Southern Air Specialists, LLC has designed, manufactured and patented a new Fan Bushing Replacement Tool. This tool allows the user to replace the outer glacier bushings on a Variax Booster Fan Hub without performing a complete hub rebuild. The only item that is removed are the blades. Typically, the outer hub glacier bushings are only changed during a full rebuild cycle since they are installed from the inside out "until now!" The Fan Bushing Replacement Tool allows for an easier installation technique than that which is utilized during a full hub rebuild. This tool has been field proven and was developed with long term reliability and cost savings for the Variax end user in mind. Changing these bushings will extend the length of time between full hub rebuilds by keeping hydraulic pressures low. This tool can be beneficial when budgeted rebuild costs need to be deferred to a later fiscal year due to unforseen circumstances. Contact us for further details.
