Ventry Safety Propellers

• Ventry Props are made in-house at VSI of a unique composition of Kevlar^® (used in bullet-proof vests), fiberglass, and wood.
• Ventry Propellers have low vibration tendencies, are very durable, and fail-safe (watch a video where we prove this).
• While each Ventry Safety Propeller has a slightly different shape for efficiency, 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).

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
• 24-inch for 3.5 hp motor
• 24-inch for 4.6 or 4.8 hp motor
• 24-inch for 5.5 hp motor

Even though our props are created specifically for Ventry Fans, they can also be used on Non-Ventry fans, as long as the following technical requirements are met.

• 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 of the guard. This allows a Ventry Propeller to spin freely and not touch the guard.
