VAX - VANEAXIAL FANS

VAX - VANEAXIAL FANS

The type VAX (vaneaxial) fan is defined 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.

About VAX - VANEAXIAL FANS

Wheel Type Specifications

Maximum flow (ACFM): 500 – 175,000 SWSI
Maximum pressure: 10 in. wg
Maximum Temperature: 850ºF
Static Efficiency: 65%
Material Handling: no

Aluminum alloy or steel propeller with heavy gauge aerodynamic curved blades. Produces large volumes of air at moderate pressures. Robust propeller in heavy gauge steel housing with stationary guide vanes allow for maximum efficiency and higher pressure capability than standard axial fans. Standard catalog sizes from 120 (12” Dia.) to 840 (84” Dia.) with custom sizes available.

Item Details

The type VAX (vaneaxial) fan is defi ned 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 incorporate one piece heavy gauge rolled steel inner and outer casings. Outer casings form a round smooth surface for effi cient air passage and incorporate drilled fl anges. 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.

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.

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

Configuration Examples

Sealed belt tunnel and bearing tube protect the drivetrain assembly from contaminants in the airstream. Belt tunnel is accessible beneath the belt guard and bearing tube is accessible through inner body end tube caps. Guide vanes are welded to both the inner and outer body tubes providing rigidity and support that minimizes vibration and casing noise. For high temperature designs the bearing tube can be modified; VAX fan shown above has insulated bearing tube and belt tunnel along with an auxiliary cooling blower.

Versatile mounting in horizontal, vertical (shown above), and angular positions with mounting brackets, feet and collars optionally available for each orientation to allow for ease of installation. Vertical configurations incorporate axial locking mechanisms for bearings and propeller.

All units come standard with extended lube lines for easy access to grease zerks.
