This material is also easy to work with, so you can rest assured that the filter housing you choose will last for a long time.

Aluminized steel

Aluminized steel on filter housings offers several advantages. The material has a heat shield that keeps it from rusting. This makes aluminum a cost-effective material for high-temperature applications. Additionally, aluminum can withstand corrosive agents and is suitable for HVAC equipment and appliances of multiple sizes. The material also performs well against salts. If corrosion is your main concern, aluminized steel on filter housings could be the answer.

Epoxy coated

The Epoxy coated filter housing is made of stainless steel. This type of coating is heat-curable and resistant to extreme temperatures. Neo-Pure uses this one-part epoxy coating on its stainless steel housings. The layer melts, forming a uniform coating coverage. It prevents corrosion loss due to seawater and helps protect against service disruption due to harsh chemicals. You can find this coating on several types of filter housings.
