DW400 vs Walbro "525"

Q: When does 400=525? A: When you are comparing the flow of a DW400 vs. a W525. To clear up any confusion on how the DW400 stacks up against the W525, we flow tested both in our technical depart. Numbers don’t lie. Thanks to Bosch’s high torque 29mm motor, the DW400 flows more at higher pressure and draws fewer amps in the process.
