ST 4 MAXI ATEX 21
Motorised ATEX ZONE 21 industrial vacuum cleaner with three-phase side channel turbine, of our production and made in die cast aluminium. Extremely sturdy, silent, powerful and reliable and suitable for continuous use 24 hours a day. Made entirely of steel, the vacuum cleaners are extremely sturdy and can therefore be used in any working environment for vacuum cleaning dust
The MAXI version has a larger filtering surface compared with the standard ST models
The aluminised Class M cartridge filter is conductive, ensuring the discharge of static electricity and protected by a special PATENTED cyclone made of stainless steel, which, combined with the tangential type inlet, favours the cyclonic effect, avoiding direct contact of the vacuumed material with filter, thus reducing clogging.
PATENTED SEMI-AUTOMATIC FILTER SHAKER
The filter shaker is formed by a mechanical-pneumatic piston, which, by moving up and down, violently hits the bottom of the filter thus creating the vibrations required for perfect cleaning and also reducing operation time. This function is performed automatically by moving a lever on the machine.
