Leland Legacy
5 to 15 L/min


Orderable Items 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.
The Leland Legacy air sampling pump is CE marked. It is not UL Listed for intrinsic safety.



 

High flows from 5 to 15 L/min
Achieve flow rates that you couldn't reach before when using a personal sample pump. The Leland Legacy provides the high flows and long run times of a vacuum-style pump in a compact, portable, and battery-operated sampler within specified back pressure range. NOT for applications requiring instrinsic safety.

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.* Leland Legacy is ideal for 24-hour indoor air studies and unattended ambient air sampling.

* Leland Legacy is not recommended for high back pressure applications such as asbestos clearance sampling.

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
  • IMPACT Sampler (PM2.5 or PM10) at 10 L/min
  • For extended run times, the pump may be operated while attached to the approved charger.

Results obtained using a new pump and new fully charged battery. Pump performance may vary.
Back pressure on PTFE filters can vary within the same lot. Maximum operating temperature is 464 F (240 C) based on support ring.

Low Levels
Longer runs at higher flows provide more sample for the enhanced sensitivity required for measuring low concentrations, particularly in indoor air environments.

Low Noise
With the noise-reducing case accessory, the Leland Legacy can operate at 10 L/min and 12 inches water back pressure with a noise level of only 52 dBA.**

** Measured 3 feet (1 meter) from pump operating at 10 L/min without media

Advanced flow control
The patented (U.S. Patent Nos. 5,892,160) internal flow sensor measures flow directly and acts as a secondary standard to constantly maintain the set flow. Set flow is achieved immediately at start-up and flow calibration is automatically maintained by built-in sensors that compensate for differences in temperature and atmospheric pressure during sampling.


Flexible programming
  • Manual three-button operation
    No tools needed. Simply use the Leland Legacy built-in keypad to set, calibrate, and sample! Real-time sampling parameters are available at the touch of a button.

  • PC programmability
    The ultimate in pump scheduling and record keeping. Use Leland Legacy with your PC and DataTrac for Leland Legacy Software to create complete running sequences, download sampling and calibration data, and generate sampling reports for ISO 9000, quality programs, and occupational health and safety management systems. DataTrac Software for Leland Legacy is included in the 5-pack kits and sold separately.

Performance Profile
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.

The Leland Legacy Advantage

Collects more sample
High flows and long run times greatly increase the amount of particulate matter collected when sampling low levels. This enhances the usefulness of the data for environmental health and epidemiology studies.

Designed for indoor environments
Noise, size, and weight are minimized relative to the high flow range.

Downloadable history
Critical sampling parameters are retained in memory during the sampling period and can be downloaded for record keeping.

 

Leland Legacy and Sioutas Impactor*
Suitable for use with the Leland Legacy Pump at 9 L/min, the Sioutas Impactor separates airborne particles precisely into five size ranges from ultrafine to PM2.5. When used with PTFE filters, the Sioutas Impactor is highly efficient at collecting particles without using impaction grease or coated substrate and at retaining unstable compounds for size-fractionated chemical analysis. The performance of the Leland Legacy pump with the Sioutas Impactor has been verified through EPA-ETV.

ETV LogoLeland Legacy and Sioutas Impactor Receive ETV Verification
U.S. EPA Environmental Technology Verification (EPA-ETV) is a program that furthers environmental protection by accelerating acceptance and use of improved, cost-effective technologies through performance verification. EPA-ETV tested the performance of the SKC Leland Legacy Sample Pump with the Sioutas Impactor. For a verification report, visit the AMS Center at http://www.epa.gov/etv/vt-ams.html.

The SKC Leland Legacy and NUATRC

The Leland Legacy was developed in partnership with the Mickey Leland National Urban Air Toxics Research Center (NUATRC) to further advance personal exposure measurement.

Established by Congress in the Clean Air Act Amendments of 1990 (CAAA), the non-profit Leland Center is responsible for investigating public health risks posed by air toxics to urban populations. The Leland Center is a private/public research partnership that brings together corporate, academic, and government scientists to develop a sound peer-reviewed air toxics research program. This program is jointly supported by the private sector and the U.S. EPA.
