Rooftop Axial Fans - YFRTX
Volume range: 800～130,000 m³/h
Static pressure range: 0～700 Pa
drive type: Direct Driven
Installation: rooftop mounted
- Air performance design
- Optimized design of CFD flow field simulation, repeatedly validated.
- Impeller cutting the air flow asymptotically, air flow direction is stable and high in consistence.
- 3D curved blade design: Guide air to flow smoothly and reduce turbulent current.
- Structure performance design
- Computer aided design of CAE for optimizing structure performance.
- The connection technology of hub and blade is highly reliable.
- Blade end vibration effectively reduced by aided design, prevent blade distortion or breaking after long time running.
- Advanced process
- The 3D curved blades are formed by mould pressing to ensure precision.
- Special tooling is adopted for hub to ensure precision.
- Special tooling is adopted for the installation of blade to ensure performance.
- High balancing level
- Balance quality grade up to G2.5 (Typical products are balanced to G6.3 only).
- Keep running safely and steadily for a long time.
- Extend service life of the fan.
- Diverse selection
- 16 kinds of specifications, the maximum impeller diameter is 1800mm.
- Impeller material: carbon steel, stainless steel, alloy aluminum, FRP coated.
- Performance characteristics: Smooth airflow and saving energy
- Patented propeller-type axial wheel: Excellent aerodynamic characteristics and sound characteristic.
- Fan internal with well organized airflow and the pressure loss is small.
- The clearance between the impeller and tube wall is limited. To be reduced the energy loss caused by the secondary flow and more efficiency.
- High efficient area width without overloading.
- Appearance design：Strong wind resistance, Novel and practical
- Low streamline wind band: reduces wind load.
- Pitched wind band baffle: drains snow rapidly by gravity.
- Suitable for strong winds.
- Modernize buildings with enhanced taste.
