Main applications:
For carcinogenic or pathogenic dust with a limit value of ≤ 0.1 mg/m⊃;3;
Removal of mineral dusts during smaller grinding, milling, sawing or drilling work, e.g. in the case of plasterboard
Ideal for mobile work in maintenance and assembly work and final cleaning
Suitable only for dry vacuuming
CTH MIDI AC safely removes hazardous dust, such as mold and asbestos, wood protection agent impregnations, mineral fiber dust, lead, cadmium, nickel and zinc chromate. With a filter dust separation rate of 99.995%, the vacuum cleaner is a specialist in removing carcinogenic and pathogenic dust.
The automatic main filter cleaning system AUTOCLEAN (AC) keeps the filter free and ensures consistently high suction power, longer working intervals, a longer filter life and lower maintenance costs.
Thanks to its small weight, compact dimensions and a whole host of innovative details, such as Bluetooth® technology and a smooth suction hose, it is ideal for maintenance and installation work.
Usage permit: dust class H.
Safety: for carcinogenic and pathogenic dust, such as asbestos.
Securely sealed: with a two-layer safety filter bag.
AUTOCLEAN: more efficient, automatic main filter cleaning system to ensure consistently high suction power. Cleaning intervals (15, 30, 60 or 120 seconds) can be set via the app. Full cleaning in the case of a heavily clogged filter.
Mobile: ideal to take with you thanks to its compact dimensions, light weight and durable chassis.
Intuitive: touch control for the feel of the vacuum cleaner.
Automatic socket: for cable-connected electrical tools. When the electric tool is started, the vacuum cleaner also starts automatically.
Smart: easy replacement of the main filter from the outside.
Smart: thanks to the integrated Bluetooth® technology, the vacuum cleaner starts automatically via the Bluetooth® battery or remote control.
Smooth suction hose: with conical geometry for trouble-free processes and strong suction power without hooking.
Convenient: T-LOC function for easy connection of the Systainer to the mobile vacuum cleaner.
Very powerful: consistently high suction power thanks to the compact high-performance turbine – adjustable in 5 steps.
Antistatic function: prevents static electricity generated during operation.
Order set: hose storage and cable winding holder for better order and safety.
Gross equals net: maximum use of the container volume.
Smooth storage area: ideal for storing tools and work materials.
The vacuum cleaner can be used for dusts of dust class H. It is suitable for removing harmful dusts with limit values of ≤ 0.1 mg/m⊃3;. In addition, a sound signal sounds if the suction flow is too weak.
The technically further developed AUTOCLEAN (AC) function ensures automatic cleaning of the main filter. This keeps the suction performance constantly high.
Thanks to the two-layer safety filter bag, dangerous harmful substances are safely trapped (e.g. asbestos). The filter bag is surrounded by an additional single bag.
Instead of rotary switches, the device has a new touch field, which is easy to handle even with gloves, as well as in case of soiling. Immediately after switching on, the vacuum cleaner is in automatic mode.
Smooth, elastic and extremely durable. The smooth suction hose impresses with optimal handling and longer durability. The hose slides over all edges and, thanks to its conical shape, ensures the greatest suction power. In addition, the vacuum cleaner automatically adapts to the correct diameter of the suction hose.
The flat support surface above the hose holder can be used as a seat or to hold tools and materials during work. Via SYS-DOCK, Systainers can be easily connected to the vacuum cleaner and transported thanks to T-LOC.
Thanks to the large hose holder integrated in the device, storing the smooth suction hose is even easier and transporting the hose is safer and cleaner. Spacious.
Switching on the vacuum cleaner from the remote control or via the Bluetooth® battery. This is convenient and reduces footwork.
The well-thought-out container geometry and space-saving flat filters allow the container volume to be used to the maximum.
With the smart folding mechanism, the cable can be removed in an instant.
The bayonet connection connects the suction hose firmly and quickly to the electric tool. For individual regulation of the air flow through the bypass.
The vacuum cleaner communicates with the Festool application and gives you suggestions on how to work faster. In addition, you can view your vacuum cleaner usage data.
The parking brake ensures a firm stay. The rotating wheels and their material are low-wear. Thanks to the balanced center of gravity, the vacuum cleaner is easy to carry.
Thanks to its compact and ergonomic design and light weight, the vacuum cleaner is particularly easy to transport.
The filter is replaced from the outside without opening the vacuum cleaner.
