The Festool SYS-AIR Standard (Non-HEPA) Air Filter with LS-SYS-AIR D200x6m Air Supply Hose is a portable air filtration system built to clean shop and jobsite air after fine dust escapes your main extractor. This is a portable air filter designed for capturing fine airborne dust in workshops and construction-site work areas. Model Number: 577790-577964. If you sand, drill, or saw indoors and want less floating dust, less cleanup, and a cleaner finish at the end of the day, this is the setup Festool built for that exact problem.

What makes this unit useful is that it handles the dust you cannot always see right away. Even with solid dust extraction at the tool, fine airborne particles still hang in the room and eventually settle on floors, benches, tools, and finished work. Festool rates the SYS-AIR at up to 680 m³/h, which gives it the airflow needed to circulate room air aggressively instead of just moving it around. Festool also states it can clean rooms up to 57 m² at three air renewals per hour, so this is not a gimmick add-on. It is meant to make a real difference in enclosed work areas.

The filtration side matters just as much as airflow. This unit uses a two-stage filter system and is rated for dust class M applications, with a stated filtration level of more than 99.9%. Festool specifically calls out wood dust and mineral dust, which tells you exactly where it fits in real work. For remodelers, finish carpenters, cabinet installers, flooring crews, and anyone doing dusty interior work, that means cleaner air during the job and less dust spread into occupied spaces.

Festool also did the practical jobsite details right. The main filter uses a TripleV shape with a large filter surface, which helps slow clogging and extend filter life. There is also a contamination indicator that shows when filter performance is still good and when the filter is too dirty to maintain the required air renewal rate. That kind of feedback matters because it takes the guesswork out of maintenance. Instead of wondering if the unit is still doing its job, you get a clear signal.

On portability, the SYS-AIR stays true to the Festool system approach. It comes in a Systainer³ M437 format, weighs under 10 kg, and includes a carrying handle. That makes it easier to move from room to room, into finished spaces, or back to the van without treating it like a bulky shop-only machine. Festool also notes the power cable stores in the Systainer lid, which is a small feature but one that keeps transport and storage cleaner and less annoying.

The included LS-SYS-AIR D200x6m air supply hose broadens where this setup works best. Festool calls out awkward spots and dust protection walls as key use cases, which is exactly where a hose like this earns its keep. Instead of placing the unit only where it fits, you can direct airflow where the clean air is actually needed. That is useful in temporary containment zones, tight rooms, and renovation spaces where layout is never ideal.

System compatibility is another strong point. Festool states the SYS-AIR can connect to all Festool Systainers and extractors thanks to T-LOC, and it can also be transported on the SYS-RB roll board or an extractor. There is also an electrical outlet module with continuous current so you can connect an extractor, a power tool, or additional air purifiers. If you already work inside the Festool system, this unit fits the workflow instead of forcing a separate one.

Who should buy it? If your work creates fine dust indoors and cleanliness affects your speed, your finish quality, or how professional the job looks when you leave, this makes sense. It is especially well suited for contractors working in occupied homes, finished remodel spaces, shops, and enclosed jobsite areas where dust control is not optional. If you need true HEPA filtration, this exact version is the standard non-HEPA model, so that is the point to pay attention to before you buy.
