Setting Up AQUATRAN Model 3/40 Operator's Manual

Carrier Gas (Nitrogen)

The AQUATRAN Model 3/40 requires a Carrier Gas that is 99.7% nitrogen.

Compressed Air Supply

The AQUATRAN Model 3/40 requires a supply of clean, dry compressed air for chamber RH generator that
provide moisture as test gas. The supply pressure must be between 72 and 95 psig (5 to 6.55 Bar) at a
maximum flow rate of 0.88 CFM (25 LPM). The compressed air purity must meet or exceed ISO 8753-
1:2010 [1:3:1]. Each instrument requires a local compressed air regulator. A compressed air regulator is not
supplied with the instrument.

Gas Distribution System

Each instrument ships with a local regulator/isolation device (called a Regulator Tee) that can be used to
connect the instrument to a common Carrier Gas distribution system. Figure 2-4 illustrates how a gas
distribution system for multiple instruments can be created using the provided Regulator Tee.
When using a compressed gas cylinder, consideration should be given to the impact cylinder replacement
will have on operational efficiency. Interruptions to the gas supply when a cylinder is changed (or goes
empty) will have an adverse effect on any active tests. Cylinder manifolds that provide an uninterrupted gas
supply during cylinder replacement are available from many gas suppliers.
