Innovation Delivered:  The ultimate personal air sampling pump delivering enhanced performance, greater versatility, and superior design and comfort.

The Widest Flow Range of Any Personal Air Sampling Pump

Personal Industrial Hygiene Air Sampling PumpThe GilAir® Plus features wide dynamic flow and pressure ranges to address all personal air sampling methods with flow ranges between 20 and 5,100 cc/min. With patent pending QuadModeSM air sampling technology, the GilAir Plus can perform both high-flow constant pressure and constant flow (450-5,100 cc/min) and low-flow constant pressure and constant flow (20-499 cc/min) with a single pump without external adaptors. It's like getting two pumps in one.


Unmatched Versatility

  • Samples particulates, vapors, gases, and metal fumes
  • Works with all common sampling media
  • Multi-language capability: English, Spanish, French, Italian, Dutch, Portuguese and German
  • Outlet port for bag sampling



PC ApplicationHigh Performance

GilAir Plus is a smart air sampling pump that provides ambient or standard temperature and pressure corrected display (STP model) and data-logging for up to 16 sampling events (STP and Datalog model). The pump has high back pressure capability of up to 40" H2O in high flow and up to 40" H2O in low flow. An automatic self check system ensures sample accuracy. In the event of a fault condition, the pump's selectable automatic fault recovery feature attempts to restart the pump up to 10 times every 3 minutes to determine if the fault condition has been cleared.


Easy-to-read, backlit displays  air sampling pumpsEase of Use

An intuitive menu, keypad interface and large, easy-to-read back-lit display makes adjusting pump settings quick and easy. Once the pump is set up, the keypad can be locked to prevent tampering. Convenient and innovative SmartCalSM feature provides automatic pump calibration.


Compact Personal Air Sampling PumpErgonomic Design

One-third smaller than traditional personal air sampling pumps and weighing less than 21 oz. (595 g), the GilAir Plus provides superior operator comfort. An integrated belt clip securely attaches the pump in a horizontal position, allowing workers a full range of motion to perform a wide variety of tasks without interference or discomfort.



Multi-pump DocksThe GilAir Plus dock provides charging and communication functions for the STP and data-logging models. Once docked, the PC application allows users to review datalogs, generate sampling reports, manage sampling programs, and create pump set-up profiles that expedite deployment of large pump fleets. The SmartCalSM feature uses the dock as a communication link between appropriate calibration devices and the GilAir Plus. SmartCalSM automates calibration and records pre and post sample calibrations in the pump's datalog.

Barometric Pressure Compensation

When sampling at altitudes of up to 8,000 feet above or 8,000 feet below sea level, GilAir Plus has the capability of automatically correcting the flow rate for altitude changes to maintain constant flow accuracy of +/- 5% over this barometric pressure range. This feature permits GilAir Plus calibration at ground level and sampling at high elevations or deep mines without loss of flow accuracy or the need to calculate and use manual correction factors. GilAir Plus is the only personal air sampling pump with this capability.
