AS-300 Pump (D.C. input)

The Spectrex 300 series gas pumps use a high quality "tape-deck" type D.C. motor and provide extremely low power, high efficiency pumping for gases. They use a special, formed "viton" diaphragm and highly stable mylar valves. A specially designed mechanism provides variable stroke which can be set with extreme precision. As the motor can take from 3 to 15 volts D.C., the combination of correct stroke and voltage produce a highly efficient system.

AS-300

FEATURES

  • Wide flow range 0-3 LPM
  • Variable stroke
  • 3-15V D.C. operation
  • Low current
  • Over 10,000 hour operating life
  • Mounts in any orientation
  • Inert materials, mylar, delrin and "viton"
  • Weight: 6oz.


APPLICATIONS

  • Industrial hygiene
  • Gas analyzers
  • Medical instruments
  • Environmental instruments
  • Particle detection
  • Nuclear instruments


STABILITY

Both models have extremely stable flow, and long term tests have consistently shown less than 3% flow change over 7-day sampling periods.
