Bauer Mariner 200/250/300 differences

[aquaregia]

I was looking at the spec differences between the various Bauer Mariners, and the compressor stats (stroke/bore/pressure) seem the identical for all models, with the difference in fill rate being governed by the cycle rate. I imagine there’s some other differences here and you can’t just change out the pulleys to turn a 200 into a 250, does anyone know what these are? Power of the motor? Heat sinking on the stages?

Mariner 200 and 250 have similar base . In standard, small filtration ( P21 )
Mariner 300 have a bigger compressor blok and medium filtration capacity (P31)

Options are similar between all models ( Automatic condensat drain , Automatic stop , intermediate pressure gauge, etc...).

Very good compressor.

Basically motor and and pulley on these I think

You can change the motor pulley to turn a 200 into a 250 but the additional load increases current draw, hence the step up to a larger motor too.

200 and 250 are rock solid units. Probably the best semi-portable units currently being produced. The 320 is popular too, but we do see stages 1/2 getting pretty hot (especially down here in our climate).
