Maintenance and Techniques for Cleaning the
P-Series
Air-Trap
In some operations, particulate matter can move from
the HVAC unit through the drain line and into the
P-SERIES
Air-Trap
. The accumulation of particulate
matter in the trap may cause the trap to operate less
efficiently or fail. Therefore, a means to remove the
accumulated debris is required. A stainless steel filter
screen (
Figure 1
) over the drain inlet or a
Union-Strainer™ (Figures 7 & 8)
within the drain line
extends the time between maintenance. Install the
Union-Strainer™
upstream of the
Air-Trap.
There are several other options for cleaning. Option 1,
is to use the ½-inch cleanout port in the trap housing.
This will allow insertion of a water or air hose for
washing or blowing away material that may be
hampering operation of the trap. See
Figure 3
.
Option 2, shown in
Figure 7,
is to isolate the
P-SERIES
Air-Trap
from the main drain line by
installing unions that allow
Air-Trap
removal for
replacement or cleaning.
The best way to reduce maintenance is to install a
Des Champs
Union-Strainer™
upstream of the
Air-Trap,
(See
Figure 8
)
.
The
Union-Strainer™
is
also a convenient way to prevent unwanted creatures
and objects from entering the terminus of the drain line,
like snakes, rats, lizards, insects, and other
miscellanious items like, rocks, screws, and nuts.
The
water flow is in direction of arrow shown in
Figure 8
,
with the strainer cup oriented to capture debris within
the cup.
Des Champs Technologies also offers engineered
traps for positive plenum pressure above 12 inches in
WG.
Figure 4
is a cut away view of an engineered
trap showing a cleanout port and the cylindrical float
that rises off the seat when condensate begins to
accumulate in the trap. Engineered
Air-Trap
s are
designed for applications above the 12 inches of
positive pressure of the standard P-Series
Air-Trap
.
The Engineered
Air-Trap
can withstand positive
pressure up to 50” of WG or greater.
Caution, do not
puncture the Float Valve.
