Can I buy a Ventry Propeller?
Ventry Propellers for Retrofit
You can purchase a Ventry® Propeller but if it will be used on something other than a Ventry Fan, please read this page!
Ventry Propellers are available in 20-inch or 24-inch lengths and for a variety of motors.
- 20-inch propellers for 1.5 hp motor
- 20-inch propeller for 3.5 hp motor
- 20-inch propeller for 4.6 or 4.8 hp motor
- 24-inch propeller for 3.5 hp motor
- 24-inch propeller for 4.6 or 4.8 hp motor
- 24-inch propeller for 5.5 hp motor
In addition to the prop, you may also need the aluminum hub, due to the unique bolt pattern Ventry Props have (see below for more details). Most people do need the hub and James, our CEO and Mechanical Engineer, not only reviews each propeller order to make sure the application is safe and appropriate, but he's also happy to answer any questions you may have about your current hub working with one of our props.
Prepare for Thrust!
Ventry Propellers produce a great deal of thrust. If your fan is not designed to handle the thrust, it will tip over backwards with our blade on it (if enough air reaches the propeller, depending on its guard/cage). The outward curving, asymmetrical legs on Ventry Fans are designed to handle the thrust produced by the propellers. Other fans, for example those which operate close to the ground and have a small footprint, are not able to handle this thrust.
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.
- There must be at least 3 inches between the front of the shaft and the front guard. This allows a Ventry Propeller to spin freely and not touch the guard.
*If your current fan meets all technical requirements except this one, then you may need to purchase the before-mentioned aluminum hub in-addition-to a propeller.
