I would like to know if pump ROB-10398 is reversible. I mean : if I invert the electrical polarity on it, will it reverse the air flow in the tubes?
What is the weight of the unit?
Supplied datasheet does not mention those informations.
Sadly no, you can’t reverse the air flow through the pump because of how it’s mechanically designed.
You can reverse electrical polarity though without causing any issues. (It works just fine in either direction.)
