  • M-19 to M-23 have 15° Intervals.
  • M-26 to M-33 have 11.25° Intervals.

Depending on the Arrangement specified, inlet and discharge ducting flange or ducting lip connections are available. See product literature for each model's standard connections.

  • Ducting Flange and Lip Connection.
  • Check Literature for Standard Connections by Model.

Standard paint finish is a baked polyester coating over phosphatize-cleaned steel materials.

  • Highly Durable Polyester Coating.
  • Steel is Cleaned and Prepped Prior to Coating.
  • High Abrasion Resistance for Long Life.
