ASAB S Series - Replacement S1 Motor Brushes

Keep your ASAB S1 airless sprayer operating at its best with ASAB-S1-22 S1 Motor Brushes. This genuine replacement carbon brush set is a direct-fit service part designed to maintain consistent electrical contact within the motor—supporting smooth start-up, steady running, and dependable power under load.

Motor brushes are a normal wear item, and replacing them at the right time helps prevent intermittent operation, loss of torque, and unnecessary wear to the commutator (which is a polite way of saying it can save you a much bigger repair bill).

Safety Check

• Isolate power first: unplug the sprayer before removing covers or accessing the motor.

• Allow cooling time: motors and housings can be hot after operation.

• Keep ignition sources controlled: brush arcing is normal, but solvents and vapours are not welcome nearby.

• Replace as a pair: mixing old and new brushes can cause uneven wear and poor contact.

• Test safely: run the unit briefly after installation and check for abnormal sparking, noise, or overheating.
