Specification MV  -  Mixed flow for high vloume flow and high pressure performance.  Made of high-grade polymer.

Specification MVZ - Two MV fans are connected in series using a connecting sleeve and assembled on a common base plate.  Delivered as ready to assemble kits.  Series operation doubles the pressure output at the same volume.

Specification MVP - The two parallel MV fans are mounted on common mounting rails and have a connector plate fitted to both the intake and exhaust.  Delivered as ready to assembly kits.  Parallel operation (both fans running) doubles the air volume at the same pressure.
