    Top Quality Liquid Filtration Solutions

    Our Harmsco Up-flow filter housings use multiple filters to deliver high quality water filtration that is perfect for heavy-duty applications. The patented up-flow design of these cluster cartridges allows them to utilize 100% of the cartridge surface area, providing efficient filtration and improved filter life. Built with rugged stainless steel construction and electro-polished to resist corrosion, these durable filter vessels and components will deliver a stable supply of filtered water at a fast flow rate with high volume for all your most demanding commercial and industrial applications.

    Superior Upflow Design

    Harmsco's Up-flow filter housings outperform conventional filter designs because the outlet is located above the inlet to eliminate air entrapment during operation. With up-flow filters, liquid enters the vessel through the inlet, located at the bottom of the filter. As the liquid travels upward, it flows through the filter media, past the top seal, separating the dirty and clean water chambers, and down the standpipe as it exits the filter. Because the top of the standpipe is located above the top seal, air is self-purged from the filter to eliminate vents and improve filtration efficiency.

    Why Should You Filter Your Water?

    Cool, clear water is the life force in manufacturing operations. It cools, cleans, and can be counted on to run pure and steady - unless it becomes contaminated with dirt and other pollutants, in which case it can gum up a system, increase the friction losses and induce erosion corrosion. Water contamination also wastes energy by increasing the demand for a higher flow rate to offset the lost capacity due to scaling. This can impede operations, lowering the thermal efficiency of the system and even impair the quality of the products being made.

    Water filtration is one of the most effective and least expensive ways to solve equipment fouling and scaling problems caused by dirty water. Heat exchangers, molds, pipes, tubing, sensors, monitors, and other parts become fouled when dirt particles in the water settle out on warm surfaces. Calcium and magnesium are the bonding elements that cement the dirt onto the equipment. Chemical analysis shows that the calcium and magnesium are less than 2%, while the rest is made up of airborne particles, rust, sand, biological organisms, and other contaminants. High concentrations of water pollutants can result in the need for costly repairs or replacement of the facility's mechanicals. Our up-flow commercial housings are designed to deliver unsurpassed filter performance which enables longer filter runs and reduced filtration costs to keep your equipment running efficiently.


    Pressure Drop

    Low Pressure Drop

    Initial pressure drop with Harmsco filters and replacement cartridges is exceptionally low because our pleated cartridge design provides more surface area for reduced resistance to flow. This chart indicates the initial pressure drop for Harmsco cartridge cluster filters with 20 micron cartridges in clean water.



    Standard filters with CPVC holding rods, pipe caps and standpipes with standard Harmsco cartridges are temperature rated to 140°F (60°C). Models with stainless steel internals are temperature rated to 200°F (93°C) with Harmsco High-Temp cartridges. Results may vary; ratings are based on pressures and time under load.


    Cartridge Installation

    Lid Removal   Cluster Filters   High Capacity Filters
    Manually remove wing-nuts or hex nuts for easy filter cartridge access.   Install cartridges on holding rods and secure with straight thread pipe cap.   Install cartridges on cartridges lifters, one stack at a time.
