FILTRATION
Ensure PNEUDRI is protected with the correct pre- and after-filtration with the flow directional arrows correctly
aligned with the dryers flow path.
It is recommended that each dryer bank has its own independent filtration. Size 0220 OIL-X filters should be
used on banks of up to and including 5 columns; size 0405 OIL-X filters should be used on banks of 6 columns
and above.
PRE-FILTRATION
This must be positioned as close to the PNEUDRI inlet as possible. domnick hunter grades 'AO' (3) and 'AA'
(4) pre-filters must be fitted upstream of the inlet to prevent contamination of the desiccant beds.
In cases of extreme contamination, a domnick hunter Water Separator (5) (WS grade) should be incorporated
into the system.
AFTER-FILTRATION
A domnick hunter grade 'AR' (6) filter must be fitted downstream of the dryer to prevent dust carryover. Heat
Regenerative (DHE/DHS Models) must be fitted with high temperature 'TS' grade elements.
BYPASS LINE AND VALVE
It should be noted that the use of a bypass line (7) allows wet and untreated air into the system. For continuous
duty, a standby dryer should be installed. Even with multi-bank systems, this means that only one more bank
is required, which offers the benefit of 100% standby.
SHUT-OFF VALVES (ISOLATION)
Shut-off valves (8) must be fitted to the inlet and outlet pipework of each dryer bank and are used during the
"Bring online/Take offline" procedures and during maintenance periods.
