Oil Mist Collectors FAQ
Q. What are the features to look for in an oil mist collector? A. The first consideration is wet vs. dry operation. A dry oil mist collector
consumes single-use filters and when they’re saturated, you replace them.
Operations and disposal costs are high, and continuous. A wet oil mist collector
has cleanable filters that won’t degrade over time. Also, look for an oil mist
collector that allows you to re-use the oils or coolants collected. A low pressure
design (10” or less w.g.) minimized energy use. Q. How important is it that an oil mist collector handle smoke? A. A dedicated stage to handle smoke is important: this is best accomplished with
a DOP/HEPA filter on the final stage. If you don’t need this capability now, (and don’t
want to pay for it) find an oil mist collector that will accommodate a retrofit later. Q. How efficient does an oil mist collector need to be ? A. 99% efficiency at 2 microns is the benchmark standard for an oil mist collector
because it addresses the vast majority of air quality regs, and is applicable to oils,
synthetics and semi-synthetics. Q. Can an oil mist collector be portable? A. Where flexibility is important, make sure the oil mist collector can be used
anywhere there’s a water source by simply putting it on a castered frame. Q. What kind of filter is used in an oil mist collector? A. The most effective filter for an oil mist collector is a Kimre 13-layer polypropylene
mesh filter media, which is standard with the OM/1. It withstands 180 degrees,
is chemically inert, and won’t degrade from exposure to jagged fines and other
contaminants. Maintaining the stage 1 filter allows the 2nd stage “workhorse”
filter to perform at extremely high efficiencies, for long periods of time. Q. What kind of filter cartridges are used in an oil mist collector and
what maintenance is needed? A. Cartridges provided in the OM-1 oil mist collector are durable, easily accessible
for cleaning, and have performed for 20 continuous years – and longer. Q. How does the Tri-Mer oil mist collector compare with indexing fabric filters? A. Indexing fabric is useful where there’s one oil mist source, and mist quantity is small.
For multiple sources, a commercial oil mist collector is recommended. Q. Is there an oil mist collector with automated wash-down? A. Yes – and this is important, because in additional to initiating the cleaning cycle,
it will indicate when the lead pad (stage 1) should be removed and cleaned. The 2nd
stage is where the serious work is done in an oil mist collector; keeping stage 2 at
optimum efficiency is most important. Q. Does an oil mist collector require sound damping? A. It depends on the installation. 85 dba at 5 ft. is the requirement.
Tri-Mer engineers its oil mist collector to 80, so compliance is assured.
The key is fan design. 7500 cfm at 12” of pressure produces 95 dba at 5 ft.
and if this is the cfm required, it’s easily dampened with a sound attenuator
on the outlet side of the oil mist collector. Q. Can one oil mist collector accommodate multiple mist sources? A. A good oil mist collector accommodates many sources with just a simple
ventilation configuration, providing all mists are either water-soluble –
or none of them are.
