Industrial vacuum RI 331 D4 IE2-IS-H

RI 331 D4 IE2-IS-H: For vacuuming small quantities of solid materials, carcinogenic and combustible dusts in non-explosive areas in continuous operation. Robust machine with dust class H.

The RI 331 D4-IS-H IE2 is a robust, mobile industrial vacuum cleaner which is suitable for smaller quantities of combustible and carcinogenic dust (OEL < 0.1 mg/m³). It features dust class H filter engineering and a powerful, energy-efficient (IE2) side channel blower for high vacuums. The 3-phase AC, low-maintenance motor with a rated input power of 4.0 kW enables the continuous, low-noise three-shift operation of the vacuum cleaner. A durable, washable pocket filter and a manual shaking mechanism for filter cleaning ensure constantly high suction power. The 50 l container can be emptied without removing the drive head via an ergonomic set-down trolley. A PE bag – included in the scope of supply – with an integrated closing mechanism guarantees low-dust emptying and safe disposal. The vacuum cleaner is suitable for installation in non-explosive areas.
