Nilfisk SC UNO 4M 140/620 PS Stationary Cold Water Pressure Washer
The Nilfisk SC UNO 4M 140/620 is One Machine with Total Flexibility.
Most pressure washers make you choose between portable and permanent — the Nilfisk SC UNO 4M 140/620 does both. Wall-mount it as a fixed installation in your wash bay, then pull it off and carry it to a different site the same day.
Delivering 2030psi (140 bar) at 620 L/hr through a brass pump head with three ceramic-coated pistons and a slow-speed 1450rpm motor, this is a machine built for heavy-duty daily use across light agriculture, automotive, construction, and building maintenance.
Coming in at just 34kg, it's significantly lighter than comparable machines in its class without sacrificing any of the build quality you'd expect from Nilfisk. Delivered ready to use with all accessories included — unbox it, plug it in, and get to work.
