AIR EXTRACTION MONITOR EX max 25m³/hr

Item number: 205003W

  • Explosion protected pressure switches for monitoring technical ventilation
  • For notifying a fault in the air extraction system (not in the event of a power cut!)
  • In a store with a min. 2 times per hour air exchange, the effectiveness of the ventilation must be monitored, e.g. using flow monitoring (TRGS 510 Appendix 5 Section 2 (6))
  • Differential pressure switch for volume flow control via measurement of differential pressure
  • For gas, mist, vapour and dusts in zones 1, 2, 21, 22 (non-aggressive media)
  • Sensor as piezo pressure transmitter
  • Switching delay to avoid error messages
  • Default setting 120 sec
  • Ex proof in accordance with ATEX II2(1)G Ex emb[ia] IIC T6 / II2(1)D Ex tD [iaD] A21 IP66 T6
  • Audible signal in switch cabinet when the required air extraction volume is not met (not in the event of a power cut)
  • Notice: When sited indoors, the customer must ensure the air extraction is channelled to a safe location outside. After installation of the extraction ducting the pressure conditions will change and the extraction volume flow will need to be set again by the customer. Our Service team would be happy to prepare a quotation for this readjustment operation.
  • Air extraction monitoring for hazardous materials stores up to 25 m²
