Prevention of dust and dirt coming in under Waco Compressor fridge

Thanks Peter
Would I have to fit an extra 12 volt fan , one to draw in air and one to push the air out internally if I cover the outside 2 fridge vents?

That's a tough question without having any idea what it looks like Martin. Suffice to say the heat must be removed one way or another.

Cheers,

. . . and cool air has to get in.

Is this fridge located outside the vehicle on an open tray ?

When you say in the topic title "dust and dirt coming in under Waco Compressor fridge" what exactly does this mean, from under the tray or floor ?
Normally there is an inlet grated section (or two) and an outlet for air pumped through.

If there's dust getting inside a vehicle causing an issue, then far better to work on keeping that out and the fridge will be fine with an occasional blow through with moderate compressed air.
