³Removal efficiencies based upon a modified ASTM F795 Dynamic Single Pass Efficiency test.

⁴Pressure drop in psid per gpm for the cartridge length shown. Multiply this value by the total system flow to determine the aqueous pressure drop. Note, for fluids other than water, multiply this value by the fluids viscosity at the operating temperature in centipoise. This value is the pressure drop across the Marksman PFT High Flow filter(s) only; it must be added to the pressure drop due to the High Flow filter housing. For kPa/lpm, multiply mbard/lpm by 0.1000.

Filter Installation and Filter Seal Mechanism

To install a filter element, remove the element hold down plate by lifting it off the locating pins. Lubricate the O-ring on the open-end of the filter with a compatible fluid, and slide the closed end of the filter into the perforated cage, which is welded to the tubesheet. Seat the elements in place by pressing down on the open-end of the filter until the element is snug in the tubesheet. This provides a seal between the filter and housing via the filter O-ring. The open-end cap must be below the tubesheet surface. After installing all the filter cartridges, reinstall and secure the element hold down plate by guiding it over the locating pins on the tubesheet. The purpose of the hold down plate is to prevent the elements from becoming dislodged in the event of reverse flow.

A filter element tool is provided with each housing to aid with the installation and removal of the filter cartridges. This tool eliminates the need for an operator to reach within the filter vessel to either remove or install the filters.

Housing Design

Three configurations are available: horizontal, vertical and centerpipe design.

The in-line horizontal configuration eliminates the need for a platform, or ladder, to remove the filters from the housing.

Vertical vessels may be more appropriate when floor space is limited. However, a platform may be needed to easily remove the elements.

In both the standard horizontal and vertical configurations, the inlet pipe is located between the filter element tubesheet and housing lid. The larger the vessel diameter, the longer the distance to reach in and remove the elements from the vessel. In a centerpipe vessel the housing lid is closer to the filter tubesheet. When the lid is opened the filters are easily accessible for installation and removal.

• Designed to the ASME, section VIII, division 1 code
• Maximum differential pressure across tubesheet: 75 psid (5.2 bar) maximum
• Standard housing gasket: spiral wound 304 stainless steel mineral fiber
• Carbon steel exterior surfaces: sandblasted and coated with an inorganic zinc
• Vent and drains: 1 inch FNPT
• Corrosion allowance: 1⁄8 inch

♦	Optional Outlet Size5 Horizontal Housings
XU	Upper Outlet Location
XL	Lower Outlet Location

⁵ If the housing is to be used as a prefiller to a horizontal liquid/liquid coalescer, then the vessel should be ordered using the XU or XL option for the outlet location. The orientation of the outlet should be the same as that of the sump on the coalescer. In this way no buildup of coalesced liquid will occur in the prefiller.
