    BAC damper

    Got a small cooling tower with a damper on top. It's got to be 10 to 15 years old. The damper is extremely had to move. The mod motor can't open it. I'm going back tomorrow to spray it down with some WD40 or something. Anyone else got an idea?

    wd40 will collect dust and bind up dampers try using graphite spray, started using it on outside air dampers and works great drys and does not collect dust

    WD to loosen and than graphite spray to lube...but i will tell you if this isn't done more often it will get worse. But i wouldn't spend a lot of money on this or even replace them. the dampers are very expensive... and not really necessary.

    The graphite lube worked great.
