GilAir Personal Air Sampling Pumps

These reliable 3 and 5 liter per minute air sampling pumps have an automatic constant flow, assuring sampling is maintained within ±5% of the initial set point. Setting the flow rate on the GilAir-3 & GilAir-5 is a simple process that requires no special adjustment tool so you spend less time configuring pumps.

Automatic constant flow is standard on all GilAir-3 and GilAir-5 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 and GilAir-5 pumps are suitable not only for conventional pull-through sampling media, but also for bag sampling and other pressure applications.

The GilAir-3 and 5 are available in 3 models:


Straight-forward and easy to use


Provides an elapsed-time clock display


Enables a timer which can start or stop the pump at preset time intervals, or program a delayed start
