How Tuff Kote Handles Underbody Rustproofing with Cosmostar Pressure Tank & AM0705 Air Motor
Rust on a vehicle starts where you cannot see it. Underneath, in the cavities and exposed metal surfaces of the underbody, corrosion builds up quietly until it becomes a structural problem. For automotive service providers offering professional rustproofing, the equipment used to apply the protective coating determines how well the job holds up over time.
This is a look at how Tuff Kote approached their underbody rustproofing application using the Cosmostar Pressure Tank with AM0705 Air Motor.
The Challenge: Rustproofing Material Needs to Stay Consistent From Tank to Gun
Rustproofing compounds used in professional automotive applications tend to settle when left static. Heavier particles separate from the carrier fluid over time, and if the material reaching the spray gun is not homogeneous, the coating applied to the underbody will not be either. Inconsistent material means inconsistent protection.
For a service operation like Tuff Kote, where vehicles move through the service bay continuously, there is no time to manually stir the material between jobs. The system needs to keep the material ready to spray at any point during the shift.
The Setup: Cosmostar Pressure Tank with AM0705 Air Motor
The Cosmostar Pressure Tank equipped with the Cosmostar AM0705 Air Motor addressed this directly. The AM0705 air motor keeps the rustproofing material continuously agitated inside the tank throughout the shift, maintaining consistent material composition from the first vehicle to the last.
The pressurized tank delivers material to the spray gun at stable, controlled pressure, giving the operator consistent output regardless of how long the material has been sitting in the tank.
With a maximum torque of 1.3 N/m and rotation speed of up to 2,500 RPM, the AM0705 is well-suited for the viscosity range of rustproofing compounds, keeping the material in motion without over-agitating or introducing air into the fluid.
What the Application Looks Like at Tuff Kote
With the vehicle raised on a car lift, the operator applies rustproofing coating to the full undercarriage in systematic passes. Material flows from the pressure tank to the spray gun at consistent pressure, giving the operator steady output throughout the application.
Between vehicles, the system stays ready. The AM0705 continues agitating the material in the tank, so when the next vehicle comes in, the coating composition at the gun is the same as it was at the start of the shift.
Equipment Summary
Cosmostar Pressure Tank with Cosmostar AM0705 Air Motor: Stores and continuously agitates rustproofing material during production. Maximum torque 1.3 N/m, maximum rotation speed 2,500 RPM. Mountable in various positions with smooth, low-vibration operation.
Running a Rustproofing or Underbody Coating Operation?
If your service involves rustproofing compounds or other protective coatings for vehicle underbodies, a pressure tank system with continuous agitation can help keep your material consistent throughout the shift.
