The Festool Bluetooth AIRSTREAM battery packs communicate with the Bluetooth module on the CT mobile dust extractors (requires Bluetooth module upgrade on the extractor). Using one of these batteries enables you to benefit from Festool's entire dust-free system when working with Festool cordless products. With the Bluetooth battery fitted the CLEANTEC extractor starts automatically when switching on the cordless tool.

AIRSTREAM technology with its cooling function greatly reduces charging times and increases charging capacity. When used with a Festool SCA 8 rapid charger, charge times are more than halved when compared to conventional chargers. The batteries feature a charge status indicator, displaying the remaining capacity at a glance. An integrated rubber frame around the battery protects your workpiece and the battery pack, when putting the machine down.

Individual selection of the lithium-ion cells used to make up Festool's cordless batteries ensures every battery gives optimum charge and discharge cycles. AIRSTREAM batteries are ideal for machines with high power consumption.

Bluetooth lithium-ion (Li-ion) battery pack with AIRSTREAM function for all Festool 18 V cordless tools (except CXS, TXS, ETSC 125, RTSC 400, DTSC 400).
