Balston Coalescing Compressed
Air Filters protect your equipment
and delicate instruments from the
dirt, water, and oil usually found in
compressed air. Balston Coalescing
Filters remove these contaminants at
a very high efficiency up to 99.99% for
0.01 micronparticles and droplets.
Liquid releases from the filter cartridge to an automatic drain as rapidly
as it enters the filter. This allows a
Balston Coalescing Filter to continue
removing liquids for an unlimited
time without loss of efficiency or flow
capacity. Select 1/4” to 2” line filters
come with a lifetime (20 year) warranty which guarantees the product
against defects and other failures.Product Features:
• Remove 99.99% of 0.01 micron • Service flow ranges from a few
particles of oil, water, and dirt
SCFM to 40,000 SCFM
from compressed air and other
• Remove trace oil vapor with
gases
adsorbent cartridges
• Continuously trap and drain
• Lifetime warranty (20 year) with

Balston Filter Cartridges
Balston provides two grades of coalescing filter cartridges, Grade DX and Grade BX. Singly or in tandem,
these filters satisfy allrequirements for removing liquid
and solid contaminants from compressed air. Balston
also has an activated carbon adsorbent CI-type cartridge
for the removal of trace oil vapors from a compressed air
line. The activated carbon cartridge is Grade 000.

Filter Cartridge Description
General purpose
applications such as plant
compressed air

Single stage filtration. Use a Grade DX filtercartridge

Instrument air and other
critical air requirements

Two stage filtration is necessary. Use a
Grade DX followed by a Grade BX filter cartridge. As a general rule, a Grade BX filter
cartridge should not be used alone.

Removal of trace compressor oil vapor

How to Select the Filter Cartridge and
Housing

For rare instances where even a trace
amount of oil vapor can cause aproblem,
three stage filtration is necessary. Use a
Grade DX followed by a Grade BX, and a
type CI cartridge.

1

Decide which grade(s) of filter cartridges fits the
application (see selection boxes at left).

2

Select the filter housing with a port size equal to the
line size where the filter is to be located.

3

For a new installation in which the line size has yet
to be selected,determine the gas flow rate and
pressure at the point where the filter will be located,
and then refer to the flow chart on the reverse side
of this data sheet. NOTE: The filter port size must
be equal to or larger than the line size (when specified).

Build your own customfilter assembly using the
guideline matrix on Page 16 and specify your
model number. Example: 1/2” filter with DPI and
Auto Drain with Grade DX Filter = 6004N-01A-DX.
Each assembly is shipped with the filter cartridge installed. To order additional filter cartridges, indicate
the model number of the cartridges, and the grade.
Examples 050-05-DX, 050-05-BX. The grade used
