Ecotech Marine MP40w ES operating noise

I would like to retract my statement below - My new one is very quiet, only audible within the room... the older one has a problem of some sort and will be undergoing return/exchange.

I can definitely hear them in the next room though, they are on 100%... it was a bit annoying at first, but I have good ears and low 'annoying noise threshold' lol. It doesn't annoy my folks who hate annoying noises (like the smallest water drip or pump humming), though. Its not obnoxious like loud droning, but its defintely an audible 'whir' as it winds up and down.

Cheers,

Chris

Mp40s are very quiet.

If its loud it's one of these 2 things:

Dry and wet side not lined up perfectly.

And/or

Dry side magnet is rubbing on the rubber spacer. Also the rubber spacer has 3 nipples that need to go into the holes but sometimes they miss the holes and bend and rub against the dry side magnet.

Personally mine are 10's... they have been checked(lined up... no spacers...) ... it is a hardware problem. The good one is very silent.

you're not using the spacer on the dry side? so your magnet is directly exposed to the glass?

The 10's don't have the pin style spacer, they just clamp on or if the glass is very thin below 3/16" i believe then there is a spacer to put in. The 40's have the pin spacer and the 60's have different spacer that slip on.

ohhh ok gotcha. well i found out why my mp40s were making noise. the pins on the spacers bent and were rubbing against the magnet. now they're perfectly silent

Are they quiet at 100% though? Mine are acceptable at lower power, but irritating at full.

They are aligned correctly, using the correct spacer setting, etc.

When you say your pins were bent, is this inside of the unit?

I've bought new bearings to try. I just need to get my hands on a bearing puller.
