Vacuum blasting machines general overview and technique

The LTC series vacuum blasting machines are fully integrated and can provide continuous recycling operations. The continuous recycling feature of LTC equipment permits the use of long life abrasive media; 12 to more than 200 cycles, depending on the media choice and surface treated.

 

The models LTC 1020 through LTC 1050 use a suction technique to transport the abrasive to the blast head. Both the LTC 1060 and the LTC 1070 utilize a single chamber or unique double camber pressure vessel system.

Due to a renewed design of the pressure vessel of the LTC 1070, it is now possible to work with a blasting pressure as low as 1 bar and as high as 8 bars with the same machine! This means that the LTC 1070 vacuum blasting technique can be used on delicate blasting jobs where blasting on low pressures is a must.

 

All LTC machines come standard with a special lightweight blast head, blast and vacuum hose assembly, as well as a set of brushes to treat flat surfaces, inner and outer corners. Other brushes and attachments for a wide range of curved and other special shaped surfaces are available or can be engineered and home made. The very special fibres used in LTC brushes ensure best performance and economy.

 

The LTC machines are all available with an electrical driven vacuum generator to minimize the compressed air requirements.

The models LTC 1030, LTC 1050, LTC 1060 and LTC 1070 are available in the fully pneumatic version, eliminating the need for any direct power supply. The choice is yours.
