The Model 88 is an accurate and stable EFA instrument for area Effective airflow measurements of vane rings, combustors, segments and diffuser rings. These EFA machines can also be multipurposed for your testing requirements. CCDI is the leader in Effective Flow Area (EFA) measurement.

Model 88 Scientific Effective Flow Area Test Machine

Model 88 EFA Scientific Comparator

Flow Capabilities

  • Area: 0.425 to 30 Square Inches EFA (40 Sq. In. Optional)
  • Pressure: 0" to 20" Water Column gauge
  • Pressure or (Vacuum, optional) Measurement
  • Equipment Turn-down ratio 110:1

Specifications

  • NIST Traceable EFA (traceable orifice plates available)
  • All air density parameters are measured
  • Room and Plenum Temperatures
  • Barometric and Plenum Pressures
  • Dew Point (Humidity)
  • No reference blower needed
  • 30 H.P. AC Blower Motor - Optional Blower Range Configuration (40 H.P. with 40 Sq. In. EFA Option)
