Circuit Specialists Portable Desoldering Tool System

Note: We also stock a similar unit, the BK3090, bundled with a soldering iron.

The CSI8900 is a compact desoldering gun which houses a powerful suction system driven by a reciprocating piston. This enables the CSI8900 to develop much greater suction that other de-soldering systems that implement pump only suction technology. Also included is a PTC ceramic heater and variable temperature control circuit all in a slick ergonomic design. The key feature of this unit is the incredible suction developed by the reciprocating piston. The piston is driven by two internal pumps (one for push and one for pull) far surpassing the suction obtained from the typical pump only desoldering systems.

  • Portable and powerful desoldering tool for servicing and repair.
