Multi-Layer Media Design

The media composition of the SureStop 319Plus filter consists of two multi-layered pieces of media, and is designed for high paint holding capacity, as well as high efficiency on paint overspray particulate.

Prefilter Layer – composed of a dual-density, heavy-duty, synthetic paint arresting media. The initial layer is a blend of four fiber sizes, forming an open media for collecting large quantities of overspray material. The second layer is a densified material made of a single fiber size, providing a graded density material for added depth loading and structural support.

Efficiency Layer – composed of a polypropylene fine fiber layer, between two layers of polypropylene scrim material for increased strength and durability.

Self-Sealing Design

The finished filter is formed by sonically bonding the media around an internal wire support frame. The bonding of the media around the frame forms a built-in gasket between the wire support frame and holding frame that secures the filter in place and seals it to prevent bypass. The self-sealing design provides the fastest, easiest installation of any extended surface filter on the market.

Aerospace Applications

Because of the hazardous nature of the chromate paints used in painting aerospace vehicles and components, there are NESHAP efficiency requirements for the filters used in these applications. These requirements are based on the EPA Method 319 Test, which is a particulate efficiency test using both a dry particulate (potassium chloride) and a wet particulate (oleic acid).

When tested per the EPA Method 319 Test protocol, the SureStop 319Plus filter exceeds the NESHAP requirements in existing 2-stage aerospace applications.
