Model A2G-mini Differential Pressure Gauge

Brand: WIKA Alexander Wiegand SE & Co. KG
The model A2G-mini differential pressure measuring instrument is used for monitoring differential pressures of the filter units in small and medium-sized central air-handling units. 

Further application cases are in industrial air extraction units and dust extraction plants as well as in the cleanroom industry. Its compact design and flush panel mounting enable an optimal integration in the enclosure structures of ventilation equipment.
Features
  • Optimal readability with minimal space requirements.
  • All-metal design.
  • Simple and quick mounting.
  • Silicone-free.
