      Model: CFZZ6

      Description: CFZZ6 Mining Ventilation Resistance Tester

      MA: MFA140219

      KA: KFA140056

      ExibI: 320140827

      Patent No. ZL 2012 2 0322596.3

       

      Introduction:

      1. Applicable for test of wind speed, absolute pressure, differential pressure, CH4 concentration, temperature and humidity.

      2. Comprehensively analysis the loss of line ventilation resistance, local resistance of fan station, resistance distribution of ventilation system and wind pressure, distribution of air volume.

      3. For coal mining, non-coal mining, tunnel and other roadways, provide them a scientific basis for ventilation system ' s design, study, safety evaluation, construction and mining.
