The Gilian® 3500 & 5000 are industry leaders in back-pressure performance, reliability and ease-of-use. These pumps offer flow rates up to 3500 & 5000 cc/min respectively. And thanks to several advanced features, these pumps overcome the main causes of sampling errors – saving you time and money. The air flow display holds calibration for 30 days, even with atmospheric changes. While Gilian air sampling pumps are known for their strength,the back-pressure capabilities of the Gilian 5000 are the highest in the industry for any personal sampling pump.

Fast-charge NiMH battery ends 'memory' problems.
With the 3500 & 5000 there is less risk of lost samples due to battery failure. Both models incorporate a nickel-metal hydride (NiMH) battery which, unlike a NiCd battery, doesn’t suffer from 'memory' problems. So there’s no hidden loss of battery capacity, no shorter-than-expected run time and no need for special battery maintenance. You use our standard charger and get the same, highly predictable life, charge after charge.

When the display indicates a 'full' battery, that’s exactly what the pump delivers. Plus, the indicator more accurately displays remaining life throughout the sampling period. You get faster charging too. The NiMH battery charges in under four hours. And you won’t be hampered with special storage or disposal requirements, since the NiMH battery is friendly to the environment.

Power equals higher flow rates and higher back-pressure capabilities.
Gilian 3500 and 5000 Low Flow AdapterThe Gilian 3500 & 5000 provide automatic constant flow from 700 cc/min to 3500 cc/min and 800 cc/min to 5000 cc/min. When used with a low flow module, they also handle low flows from 20 to 750 cc/min and 20 to 800 cc/min under constant pressure control, such as required for multi-flow sorbent sampling. These pumps offer significantly higher back-pressure capabilities than competitive pumps thanks to a more advanced pneumatic design and a more powerful power source. As a result, dense ­particulate buildup on the filter, such as with dusty environments is far less likely to trigger premature pump shutdown and an incomplete sample. See the chart on the following page for back-pressure information.

Programmable automatic restart when faults occur.
Both the 3500 & 5000 have an intuitive automatic restart feature that will attempt to save a sample should a fault occur. If the filter becomes clogged or tubing pinches not allowing air to pass, the pump will shut down and attempt to restart every 3 minutes for up to 30 minutes. This option is selectable on the 5000.

Four-button design is easier to understand and operate.
These pumps are easy to understand and configure, just four keys control everything. There are no codes to enter or difficult key sequences to remember. Operation is simple, intuitive and less prone to error. So you’re up and running in less time. To secure your settings from tampering, both the 3500 & 5000 have a lockable keypad after setup and calibration.

Easy to calibrate and set-up.
Air flow settings and calibration of the flow rate display are done through the keypad, requiring the use of only an air flow calibrator. This means you can set up your pump and begin sampling quickly. The pumps also perform an automatic self calibration of internal temperature and pressure measurement when initially placed in the run mode and whenever the ambient temperature changes by more than 3°C during sampling.

Live flow display confirms proper pump operation.
Monitoring the pump for proper operation is easy. A large digital display continuously cycles to show flow rate, sample run time and total volume sampled. You receive immediate, real-time feedback, including live flow, not just the flow setting which quickly alerts you to any sudden changes in flow rate.The wearer can stop the pump, such as for a break and the display remains active. After 75 minutes, the pump automatically turns off the display if there’s no activity but retains all sample data.
