The personal-size Leland Legacy® air sampling pump offers flows from 5 to 15 L/min, PC-programmability, and up to 24-hour run times for personal or area sampling of low-level contaminants. The pump is ideal for use with impactors, low-volume PUF tubes, filter cassettes, and spore traps.

  • High flows from 5 to 15 L/min
  • Achieve flow rates that you couldn't reach before when using a personal sample pump
  • Long runs for 24 hours on one battery charge
  • Rechargeable lithium-ion (Li-Ion) battery pack provides 24-hour run times with impactors and other sampling devices with low back pressures.


Flow Range 5 to 15 L/min
Flow Control System Closed loop with internal flow sensor
Compensation Range 15 L/min at 5 inches water back pressure
10 L/min at 12 inches water back pressure
 5 L/min at 20 inches water back pressure
Accuracy Flow Rate: ± 5% of set-point after calibration to desired flow
Timing: 1 min/mo at 25 C
Atmospheric Pressure: ± 0.3 in Hg
Flow Fault If the pump is unable to compensate for > 15 seconds due to excessive back pressure, a flow fault icon displays and flashes, the pump enters Hold mode, and the pump retains historical data. Auto restart is attempted every 20 seconds up to 10 times. Adjustable with DataTrac for Leland Legacy software
Flow Control An internal isothermal flow sensor measures flow directly and continuously. Sensor readings are used in a flow monitoring algorithm to maintain calibrated volumetric flow. In addition, built-in atmospheric temperature and pressure sensors provide readings to correct volumetric flow for these parameters when they vary from point of calibration.
Tubing Requires 3/8-inch ID tubing
Display LCD, displays pump serial number, pump software revision level, flow rate, volume, temperature, atmospheric pressure, time of day, run time, and pump status, i.e., hold and run as well as Setup information
Volume Display Continually updated, based on corrected flow rate multiplied by sampling time. When volume exceeds 99,999 liters, the pump will continue to run normally but an O_FLO error will appear on the LCD.
Time Display Time of day in hours and minutes (12 or 24-hour clock) with AM and PM indicators
Timer Display Range 1 to 99999 minutes (69 days). If the run time exceeds 69 days, the timer display rolls over.
Operating Temperature Range 32 to 104 F (0 to 40 C)
Protect sample pump from weather when in use outdoors.
Altitude The pump can apply correction to volumetric flow during sampling for weather-related or altitude variations from the atmospheric pressure established at calibration up to at least 7500 feet (2286 meters) above and 5000 feet (1524 meters) below sea level.
Typical Run Time

24+ hours:

  • Sioutas Impactor at 9 L/min (approximately 13 inches water back pressure)
  • Low-volume PUF Tube at 5 L/min
  • DPS Sampler (PM2.5 or PM10) at 10 L/min
  • For extended run times, the pump may be operated while attached to the approved charger.
  • 8 L/min Respirable PPI
  Results obtained using a new pump and new fully charged battery. Pump and battery performance may vary.
