  • GC11 Condenser Tube Cleaning Gun

The GC11 cleaning gun has the ability to easily and quickly reach all tubes in a condenser, heat exchanger, lube oil cooler, or elevated exchanger. One light squeeze of the trigger allows water to lubricate the tube and brush, and a further squeeze of the trigger propels the brush through the tube, cleaning the condenser or heat exchanger tube in seconds.

    GC11 Tube Cleaning SYSTEMS

    Cleaning systems include GC11 tube cleaning gun(s) and the appropriate accessories to suit your application.

    System 1000 is just right for small heat exchangers

    System 2000 is the right choice for larger heat exchangers, air conditioning condensers, and all HVAC units. This system allows crews to shoot 2 guns simultaneously for faster tube cleaning where no aditional pump is required.

    System 3000 is for use on larger condensers or when time is a major factor. The use of 3 guns simultaenously allows for the most time effecient tube cleaning of large condensers. The job gets done fast with no additional pump needed.
