SFA-2590 Part Change Notice

The enhanced SFA-2590 has evolved in several positive significant ways.  Compared to the original, the enhanced model:

  • Is 50% lighter making it easier to carry and handle.
  • Will accept a Teflon (GF-2590T), Quartz Silica (GF-2590Q) or Borosilicate Micro-Fiber (GF-2590) filter.
  • Has a reduced diameter which means less blockage of the stack by about 2 square inches per traverse point.
  • Uses fewer parts, which means a lower price
  • Requires a MPT-6-320 pitot tube
