Pneumatic Cable Cutter

Pneumatic Cable Cutter

Sever Bars or Cables in Milliseconds

Designed to sever the cable of a device in tow in the event of an emergency, Marotta’s Pneumatic Guillotine is the first pneumatic cutter to replace pyrotechnics in a military application.  The Pneumatic Guillotine is also ideal for in-flight refueling hose and drogue applications. 

By using high-pressure compressed air, Marotta’s Pneumatic Guillotine eliminates costly pyrotechnics and their associated blast residue, improving safety, maintenance and logistics issues.  Designed with high reliability and long service life in mind, the anvil and blade are repairable, and the entire system is depot replaceable.
