3M filtration products for automotive assembly.

Ask an Expert

From pretreatment to electrodeposition, we have the filtration products you need to streamline your operation and reduce rework. Filtration is used throughout the automotive washing and painting process.


Filtration in Automotive Assembly

Having the right filtration for automotive assembly operations is more important than ever. Competition, efficiency, productivity and water conservation are just some of the reasons it’s important to pay attention to this vital aspect of your operation.

From surface treatment to washing and rinsing and e-coating to spray booths, 3M filtration has the solutions you need to help maximize your water and application processes.

  • Infographic of the 8-step process map for industrial water filtration in automotive assembly.

Source Water

OEM paint systems consume the greatest amount of water in the manufacturing environment. Water sources have different filtration needs.

Multi-Cleaner Stage

Typically has the most contaminants. Examples include dirt, oils/greases, waxes, paint chips and Kevlar. Polypropylene filtration ideal for alkaline chemistries at moderately elevated temps.

Coating

Zinc phosphate generates sludge that requires systems to handle heavier loading. Thin film treatments avoid sludge buildup and use traditional filtration.

Rinses

Water rinses capture residual solids from previous stages. Problem areas can be organic growth that require routine cleaning and/or disinfecting.

eCoat Bath

Tighter filtration removes contaminants without removing paint solids. eCoat filtration designed to remove contaminants without stripping paint solids.

UF/Permeate Rinse

Permeate rinses return paint solids to eCoat bath. Ultrafiltration used to separate generated permeate. Traditional filtration removes larger contaminants.

Paint Booth

Ecoat cured autos enter paint kitchen for primer, base coat and topcoat application. Classifying cartridge filters retain paint additives while removing contaminants.

Car Wash

Vehicles undergo a final car wash prior to delivery.

Applications for Automotive Assembly

We’re here to help. For more than 100 years, 3M has partnered with our customers to develop innovative filtration and purification products to help in their processes.

Incoming Water

The water you use in your automotive assembly must be filtered to reduce particles that can affect the quality of finished vehicles. The type and level of filtration needed depends on the source of your water.



3M’s filtration products provide the particle reduction needed to deliver the high-quality water needed for automotive assembly applications.
