Materials of Construction

Filter Media:

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

No silicone is intentionally used in materials of construction or in manufacturing.

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

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 loading capacity 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.
