Husqvarna A 45 Air Scrubber - 970651902
The A 45 is part of our latest generation of air cleaners, developed with a whole new level of intelligence and mobility to meet customer demands. Recommended for spaces up to 45 m² in a single-use set up. A color-coded visual alarm clearly indicates the filter status. The innovative units are compact and stackable – an advantage when it comes to maintenance, transportation and handling. The A 45 can be used as both an air cleaner and a negative air machine. Two- or three-stage filtering captures various particles commonly produced on a construction site, including silica dust and wood dust, as well as dust from metal, gypsum and other materials. The active carbon filter is available as an option.
