PS10merce companies and warehouses that need to refurbish returned or used tools for resale. The unit uses high-frequency sound waves to generate cavitation bubbles in a cleaning solution. These bubbles collapse violently against the surface of objects, lifting off hardened paint, lacquer, adhesives, and other stubborn residues without damaging sensitive surfaces.
Unlike manual scrubbing or solvent soaking, ultrasonic cleaning provides a safer, faster, and more eco-friendly approach. Whether you're maintaining HVLP spray guns, powder coating tools, or airbrush kits, the PS20 delivers consistent, deep-clean results in minutes.
Why Spray Guns Become Clogged
After each spraying cycle, paint residue is exposed to the spray guns. Wet paint, primer, coating material, and solvent residue build up inside the internal channels, fluid passage, and nozzle over time.
Paint starts to cure and harden if cleaning is put off, which can result in:
- irregular spray patterns
- Nozzle obstruction decreased the quality of atomisation
- erratic paint flow
In car paint shops, this is one of the most frequent maintenance issues.
3L Ultrasonic Spray Gun Cleaner Applications
- Automotive Painting Shops: Cleans spray guns, nozzles, and paint filters efficiently
- E-commerce Refurbishment Centers: Restores returned spray guns and painting tools for resale
- Woodworking and Furniture Units: Removes varnish and paint residues from precision applicators
- Coating & Finishing Lines: Maintains precision spraying equipment with zero downtime
- Tattoo & Art Studios: Ideal for cleaning airbrushes, nozzles, and paint mixers
- Manufacturing & Assembly: Keeps tools and spray parts in optimal working condition
- DIYers & Home Workshops: Perfect for restoring clogged spray guns and nozzles
What Ultrasonic Cleaning Actually Removes
Ultrasonic cleaning works incredibly well at eliminating:
- Wet paint residue
- Light-cured coatings
- Solvent and oil accumulation
- Dirt within passages and nozzles
Narrow internal structures that are difficult for brushes to reach are cleaned by the cavitation process.
It is particularly appropriate for daily workshop use and routine spray gun maintenance.

How Ultrasonic Cleaning Works
Ultrasonic cleaning utilizes a process known as cavitation. When the machine operates, ultrasonic transducers emit high-frequency vibrations into the cleaning liquid. This causes microscopic bubbles to form and collapse rapidly, producing shock waves that dislodge dirt, paint, and debris from every surface of the object-even in narrow nozzles, screw threads, and internal crevices.
No brushes. No scratching. No missed spots. Just rinse and reassemble after cleaning-your spray guns will work like new again.
