The Royal Filtermist is available in four sizes ranging from 275 - 1200 cfm, and its flexible design enables it to be mounted in a variety of ways, including: directly to the top of a machine tool, on a stand, or suspended from a factory ceiling. Maintenance and operating costs of the Royal Filtermist are minimal.
The low-cost Royal Filtermist effectively collects mist and smoke generated by all types of machines including:
The three-phase Filtermist motor must be wired in conjunction with a manual starter, which is not supplied by Royal Products. The recommended heater size is 1.25 times the rated motor amperage, based upon your plant’s operating voltage. We suggest you have a licensed electrician perform the wiring of the unit. Detailed instructions can be found in the installation manual that is supplied with each unit. As an option, Royal offers a complete starter box kit which includes all of the necessary hardware and wiring.
When installing a Filtermist unit, be sure to locate the intake in a position where it will collect mist, not splash. A common mistake is to locate the collection point too close to the cutting action, causing raw coolant and chips to be drawn into the unit. For example, the intake on a CNC lathe should be located near the tailstock-end of the machine, not over the chuck. Whenever possible, draw the mist across the enclosure from an area of heavy concentration to an area of lighter concentration.
For machines where the intake must be positioned near the cutting action, a deflector is often necessary. A deflector protects the intake from chips and coolant yet allows mist and smoke to pass around it for collection.
When evaluating the effectiveness of any mist collection system, two major aspects must be considered:
Independent testing has proven the Royal Filtermist FX Series to be very effective at handling large volumes of mist and highly efficient at dealing with the full spectrum of particle sizes found in typical metalworking mist concentrations.
While a typical metalworking mist concentration is made up of many different-sized particles, 80–90% of these particles are larger than one micron in size. Fewer than 10% of the particles are smaller than 0.5 micron in size.
In order to effectively eliminate mist, the Royal Filtermist incorporates a two-phase process:
The first phase utilizes the mechanical process of centrifugal impaction. This centrifugal impaction process is the heart of the Filtermist’s operating principle and it is highly effective at handling large volumes of mist.
The centrifugal impaction process is almost 100% efficient at handling particles larger than one micron, which make up the bulk of the mist. When considering a weighted average of the particle size in a typical metalworking mist concentration, overall efficiency of the impaction process is roughly 98%.
IMPORTANT — An after filter should not be used to compensate for blow-thru that could result from improper installation. If you have questions or concerns about your installation, please contact us.
The OSHA and NIOSH limits on airborne mist particles are currently set at 5mg/m3. It is believed that in the coming years this level will be reduced by a factor of ten to a new level of 0.5 mg/m3. The Royal Filtermist FX is so efficient that when equipped with an after filter, it easily meets not only the current limit, but even the stricter proposed limit.
In a recent test carried out by an independent contractor, a Mori Seiki SL75ML was fitted with a model FX-1200 Filtermist unit and after filter. Particle counters were set up to monitor the air at three locations during machining — the ambient shop air, the Filtermist intake, and the Filtermist exhaust. The test results confirm that the Filtermist easily meets the challenge. Particle concentration levels at the Filtermist exhaust were well below 0.5 mg/m3. In fact, the air at the Filtermist exhaust was four-times cleaner than the ambient shop air!
|LOCATION||CONCENTRATION (mg / m3)|
|Ambient Shop Air||0.75|
|FX-1200 Inlet||8.0 - 10.0|
IMPORTANT — The Royal Filtermist is designed to help your shop meet current and future air quality standards. It must be understood, however, that there are many variables involved in controlling shop pollution and we cannot guarantee that the Filtermist alone will prevent occupational diseases to workers. It is your responsibility to establish an effective overall industrial hygiene program designed to comply with OSHA and NIOSH standards.
Royal Products will issue full credit on any Royal Filtermist unit returned within 45 days of the purchase date if the customer is not completely satisfied with its performance.
