8.2.2 Filter Compatibility
The following table shows sample filter requirements. If non-corrosive target gases are being
monitored, use filter type A, (P/N 780248), a sample line dust/ particulate filter.
For monitoring corrosive gases, such as chlorine (Cl
chloride (HCl), and hydrogen bromide (HBr), sample lines in a dusty environment or for
outdoors, use filter type B, (P/N 1830-0055), or type C, (P/N 1991-0147) filter assembly for
corrosive gases. The Teflon membrane particulate filter is designed to prevent dust and dirt
greater than one micron from entering the sample line. Unlike standard particulate filters, it
does not exhibit sample loss with corrosive monitoring.
The one micron Teflon membrane contained in the filter housing (P/N 0235-1072, 100 per
pack) should be replaced every 30 days.
Filters have an arrow on the side of the filter pointing in the direction of airflow toward the
Vertex M system. Replacement of filters is site dependent.
