    Optibelt for Exhaust fans

    I got a flier from Optibelt Corporation, looks like they cover exhaust fan belts. They claim longer life from their belts in exhaust fan applications. Anyboby had experience with these belts? If their claiams are true, what a time saver for me.

    Talking Molded belts

    If your belt size is 47" or above these are the best belts out there. More horsepower and smooth face Not the sawtoothed pulley eaters like X series belts. for large horsepower multi-belt applications they're a once a year change perfect for service contracts. I call them Feburary belts because you change them after evrything slows up a bit.

    The 47" and above belts I have no problems with. Its the stinking A18, A19, A20, 3L220, etc. Work is too cheap to put idlers on them, availible from the O.M. Which would give me a longer, more wear surface, belt. Less radius around the pulley and self tensioning.

    I knew a guy that knew a guy...really, that worked for Opti-Belt. He gave us a free set of 5V1400 belts. We used them on an Air Handler. Those muthas lasted 3 friggen years of 24/7 operation. Not a single crack. They did thin out a little. We finally changed them out. I hate em. Can't make any money selling these puppies if they don't wear out.

    I've found that those red belts that are segmented and can be atached to provide a fit for any belt work great in those applications,they last a long time and you just buy several feet of the stuff than match it up on the job.

    Thumbs up 47" is the magic number

    47" is the cut off for molded belts if it is less than 47" it is a spliced belt made from a straight corded belt with a splice that wants to find a way to straighten out again (like everyone elses belts) so the point is not much differance on the small stuff.
    ps. beware of homemade belts good for a 2 AM call but not much else!

    I've been using them almost as long as the original post. Absolutely love them in all sizes. They last so much longer than any other brand of belt, there is no comparison. They rarely crack, which BTW will destroy the bearings if not caught soon enough. One of the other guys here hates them. He "pops" the belts over the pulleys, and has ruined motors and fan bearings.
