Introduction
1
The Zero-Air Generator (ZAG) is a simple, light-weight, self-contained system capable of producing
high purity, particle free, dr y air at up t o 18 liters per minute. It is designed to r eplace gas cylinders as a
source of calibration standard. T he ZAG can be used with stationar y analyzers, but its portability
makes it especially well suited for use with remote m onit o r ing sites and mobile testing facilities.
Operation is very simple. Ambient air is brought into the Zero-Air Generator where it is com pr essed
and then purified using a combination of membranes, adsorbents, and f ilters. The only outside item
that needs to be supplied is AC power.

Maintenance requirements are minimal and easy to perfor m. There are two desiccant canisters, one of
which needs to be replenished periodically; under normal use, it will last up to six months. T he ot her
desiccant canister contains a catalyst that is not consumable. The only other regular maintenance is to
replace the particulate filter per iodically. All ot her com ponents in the system are designed to provide
years of trouble-free service.
The Perma Pure ZAG is ideal for use with the following monitors:
! Nitrogen oxides (NO
! Carbon monoxide ! Ozone
) ! Sulfur oxides (SO x)
! VOC’s (except methane)
x
Consult Perma Pure for other m onit o r ing applicat ions.
The rugged design of the ZAG makes it ideal for field use. The components are protected inside a
hard plastic enclosure, which is roughly the size and weight of a fishing tackle box. The ZAG takes up
a minimal amount of space and is very easy to start up.
In addition to its convenience, the ZAG is also a safe and cost- effective source of high pur it y air. G as
cylinders are heavy, bulky, and under high pressure. Extreme caution must be exercised when
working with them. In addition, these cylinders are very expensive and can cause storage problems.
The only operating costs associated with the ZAG are electricit y (about $75/ year if run continuously)
and replacement desiccant. Depending on zero air consumpt ion, it will normally pay for itself within 12
months.
