The IV 60/30 M B1 is a very robust industrial vacuum cleaner, especially developed to handle dusts of the dust explosion classes ST 1, ST 2 and ST 3 in the zone 22. The construction type and the various accessories available make it highly mobile, being used in different sites of the factory and practical for different cleaning tasks. The model is recommended to be used for continuous duty (3-shift-operation) because of the motor type embedded in it. The side channel turbine creates a high suction power. The "easy-empty" drop bin fitted with wheels facilitates easy transportation of the vacuumed material. The two castors with built-in brakes ensure a good stability even when the machine is placed on slopes. The cyclone pre-separator is a standard feature and it pre-separates large amounts of dust before they can get into the filter area. As a result the life-time of the filter is considerably expanded. A main filter with a very large filter surface and a high dust absorption rate (material dust class M approved) ensures long operating periods with no interruption. A manual, external filter cleaning device, guarantees long operating periods and ensures a long life-time of the filter. The accessory support placed at the front side of the machine allows a comfortable storage of the entire suction accessory set. In the additional accessory basket can be stored the small nozzles and tools. The cable hook is a convenient cable storage during work and transport duties.
