Technical Data

Materials of Construction

Filter Media:

Meltblown polypropylene microfiber filter media provides high particle removal efficiency for high quality filtration with broad chemical compatibility.

o silicone is intentionally used in materials of

construction or in manufacturing.

Features, Advantages and Benefits

The 3M™ Hi gh Flow Filter Cartridge 740B30, which incorporates the patented radial pleat, puts an extraordinary amount of surface area into a single cartridge. This results in the following:

• High loading capacity for long life and lower cost filtration.

• Fewer cartridges for fewer change-outs and lower labor cost.

• Fewer seals, reduced risk of bypass resulting in high quality filtration .

• Extremely low disposal costs, less than a tenth of some cartridges.

Double O-ring seals in a variety of material options means:

• Extremely low risk of bypass for high quality fluids.

• No loose parts to assemble for easy installation, thus less labor cost.

• Also, no springs and caps to lose reduces the risk of bypass.

• Broad chemical compatibility for many applications.

• Convenient handle for easy manual or mechanical removal.

The raw materials composing these filters are FDA compliant according to CFR Title 21.

Performance Data

Loading Capacity

Product Number 742B 743B 744B 745B 746B 747B 748B 749B

Pounds at 30 gpm 8.9 13.4 13.3 13.3 13.7 16.1 17.3 17.5 Kilograms at 7 cu m/hr 4.0 6.1 6.0 6.0 6.2 7.3 7.8 7.9

Loading: The data above shows typical loading capacities of the different micron rated filters. Loading capacity is determined by challenging a filter with a dispersion of silica test dust in water at the recommended flow rate. Pressure drop is monitored and testing is terminated at 50 psid (3.4 bar). (742B is terminated at 35 psid– 2.4 bar.) The loadi ng cap aci t y reported is the dry weight gain of the cartridge.

Efficiency: The 3M™ High Flow Filter Cartridges are rated using a silica test challenge in water at 30 gpm (6.8 cu m/hr). The results reported are typical initial efficiencies taken within ten minutes of the start of the test.
