Description:
Pall 2237 series filter elements are extremely permeable and are constructed
of high dirt capacity stainless steel (type 304 or 316L) woven wire mesh. 2237 series media out perform other meshes because they are sintered woven wire meshes with higher void space.
Pall sinters the wires at their points of contact, producing an extremely strong porous material whose wires will not shift under stress and whose pore size integrity is continually maintained. This patented Pall process permits use of finer diameter wires in manufacturing the filter medium.
The net result is a filter with more pores per unit area, providing more dirt-holding capacity than that of an unsintered mesh made from coarser wires. Designs are available which are suitable for temperatures up to 600F/315 C.

Filter Element Pressure Drop
Multiply actual flow rate times factor in table below to
determine pressure drop with fluid at 32 cSt (150 SUS),
0.9 S.G. Correct for other fluids by multiplying new viscosity
in cSt/32 (SUS/150) x new S.G./0.9.
Note: factors are per 1000 L/min and per 1 US gpm.
Operating Characteristics:
Standard cartridges are capable of withstanding a collapse differential of 125
psid in the forward flow (outside-in) direction and up to 600 F and 10 psid in the
reverse flow direction
Sizes:
The standard series filters are cylindrical forms of pleated medium, 2 1⁄2inches
in diameter in 10 inch multiple lengths, up to 30 inches.
