Ventry Safety Propellers

  • 0.00

Ventry® Safety Propellers are dual-blade aircraft style propellers which combine the fundamentals of aerodynamics with state-of-the-art proprietary technology.

We make these props in-house at VSI of a unique composition of Kevlar® (used in bullet-proof vests), fiberglass, and wood. These materials contribute to our propellers having low vibration tendencies, being very durable, and being fail-safe. Every Ventry Safety Propeller is a slightly different shape for efficiency but all of them have forward-sweeping tips which deliver air in a very tight cone shape to a target quite far away (in contrast to the large, erratic, inconsistent circles pushed by other common PPV fan propellers).

For use primarily on Ventry PPV Fans, our propellers are engineered specifically for each motor to maximize that engine’s horsepower and achieve from it the highest air volume possible. Ventry Propellers may work well for your application even if it is not on a Ventry Fan as long as it can safely handle the thrust and meet other requirements.

Technical requirements for using Ventry Propellers:

  • When in use, any fan on which a Ventry Propeller is used must be raised, allowing for at least 6 inches of clearance between the ground and the propeller tips.
  • Ventry Propellers have a four-bolt pattern with 2-9/16" bolt centers (distance measured between opposite bolts across the center of the prop).
  • The motor to which you connect the propeller must have a straight shaft and a 3/16" key.

The following Ventry Propellers are available:

  • 20-inch propeller for 1.5 hp motor
  • 20-inch for 3.5 hp motor
  • 20-inch propeller for 4.6 or 4.8 hp motor
