Lightweight and compact: Low weight under 10 kg, in practical Systainer³ M437 format. Air exchange rate: Extremely powerful air purifier with up to 680 m³/h air circulation. For rooms up to 57 m² at 3 times the air exchange rate per hour. Flexibility for any room size: Depending on requirements, up to six air purifiers can be connected in series. This allows the air exchange rate to be increased and the air quality to be improved. Socket: For connecting additional SYS-AIR air purifiers or power tools. Adjustable: Volume flow can be selected in two stages depending on the amount of dust. Clever: The air flow is dispersed upwards in three directions (left, right, back). This means less swirling up of dust and fewer disturbing air currents. Pre-filter: Filters the majority of the dust and thus protects the main filter. Low-dust, quick to replace and cost-saving. Clean: Specially developed main filter in TripleV shape with particularly large filter surface for less rapid clogging and longer service life. In dust class M. Healthier working: > 99.9 % filtration in dust class M. Signal light: Warns of clogged filters and indicates upcoming filter change. Interface: For connecting a ⊘200 mm supply air hose (accessory) for hard-to-reach areas or dust protection walls. Compatible: Can be coupled with Systainers and vacuum cleaners via T-LOC. Can be integrated into the bott vehicle equipment. Mobile: Easy to carry thanks to Systainer handle. Easy to transport when coupled with SYS-RB roller board or suction cup. Safely tidied away: Power cable fixed in the lid compartment and safely stowed away. The air cleaner filters harmful airborne dust from the air that is not captured despite professional extraction. This prevents them from settling in the environment. Thanks to its compact systainer format and light weight, it is particularly suitable for mobile applications. Thanks to its powerful, two-stage suction.
