Model G0944/G0944HEP (Mfd. Since 03/21)
SECTION 4: DESIGNING A SYSTEM
General
Always guard against stat-
ic electrical build up by
grounding all dust collec-
tion lines.
The Model G0944/G0944HEP works quite well as
a point-of-use dust collector, or for collecting dust
from up to two machines simultaneously.
Tips for Optimum Performance
•
Avoid using more than 10' of flexible hose on
any ducting line. The ridges inside flexible
hose greatly increase static pressure loss,
which reduces suction performance.
•
Keep ducts between the dust collector and
machines as short as possible.
•
Keep ducting directional changes to a mini-
mum. The more curved fittings you use, the
greater the loss of suction at the dust-produc-
ing machine.
•
Gradual directional changes are more effi-
cient than sudden directional changes (i.e.
use 45° elbows in place of 90° elbows when-
ever possible).
•
The simpler the system, the more efficient
and less costly it will be.
Always make sure there are no open flames
or pilot lights in the same room as the dust
collector. There is a risk of explosion if too
much fine dust is dispersed into the air with
an open flame present.

The air flow test probe is located 1.5x duct diameter upstream
from the air inlet. Test pipe length is a minimum of 10x duct
diameter.
