Membranes for Diesel Fuel Testing

Pallflex® Air Monitoring Filters




Pallflex Emfab™
Borosilicate microfibers reinforced with woven glass cloth and bonded with PTFE. Flushed with DI water to remove water-soluble residue. Low moisture and low air resistance. Withstands folding for weighing and transport. Preferred filter for ambient air sampling and stack emission testing.

Filter Media: Borosilicate glass microfibers reinforced with woven glass cloth and bonded with PTFE 
Typical Filter Thickness: 178 µm (7 mils)
Typical Filter Weight: 5.0 mg/cm2
Typical Aerosol Retention (Following ASTM D 2986-95A, 0.3 µm DOP at 32 L/min/100 cm2 filter media: 99.95% 
Typical Air Flow Rate: 68 L/min/cm2 at 0.7 bar (70 kPa, 10 psi) 
Typical Water Flow Rate: 32 mL/min/cm2 at 0.35 bar (35 kPa, 5 psi)
Maximum Operating Temperature: Air 260 ºC (500 ºF)

Pallflex Fiberfilm™
Unique combination of heat-resistant borosilicate glass fibers and moisture-resistant fluorocarbon. Moisture variations in air or gases will not cause chemical reactions on the filter. Low moisture pickup and low nominal air resistance. Ideal for diesel exhaust sampling.

Filter Media: Heat resistant borosilicate glass fiber coated with fluorocarbon (TFE)
Typical Filter Thickness: 203 µm (8 mils)
Typical Filter Weight: 3.4 mg/cm2
Typical Aerosol Retention (Following ASTM D 2986-95A, 0.3 µm DOP at 32 L/min/100 cm2 filter media: 96.40%
Typical Air Flow Rate: 180 L/min/cm2 at 0.7 bar (70 kPa, 10 psi) 
Typical Water Flow Rate: 220 mL/min/cm2 at 0.35 bar (35 kPa, 5 psi)
Maximum Operating Temperature: Air 315.5 ºC (600 ºF)
