit is fully backwards-compatible with all previous and current air canisters and valve fittings sold on Red Team Tools.
For some time now, penetration testers have been making entry into buildings via bypassing of Electronic Physical Access Control System (E-PACS) doors by triggering Request-to-Exit (REX) sensors. These sensors, located on the inside of such doors, are typically configured to detect motion by means of monitoring the infrared spectrum. Thus, large objects that are either warmer or colder than the ambient temperature typically will trigger the REX sensor and often release the locked door.
Often, penetration testers will use canned air products such as spray duster (containing Difluoroethane) or r134a refrigerant (containing Tetrafluoroethane) to create a cloud of cold gas which can trigger these sensors. Typically, however, canned air products of this nature are bulky and not easily concealed within a pocket or the palm of one's hand.
But our Air Canister Nozzle Head is designed to accept small screw-top air tanks and canisters of the sub-100 gram variety that are popular in many civilian applications. From CO2 gas canisters used in brewing and airsoft sport to marine air horn refills, this nozzel head can adapt those cans and offer the user push-button release of the gas within. Hold the canister upside-down to release pure liquid propellant out of our nozzle adapter such that it will boil off in the atmosphere, creating the desired cold air effect.
NOTE: Not all gasses will produce the same type of cold air release. Carbon Dioxide, while cheap and abundant, will create a smaller cold gas cloud which will dissepate quickly. Green gas, Difluoroethane, and Tetrafluoroethane all tend to release thicker clouds of condensate, albeit at somewhat greater cost and the gasses themselves are not as stable as CO2.
Our Gen2 REX Blaster Nozzle Head includes a top cover that will hold the included straws stable for directing cold gas through thin cracks in doors and windows, as well as a safety cap to prevent accidental deployment before you've approached a target. A set of spray straws are also included. NOTE: Straws should be considered consumable items and replaced from time to time, as they may easily become damaged during insertion into tight spaces.
