Q:
Can mist collection equipment handle high-pressure
coolant situations?
Yes. The patented
Eliminatør was designed with High Pressure (HP) coolant
in mind. Also ensure that the mist collection system is
sized adequately (CFM) to draw mist to the collector and
away from your door opening.

Q:
What is CFM?
CFM = Cubic Feet Per Minute.
This is the volume of air that can be moved. CFM of a
piece of air filtration equipment is based on the capacity
of the blower at a specified pressure or resistance.
Example: 2000 CFM at 1"
of WG means that you can expect 2000 CFM from your system
with a maximum of 1" of resistance. The more resistance
through your system, the lower the Actual or Delivered
CFM.

Q:
What causes resistance to air flow?
Filters in your collection
system provide resistance based on the size, efficiency
and material of the filters. Among other factors, resistance
in the system is caused by the type of ductwork, the material
the duct is made of, the length of the duct and how many
elbows and turns the ducting has.

Q:
What is FPM?
FPM = Feet Per Minute.
This is the velocity (speed) that air is moved.
a. Conveying
Velocity is how fast air is moved through the
ductwork.
b. Pick Up Velocity
is how fast the air moves at the face of the duct hood
or duct intake.

Q:
What if my shop has
many open and/or old machines that do not lend themselves
easily to ducting?
Though "Source Capture" (ducting to the source of the mist/smoke/dust) is preferred, at times this is impractical or cost prohibitive. For this type of condition, it is possible to "Free Hang" (hang air filtration equipment from your ceiling or walls with no ductwork attached) to filter the ambient air. This is not a perfect solution and it is significantly less efficient than the "Source Capture" method, but also significantly better than doing nothing. Note that size and the number of units required is based on the type and amount of contaminants in the air.

Q:
What are the typical
types of mist collection equipment?
a. Media Type:
This type of equipment comes with cleanable and/or replaceable
filters manufactured from a variety of materials and in
a variety of efficiencies. In addition to mist collection,
these can frequently be modified to meet unique conditions
including for the capture and removal of smoke and fumes
and odors and dust.
b. Centrifugal
Type: This type of collector has a finely balanced
rotating drum that acts as the blower as well as filter.
It is compact in size, but typically is limited to about
1200 CFM maximum and frequently requires prefilters due
to type of coolants being used and the type of application
(i.e.: iron machining; aluminum machining; grinding).
c. Electrostatic
Precipitator (ESP): The ESP is highly efficient
for small particulate, such as smoke, but requires a high
amount of maintenance to maintain it's air cleaning efficiency,
otherwise it simply exhausts dirty air back into your
plant environment. These operate by ionizing particles
(mist, smoke, dust) and collecting the particles on a
collection cell.
