Ultimate- Direct Wire 12V, White

The part that you are referring to is a ferrite bead. The ferrite bead is required to meet Electromagnetic immunity and emission compliance requirements by the Canadian Standards Association (CSA) and must not be removed. Without this ferrite bead, other electronic devices near the fan may experience electromagnetic interference when operating. This will vary with the specific equipment and proximity to the fan. You can cut the heat shrink tubing off to eliminate some of the bulk surrounding the ferrite. Arrange the wires so that two are on the side and one is on the opposite side. This will allow it to lay flatter.

The body of each fan is made from plastic. Depending on the fan, the plastic used may be FR ABS or ASA. The blades are made of polyethylene.

No. Our fans are not 'ignition proof' certified or tested. In an engine room, there is always the risk of having fuel and hydrocarbon fumes. For this reason, we do not recommend our fans be used in this environment. Our fans use a brushed motor, with an expected brush life of 5000 to 7500 hours. Operating the fans 24-hours will wear the brushes in a shorter time frame than the normally expected duty cycle.

Yes! The 747/757 Ultimate Fans, 817 Kona or 7482 Maestro Fan would be suitable.

Our 747-model fan is manufactured with a cigarette lighter adapter (plug). It also comes with a suction cup mount, in addition to the permanent mount, so it can be installed in various ways and applications.

Our 757-model fan is a direct wire unit and features a permanent mount.

Mounting clamps can be purchased as well. 

We do have several replacement blades available for various units. You can purchase blades for the Ultimate 747 & 757 models on our website. 

To install, pull the faulty blade off the motor shaft and push the new blade hub onto the motor shaft. Please leave a small space between the blade hub and the motor housing so the blade can spin freely. 

The smooth wire is positive, and the ribbed wire is negative.
