Steel bearings - factory sealed, self lubricating with noncontact seals
Corrugated Vanes - ensures rigidity and avoids shipping damage.
Weatherproof and Dustproof Tubular Casing - minimum bearing maintenance under most severe conditions.
Locked-On Rotor - prevents loss or damage in the highest winds, yet the ventilator is easy to service without special tools.
Bearing Suspension - bearing assembly keeps friction loading low to ensure that momentum keeps the head spinning in sporadic winds.
Box-Girder Construction - used for rigidity & permanent alignment.
Radial Bearing - for minimum friction drag and long operating life.
Support Spider Assembly - designed for greater strength.
Minimum Clearance Between Base and Rotor - for draft reduction and reduces air leakages, improving overall performance.
Corrosion Resistant Finishes - standard ventilators include 2-pack painted finish. Stainless steel & aluminium materials also available.
Applications
Through natural forces, the Rotary allows hot and contaminated air to escape an enclosure, improving the surrounding environment for employers and for better production conditions. The wind driven spinning action, plus the buoyancy of hot air rising (stack effect), plus the natural action of wind pushing through and out of a building all add up to help drive fumes out of a building and encourage fresh air to enter a workspace. No running costs! As with all of Western's natural ventilation products, the Western Rotary requires no electrical running costs or other associated cost such as wiring, which provides for a more budget friendly long term solution. Western Rotary Ventilators - The strong silent type! As there are no electric motors and high-speed fan blades, the ventilators are comparatively silent, which helps to improve working conditions for factories and adjoining offices, resulting in greater employee comfort and efficiency - naturally.
Materials & Options
Ventilators - Painted Steel (standard), Aluminium or Stainless Steel.
Bases- Galvabond , Z/Alume, Aluminium or Stainless Steel.
Dampers (throat mounted) - 3 control options - manual quadrants; pull cord; or the most common electric actuators fitted to the base-damper.
Specification
Supply and install Western Rotary Ventilators. Units shall be mounted on manufacturer's square to round bases. Ventilators shall have bearings encased in a factory sealed replaceable cartridge. Ventilators shall have locked-on rotor and neoprene isolation mountings. Include dampers and manual (or electrical) controls.
