Hello again.

I just received my combustion blower. Speedy service!

Now I have a quick question. I noticed that my old combustion blower, has what looks like silicone, sealing the blower to the furnace and fresh air tube. Is this a special silicone?

Also, are these blowers oiless? Mine is making a noise. Some of it has to do with the fresh air tube rattling, some sounds like the bearing going bad. I bought a new one from you just in case this one went out. We don't have too many HVAC guys around that like to mess with mobile homes.

High heat resistance silicone . Some of the motors are sealed and some are manually lubricated.

IF it can be oiled, it will have oil ports/spouts on it.

Some people are Humbly Grateful, while some are Grumbly Hateful.................... Which one are you ?
