The Festool 500558 main filter fits CT SYS and CTC SYS dust extractors. It is the standard main filter, designed to trap particles down to 1 micron, while maintaining good airflow. This lets you reach full capacity without clogging or caking. Proper filtration eliminates the majority of dust right at the source of emission, before it is ever released into the air, resulting in a cleaner, safer shop.
Note: Not suitable for mobile dust extractors with Autoclean function.
