The type VAX (vane axial) fan is defned by its name; an axial fan with stationary straightening guide vanes on the discharge side of the propeller. Design allows for a compact inline installation with high static pressure capabilities (relative to other axial fans) of up to 10 in wg. VAX fans sturdy and rugged industrial construction make them well suited for heavy continuous duty industrial applications which include: VENTILATION SUPPLY & RETURN AIR, HEAT, FUME & SMOKE EXHAUST, HEATING, VENTILATING, COOLING AND PROCESS DRYING.
VAX fans incorporate one piece heavy gauge rolled steel inner and outer casings. Outer casings form a round smooth surface for efficient air passage and incorporate drilled flanges. Heavy gauge inner body drivetrain casing is supported by formed steel guide vanes. Motor supports are comprised of rigid formed steel plate with four corner adjustable motor table to insure proper belt tensioning and alignment, which results in maximum belt and bearing life.
Aerodynamic die formed blades coupled with stationary guide vanes eliminate turbulence and recover rotational energy for improved efficiency, enhanced pressure capability and reduced noise.
Aluminum props are good to 250ºF with mild and stainless steel impellers available for temperatures as high as 850ºF. The VAX prop's steep characteristic curve extends the normal selection range to larger volumes without significant loss in pressure capability.
