The GilAir pumps (including GilAir-3) have one of the largest user bases of any air sampling pump worldwide. This reliable 3 liter per minute air sampling pump has automatic constant flow assuring sampling is maintained within +/- 5% of the initial set point. Setting the flow rate on the GilAir-3 is a simple process that requires no special adjustment tool so you spend less time configuring pumps.
Automatic constant flow — the most important feature of any sampling pump — is standard on all GilAir-3 pumps. It assures flow is maintained within 5% of the initial set point, even with varying back-pressures from flow restrictions or buildup of material on the filter. GilAir-3 pumps are suitable not only for conventional pull-through sampling media but also for bag sampling and other pressure applications.
