ARM-EVAC 250 Microprocessor Controlled Fume Extraction

Terms and Definitions

High-Capacity Fume Extractor

*All accessories sold seperately*

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 keypad on the front panel and an audible alarm alerts the operator when a filter change is required. A three-position motor speed button is also on the front panel. A wide variety of collection accessory options and filters are available. An optional silencer/mobile cart is available.

Primary Features:

  • Easy to read LED Filter Condition Monitor
  • Self-calibrating
  • Intelligent air flow compensation
  • Two 3 Inch Inlets
  • Low Noise Level (58 dBA)
  • Can be fitted with a Mobile Cart/Silencer
