Why Is Up-Flow Such A Big Deal?
This product is designed with a patented Up-Flow Technology which prevents the accumulation of air inside the filter housing, keeping the filter operating at 100% efficiency. In a typical competitive multi-cartridge filter, there is a potential for air entrapment. With outlets located below inlets, air travels upward so vents are needed to expel air that can accumulate within the filter vessel during operation. There is also a potential for by-pass. With outlets located below inlets, by-pass can occur as unfiltered liquid drains downward to the sump while the cartridges are removed. This may result in by-pass when the filter is put back into service.

3M™ Scotchkote 134 Fusion-Bonded Epoxy Coating is a one-part, heat curable, thermosetting epoxy coating designed for corrosion protection of metal. The epoxy is
applied to preheated steel as a dry powder which melts and cures to a uniform coating thickness. This bonding process provides excellent adhesion and coverage on applications such as valves, pumps, pipe drains, hydrants and porous castings. Scotchkote 134 coating is resistant to wastewater, corrosive soils, hydrocarbons, harsh chemicals, and sea water. Powder properties allow easy manual or automatic application by electrostatic or air-spray equipment.
- Suitable for elevated temperature service in presence of H2S, CO2, CH4, crude oil and brine.
- Long-term performance history in water, sewage, and other service environments.
- Scotchkote 134 coating has been tested and certified to ANSI/NSF Standard 61, Drinking Water System Components.
- Scotchkote 134 FBEC meets the requirements of AWWA Standard C213 and C550.
- Operating temperature dry is 235°F/ 113°C
