The Skyblade Mini Prop is a small-diameter HVLS fan built for spaces that can't fit a full-size 20+ foot fan but still need real air movement — think fitness studios, shop floors, and restaurants where noise matters.
The Mini Prop uses a totally enclosed, gearless ECM direct drive motor — no gearbox means fewer wear parts and a quieter fan over its service life. That design, combined with an onboard VFD, is what allows this fan to run in sound-sensitive spaces like offices and fitness centers. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
System Components
- Totally enclosed direct drive ECM motor, 1.35 HP (1.0 kW) nominal, IP65 rated (water- and dust-tight)
- Onboard Variable Frequency Drive (VFD), factory-assembled and programmed for smooth low-torque start/stop
- Three extruded anodized aluminum airfoils, E420 profile with STOL technology
- Three nylon 66 wingtip fences (standard black; additional colors available) to redirect airflow downward and reduce wind noise
- 1/4-inch powder-coated steel and anodized aluminum chassis with stainless steel safety brackets
- 15 ft. factory-wired pigtail for installation
- Remote control (included per product title)
Installation Requirements & Accessories
- Voltage and phase: [NEEDS VERIFICATION] — not specified in manufacturer data provided
- BMS (Building Management System) integration is supported via analog signal at the onboard VFD
- Structural mounting: stainless steel safety brackets are included; overhead structural support requirements (I-beam, truss, etc.) are [NEEDS VERIFICATION] — confirm via the Resources tab before installation
- Mounting hardware compatibility with wood trusses is NOT confirmed in manufacturer data — verify before ordering
- A separate VFD controller is NOT required; the VFD is factory-integrated onboard the motor
- Fire alarm relay integration is NOT confirmed as a supported feature in manufacturer data provided
Pro-Installer Tip
The onboard VFD is factory-programmed, but the field wiring to the BMS analog signal input is where installers most often introduce noise into the control loop. Route the analog signal and any control wiring in shielded cable, separated from motor power conductors, to prevent electromagnetic interference from corrupting start/stop or speed commands. Before energizing, Megger test the motor windings to confirm insulation integrity was not compromised in shipping or handling. Because this fan mounts overhead and connects to building power, installation and disconnect wiring must comply with NEC requirements for a local, lockable disconnect within sight of the motor — do not energize the unit until that disconnect is in place.
Key Benefits
- Direct drive, gearless motor design reduces moving parts and mechanical noise compared to gear-driven HVLS fans
- HVLS technology moves large volumes of air at low speed, reducing energy use versus multiple small circulation fans
- STOL-technology airfoils and wingtip fences direct airflow downward for more even coverage in the occupied zone
- IP65-rated motor tolerates dust and washdown-adjacent environments such as automotive shops
- Compact 7 ft. or 8 ft. diameter footprint fits smaller rooms where full-size HVLS fans will not
- Corrosion-resistant powder-coated steel and anodized aluminum chassis suited to cold, damp conditions

FAQ
Does this fan run on single-phase or three-phase power?
[NEEDS VERIFICATION] The manufacturer data provided does not specify voltage or phase for the Skyblade Mini Prop. Confirm electrical requirements with Polar Cool or refer to the Resources tab before ordering.
What is the minimum ceiling clearance required for this HVLS fan?
[NEEDS VERIFICATION] Minimum mounting height and obstruction clearances were not included in the manufacturer data provided. Check the Resources tab for installation drawings before finalizing your ceiling layout.
Is a variable frequency drive (VFD) included?
Yes. The Mini Prop ships with an onboard VFD that is factory-assembled and pre-programmed for smooth, low-torque start and stop. A separate VFD controller is not required.
Can this fan be tied into a building fire alarm system?
[NEEDS VERIFICATION] The manufacturer data provided does not mention fire alarm relay integration for this model. Confirm with Polar Cool if this is a project requirement.
