Maintenance
The mist collector can operate for long periods without maintenance. The maintenance period will
depend on the type of oil, coolant & debris in air stream. Inspect the unit after 3 months, 6 months
& 1 year to establish the maintenance interval.
Some coolant concentrates will congeal requiring the 1st stage mechanical separator elements and
the 2nd stage agglomerator filter to be manually cleaned/washed. If this is frequent, suggest
installing the optional On-Line Cleaning System.
Debris / swarf can be high on cast iron machining and grinding. If filter cleaning is frequent,
suggest installing the On-Line Cleaning System.
The mist collector has one magnehelic gauge measuring the pressure drop on 4th stage HEPA
filter. Should the gauge reduce to near zero, this indicates no air flow going to HEPA filter, check
filter stages 1 to 4 and chip strainer.
HEPA filter replacement:
Replace when magnehelic pressure gauge
reaches the red zone.
Note:
If filter stages 1 – 3 or chip strainer are plugged, no air flow
will go to 4th stage HEPA filter and pressure reading can
reduce.
