I'm just finishing reinstalling our fan and housing after disassembling it and having the motor bearings replaced. Since these units are aging and beginning to wear, I thought that I'd pass along some of what I learned in the process, and some referrals, since this model is obsolete and parts for the fan (except for bearings for the fan motor) and its housing are no longer available. If the motor on yours is beginning to sound a bit noisier than usual, its time to have the bearings replaced. This can and should be done before the motor burns out (that nasty loud grinding noise usually precedes the final burnout...) 1) If you are willing and able to dismantle the housing and remove the motor (with fan still attached) the bearing replacement can be done by a local machine shop. While its dismantled, you can use the opportunity to clean the ports and the inside of the housing. A word of caution when doing this work: the housing is very brittle and easily cracked. For those mechanically inclined, this is not a particularly difficult job; it just requires considerable care in handling it so as not to break anything in the disassembly, temporary storage, cleaning, and reassembly processes. 2) There are also two alternatives for those less ambitious: Dennis Dietz of Ventilation Advisors, LLC, will provide a quote for either a) a replacement housing/fan system, new with 3 year warranty, or b) for having the existing VMPK fan rebuilt and the housing and fan cleaned by them. In the latter case, he encourages clients to send the unit intact and very carefully packed. Dennis can be reached at www.ventilationadvisors.com or through email (drdietz941 [at] gmail.com) or you can call him at (941) 730-6271. I understand that Dennis was involved in the design and installation of many of these systems in the late 1980's through the 1990's, including at a number of cohousing communities. He is very accessible and knowledgeable. I found his guidance invaluable as I worked on mine. Dennis is still working part-time at American Aldes: Dennis Dietz, Engineering bbgl American ALDES Ventilation Corporation 4521 19th Street Court East, Suite 104 Bradenton, FL 34203 (941) 351-3441 Fax (941) 351-3442 email: dennis.dietz [at] aldes.com http://www.aldes-us.com Also, attached are some information pieces on the Aldes VMP-K system which Dennis emailed to me.
