INTRODUCTION.
1.1
The 737-1 (one-liter per minute) pure air generator is unique in the 737-series of
pure air generators. It is the only unit which is completely self-contained. All
components of the system, the air source and purification system, are within one
cabinet.
1.2
Incorporating all components within one enclosure limits the maximum output of this
instrument to one-liter per minute. Since all of the components must be able to
accommodate the air volume and perform the purification functions as well, there is
a compromise in component size.
1.3
The user must be aware of this limitation in capacity and select only those
applications whose requirements do not exceed this limitation. FAILURE TO DO
SO WILL COMPROMISE THE PURITY OF THE AIR ISSUING FROM THE UNIT.
1.4
When application is made to those situations which remain within the one-liter per
minute capacity, the air quality will be equal to any and all of the larger 737-series
pure air generators.
1.5
The 737-1 pure air generator is available either in bench-mounted or rack-mounted
units. All components are common to both and are readily interchangeable.
1.6
Figures 1 thru 5 are referenced to the bench-mounted units, Figures 6 thru 8 refer
to the rack-mounted units, and Figures 9 thru 11 are common to both.
1.7
The SOURCE SELECTOR valve, Figure 1 (5), and the EXTERNAL SOURCE
bulkhead connector, Figure 2 (4), are not a part of the rack-mounted units since the
use of "house" air as a source for this unit is very uncommon. Both of these
components, shown in Figure 10, should be ignored when addressing the rack
mounted systems.
