The Arm/Evac 250 is ideal for heavy/duty operations that need high capacity and continuous particle filter monitoring. Incorporating microprocessor technology, an easy/to/read graphical LED filter condition monitor changes from green to yellow to red as the filter becomes clogged.
Additionally, flow sensors increase power to the motor as filters become blocked to assure peak performance. The filter monitoring system self calibrates using a membrane/switch on the front panel and an audible alarm alerts the operator when a filter change is required. A three/position motor speed switch is also on the front panel. A wide variety of collection accessory options and filters are available. An optional silencer/mobile cart is available.
