Pre Treatment

The K Factor Filter has been successfully installed in automotive manufacturing and assembly operations where there was a need for highly efficient filtration of washing and pre-treatment of assemblies prior to painting.

Some of the challenges that are faced in this application are:

  • High costs of water and chemical usage
  • Inefficient filtration and clogging
  • High rate of defects from residual dirt and oil

Here are examples of a number of specific applications:

Deluge Process

Deluge is using a series of cannon-like nozzles to aggressively hit the manufactured vehicle with very high flow of water to remove the debris from the manufacturing process

The challenge

After the deluge washes the unwanted dirt from the vehicle this dirt is now in the tanks and must be removed by draining the tank or filtering.

The K factor Filter has been very successful at filtering out all the dirt.

  • Remove weld balls that float
  • Remove weld balls that sink
  • Remove sealer
  • Remove Kevlar
  • Remove sand and grit
  • Remove all the dirt with the k factor filter.
