Precision Motor Control. PMC matches the motor speed to the pressure and tip size selected. 
No pulsation at any pressure with any size tip.
No Rust Fluid manifold.
Only High-grade Stainless Steel and Aircraft-grade aluminum are used.
No cylinder to wear out.
Long-life fluid manifold.
Built for professional use.
All metal construction.
More powerful PMDC motor results in the lowest amperage use in its class.
High-efficiency motor/controller results in 10% more output than competitive models.
