This vacuum is made up of four basic parts: chassis, filter chamber, waste bin, motor housing. The side-channel suction unit, made of aluminium casting is fitted at the base of the chassis, giving more stability to the machine.
The impeller is directly driven, thus avoiding any transmission and maintenance. The special diffuser decreases the speed of the exhaust air to less than 1m/s, in compliance with European regulations EN 60335-2-69. Moreover, the diffuser provides an optimum noise level of 69 dB (A). The vacuum gauge monitors filtration efficiency. The vac is fitted with a external manual filter shaker, located on the side of the machine, easy to use and ergonomic. The greater filter surface is obtained by means of a polyester star filter, 1,95 m² as filtering surface, "L" class as standard.
The Upstream HEPA filter (High Efficiency Particulate Air) is fitted for the presence of toxic/hazardous powders, - Tested by the MPPS method (Most Penetrating Particle Size), according to EN 1822 regulations.
