XIV. Filter Efficiency Gauge Mounting Instructions
Mounting Instructions
Gauge Reading Instructions
1. Select a location free from excessive
vibration and where ambient temperature
is between 20 F to 120 F (-6.7 C to 49 C).
You can mount gauge up to 8’ away from
static pressure tube. Gauge bracket can be
mounted to stand gusset for easy reading.
2. Mount brass static tube in plenum with tip
pointed into air stream. Use included mount-
ing bracket and sheet metal screws if interior of
plenum is not accessible. Refer to the drawings for
location of brass static pressure tube. Use 13/32”
drill bit for hole.
3. Put gauge through supplied mounting plate with
pre-cut 2 5/8” hole. Put the two bolts from gauge
box through front of gauge. Put metal brace from
gauge box against plate back with gauge bolts
through brace to hold gauge tight against plate. Put
supplied nuts from gauge box on bolts and tighten.
4. Mount plate with gauge to appropriate surface.
If mounting to stand, user must drill a hole and
supply hardware attachment. Connect clear tubing
from brass static pressure tube to port labeled “+”
on the back of the pressure gauge. Make sure
tubing is not crushed or kinked along its entire
length. Cut shorter if necessary.
Before you insert brass static pressure tube, use a marker and
mark top of brass nut where tube will be in the up position so
when you position tube or tighten it, you’ll know where tube is
pointing.
1. Gauge may need to be zeroed. Follow the instructions provided with pressure gauge.
2. Take the initial reading with cleaned filter(s) and the typical number of blast gates
open in normal operation.
3. Always read the gauge with the same number of gates open. The more gates open,
the higher the pressure reading on the gauge.
4. When the gauge rises to 3”, it’s time to clean your filter(s).
After many cleaning cycles, a filter’s pressure will rise after each cleaning.
An older filter does not get as clean as a new filter.
