Pressure Gauge: How to Use it
This machine includes a recessed pressure gauge located in the lower base unit
directly below the fold-out loading door.
The pressure gauge has two functions:
1. Calibrate air pressure for effective dense packing (cellulose) and reducing the chance of
pushing drywall from the studs.
2. Troubleshooting machine production & coverage problems and assessing wear of airlock seals
for replacement.
The performance of your machine is related to the quality of airlock seals and its ability to achieve
higher pressures. The airlock seals trap compressed air inside airlock chamber (from blowers), and
provide required air pressure & volume for optimizing y
ou’re machines performance. When the
back-
pressure drops below 3.2 p.s.i. problems will occur.
When air is leaking past the seals, this ‘blow-back’ into the hopper will cause the following
problems:

Poor quality dense packed walls allowing settling in wall cavities over a prolonged period.

Low production rates
for open blow, caused by ‘blow-back’ bridging effect inside hopper.

Poor material coverage (yield) due to loss of conditioning from low air volume & pressure.

Hose plugging due to lower pushing effect of low pressure.
How to use:
Pressure gauge has a graduated scale (0-
15 p.s.i.) with a ‘green’
colored section (3.2 p.s.i.) recommended as minimum requirement
for optimal performance.
This is the pressure recommended for effective dense packing
and acceptable machine performance for open blowing distances
over 150 ft.

Dense pack adjustment:
1. Turn blower on ( no feed).
2. Back pressure system by blocking end of hose with
hand and read pressure gauge.
3. Have assistant turn blower speed up/down until the
gauge
registers in green’ section of gauge (3.2 p.s.i.).
(Note: the blower control will need to be adjusted higher as airlock seals wear and lose
efficiency).

Checking airlock seals:
1. Turn blower on ( no feed).
2. Back pressure system by blocking end of hose with hand and read pressure gauge.
3. Turn blower speed on high. If minimum of (3.2 p.s.i.) cannot be achieved when blowers
are adjusted on high, the airlock seals may be damaged or worn and will need to be
replaced. See page 12 of owner’s manual. (Note: longer blowing distances and higher
elevations will require higher pressure when evaluating airlock seal quality. Properly
installed ‘new’ seals, after short wear-in period, should achieve pressures over 3.5 p.s.i.)
