The POWER InDust AX 60 TP Z22 vacuum cleaner features an ATEX 22 - II 3 D Ex tD IIIB T135°C X IP55 Dc certified side channel blower suction unit which is directly connected to the crankshaft. The absence of transmission devices makes the suction unit not only silent and powerful, but it also allows continuous use (h 24) without any need for regular maintenance. The magneto-thermal motor protector allows the turbine to operate properly in any condition. Engine cooling is continually guaranteed by a vacuum limiter valve equipped with an anti-static safety filter. The vacuum gauge, thanks to a constant monitoring of the air depression level, is able to detect the level of clogging of filters or of other parts of the suction system. All the electrical components of the machine are explosion proof (EX). The high-efficiency (M antistatic class) and large surface (2 m²) filtration filter can be easily cleaned thanks to the practical, manual filter shaker which is able to guarantee a very long filter life, avoiding clogs, saturation and the reduction of the filtering capacity. The quick-release recovery container and the sturdy tray equipped with non-marking wheels make the vacuum cleaner extremely easy to use. POWER InDust AX 60 TP Z22 is available in three phases version, with M class certified.
