Delmonox Replacement Filter Elements for all models
Inlet air enters a three-in-
one prefilter E where solid
particles, liquid oil and water are
removed. The prefilter changes
color to signal element replacement.
An automatic drain D continually
discharges the separated contaminants.
How G Series Breathing Air Units Work
Filtered air enters one of two
desiccant towers via a four-way
valve G. The twin desiccant towers
remove water vapor. Calibrated
color change strips I indicate relative
humidity and monitor dryer
performance. An electric timer
(110V/75W NEMA Type I) switches
air flow from vessel A to vessel B on
a timed cycle. A small portion of the
dried air (purge air) is used to
regenerate the offstream vessel.
A catalyst C converts carbon
monoxide to carbon dioxide. (A
carbon monoxide monitor and
alarm are available as an option.) An
activated charcoal filter F removes
objectionable tastes and odors. An
afterfilter removes any remaining
particulates. Grade D breathing air is
then supplied to the system.
Product Options:
- Carbon monoxide monitor
- 12VDC Control
- Cart-mounted
- Manufactured to meet NEMA 7 (Class I, Division II, Group D) standards
- High-efficiency prefilter for use with oil-flooded rotary screw compressors
- Electronic automatic drain valve
Sizing Example
In a sandblasting operation, three
workers require 6 scfm each for their
Type CE respirators. The air system
pressure is 100 psig.
The maximum required breathing air
flow rate is 3 x 6 or 18 scfm. From the
Model Selection Chart, using 100 psig
operating pressure as a guide, select a
purifier with an outlet flow that equals
or exceeds 18 scfm. Select model 3H10.
Additional air must be supplied at the
purifier inlet for operation of the dryer.
To estimate the required inlet air flow,
divide the maximum outlet air flow by
0.75. In this example, the required inlet
flow is 24 scfm.
