CHOOSING THE CORRECT FILTERMIST UNIT

The Royal Filtermist is available in four sizes, based on throughput

capacities: 300, 575, 900, and 1200 cfm. Royal Products maintains a

database with specifications for many different machine tools, and we

recommend you contact one of our applications engineers for your

specific sizing requirements.

For those who would like a general rule of thumb, we recommend using

the following formula to obtain a rough idea of your requirements:

Filtermist Size = Internal Enclosure Volume x 5

For example, suppose you have a small CNC lathe with an internal work

envelope measuring 5ft. wide x 3ft. deep x 4ft. high. Multiplying 5x3x4,

we see that the machine has an enclosure volume of 60 cu. ft.

Multiplying 60x5 we see that 300 cfm is required, so we’d choose the

model FX-300.

Although this rule is very simple, it is handy for determining the general

size requirements.

If you are not sure which unit to use, please contact your local

Royal Filtermist Distributor or one of our applications engineers.

Sizing Units

Grinding

Grinding applications can sometimes be more demanding than typical turning and

milling applications because grinding produces fine dust particles that become

entrained in the mist stream. Over time, this dust can accumulate on the drum pads,

resulting in the need for more frequent maintenance. If regular maintenance is not

performed and a significant volume of solid matter builds up in the drum, balance and

vibration issues may arise.

A simple way to overcome the problems associated with grinding dust is to fit

the Filtermist with a cyclonic swarf separator. The separator mounts below the

Filtermist unit and uses cyclonic action to separate out the solid matter, leaving the

drum free to process the mist and preventing buildup on the pads. A valve on the

bottom of the unit facilitates drainage.

Royal Products recommends using a cyclonic swarf separator for all

grinding applications.
