Model 751H

Portable High Performance Zero Air System

The Model 751H is a portable, fully self-contained
source of high purity zero air for dilution calibrators.
It is ideal for use with sensitive analyzers in
ambient background and trace level applications.
Packaged in a wheeled, high density plastic case,
the Model 751H provides ultra-high purity output
with a warm-up time of 30 minutes.
The 751H includes a dew point sensor, a small,
powerful pump, scrubbers to remove SO2, NO,
NO2, O3 and H2S, plus high performance
scrubbers to remove CO and Hydrocarbons. The
regenerative heatless dryer removes water and
produces output with a dew point of -20ºC (up to
10 SLPM flow rate).

Rugged traveling case with
wheels and retractable handle
Dew point indicator
Long life scrubbers for SO2,
NO, NO2, O3, and H2S.
High Performance
CO/Hydrocarbon scrubber
Regenerative, heatless dryer
for maintenance-free water
removal
Automatic water drain
Once/year maintenance interval
Two-year warranty

The 751H features tank-less operation for real-time
pressurized output without “pulsing.” A
microcontroller cycles the regenerative dryer and
pressurized drain and features a short cycle
interval of 1 minute for high humidity applications.
