   Brevundimonas diminuta in liquid per mod. ASTM F838-83
   and FDA guidelines.

Typical Air Flow Rates *

* Typical initial clean medium P per 254 mm (10 in.) element, air at
20°C (68°F). For multi-element cartridges, divide pressure drop by
number of 254 mm (10 in.) elements. Non-linear cartridge turbulence
factors are incorporated into housing pressure drop values. For
complete assembly pressure drop, add filter cartridge medium value to
housing value at specified flow rate. For gases other than air or nitrogen,
contact your local Pall distributor.

Note: Curve labels denote inlet pressures.

⁴ Contact Pall for multi-element values.
⁵ In air/N2 service or other compatible gases.
⁶ For continuous air flow above 60°C, Emflon PFW filters are
recommended. Emflon PFW can be operated at higher temperatures
for shorter time periods.
⁷ Lab tests to establish multi-cycle resistance. Filters should be
qualified in actual use. Contact Pall for recommended procedures.
⁸ 1 bar = 100 kPa
