Harmsco
Up-Flow Cartridge Filtration

A Design So Superior, It's Patented!

Harmsco's up-flow design outperforms conventional filters! To understand how up-flow systems work, follow the diagram shown above. Fluid enters the filter under pressure and flows through the filter media, holes in the center tubes and perforations in the rods that hold the cartridges in place. As the fluid continues its path through the filter, it flows upward past the top seal where it spills over into the standpipe as it hits the filter's domed lid. Notice that the top of the standpipe is at the high point of the filter. Also, note that the filter cartridges are sealed at the bottom and held in place with threaded pipe caps on the Harmsco model shown in this diagram. This unique design offers the following significant advantages:

No Air Entrapment During Operation

Air entrapment during operation is eliminated because the outlet (top of the standpipe) is located at the high point of the filter.

Because air travels upward with the fluid and exits the filter through the standpipe, vents to discharge accumulated air are not required. (If vents are required for specific applications, lids with vent fitting are available.)

Air accumulation is a common problem with conventional filter designs because their outlets are located below the inlets. Reduced efficiency results since the filter media cannot be utilized where air has accumulated.

Superior Filtration

Since 100% of the media is used 100% of the time, superior filtration is achieved!

Two Filter Types Available

Cartridge Cluster Filter Line

Cartridge replacement is made easy in this line of Harmsco filters since the entire set of cartridges are removed at once for quick cartridge change-out or cleaning.

Twelve Available Models

Harmsco Industrial Filters are available in twelve models for flow rates up to 800 gpm.

Harmsco Reusable Filter Cartridges

Harmsco filter cartridges may be cleaned and reused in most applications. Entire cluster can be cleaned without disassembly.

No Fluid By-Pass During Servicing

Fluids cannot by-pass Harmsco Filters during servicing because the filter's outlet (top of standpipe) is located above the filter's inlet. A significant advantage in critical filtration applications!

Electropolished

All Harmsco Filters are electropolished for increased resistance to corrosion.

Fail-Safe Lids

Lids come standard with wing nuts so they may be easily opened without tools. Multiple studs provide fail-safe closure. No single bolt clamp closure used! (HIF-150-FL and HIF-200-FL filters come standard with hex nuts).

Pressure Rated To 150 PSI

Filters may be safely used in pressures up to 150 psi.

Compact Design

Our compact, space saving design requires less floor space than other filters. We have more cartridges with more filter media than anyone!

Large Capacity Filters Feature Cartridge Lifters For Easy Cartridge Removal

Large capacity Harmsco filters use cartridge filters to remove a stack of cartridges at one time for added convenience. Cartridge lifters can accommodate up to four cartridges, depending on the filter being used.
