Mistresa High-temperature Mist Compatible Series ( CRMH )

The Mistresa collects oil mist that is generated by machine tools in machining worksites to maintain a comfortable working environment. Removing oil mist from the air helps protect worker health, and also stops secondary negative effects such as oil accumulating on the floor that can cause falls.
The high-temperature mist-compatible CRMH is available in filterless and filter versions, so that customers can select the best option for their application.

About Multi-Select

Motor output from 0.2 kW to 2.2 kW, two types of parts on the filter box side, three types of parts on the main unit side, and horizontal and vertical options mean we can deliver, in a short time frame, any one of 60 combinations optimized for your company's needs.
"The perfect Mistresa product for every customer": A mix and match mist collector.
Front Parts
Front Demister
Front Demister
Suctioned air containing mist hits the collision plate, and the mist drops down and forms droplets. These large mist droplets adhere to the front demister and are discharged through the drain.
(Mainly compatible with water-soluble cutting fluids)
Front Filter
Front Filter
Suctioned air containing mist hits the collision plate, and the mist drops down and forms droplets. These large mist droplets adhere to the front filter and are discharged through the drain.
(Mainly compatible with oil-based cutting fluids)
Back Parts
Tapered Tube
Tapered Tube
Fine mist that passes through the front is carried by the airflow to the tapered section where it adheres to the sides. The droplet size increases and the droplets are discharged via the drain.
(Mainly compatible with water-soluble cutting fluids)
End Demister
End Demister
Fine mist particles pass through the front, adhere to the end demister, and are discharged via the drain.
(Mainly compatible with water-soluble cutting fluids)
End Filter
End Filter
Fine mist particles pass through the front, adhere to the end filter, and are discharged via the drain.
(Mainly compatible with oil-based cutting fluids)
By changing these combinations, a single machine can be transformed into one of six types in order to meet usage conditions (customers choose interior parts to match cutting conditions and cutting fluid specifications).
3. Includes our own manufactured top runner motor IE3
(excluding 0.4 kW models)
4. Simple, safe maintenance
The filter can be changed while the duct hose is still attached.
5. Corrosion-resistant coating
The impeller is protected by an epoxy coating that prevents rusting.
6. Excellent motor
Our safe designs use IP65-grade protection (dust resistance, sprayed water protection models).
7. Motor with burnout protection terminal
A thermal protector is attached to the motor coil, and this is connected to the operating circuit of the electromagnetic switch in order to prevent burnout.
8. CE compatible
At customer request, we can build CE specification products.
Components cleaners (water-based cleaning agents) / Other (machinery that generates mist)
The series is suitable for applications other than those listed above. Please feel free to let us know your own requirements.

About Piping
1.Duct hose material
Duct hose lifespan is affected by the type of mist being suctioned. We recommend oil-resistant duct hoses.
2. Intake duct piping
① Use easy-to-maintain, vibration damping flexible ducts (optional part).
② When laying out ducts, ensure there is an adequate length without downward sagging.
About Piping
③ For easy mating of ducts, use duct mounting flanges (accessory).
④ When the intake port is placed close to the mist source, large quantities of mist, chips, and dust are suctioning into the machine. This can cause overspill leaks and clogging of the filter and demister. Move the intake port a short distance from the source (about 500 mm), or use a collision plate to prevent overspill leaks and the clogging of the filter or demister.
About Piping
3. Drain tube piping
① Always use a liquid seal on the intake side. (Failure to use a liquid seal will cause air to be drawn in via the end of the drain tube and cause a reverse airflow that will prevent discharge. This forces the airflow to the next filter and thus speeding up clogging.)
② Do not connect the intake-side and discharge-side drain tubes.
③ Be sure to leave the discharge side open to the outside air. (If the drain tube is not open to the outside air, discharge will be impaired and the contents may instead accumulate inside the main unit.)
④ Drain pipes not connecting drain tubes should be sealed with a plug or similar.
About Piping
For Your Safety
● Do not install in dangerous locations
The Mistresa is not built as a pressure-resisting, explosion-proof device. When operated in locations with explosive gases present, motor burnout may ignite the gases, causing an explosion.
● To avoid fires and explosions
Do not attempt to suck up explosive gases, organic solvents, or flames.
● To avoid fires and electric shock
Mistresa wiring installation must be performed by a qualified electrician in accordance with electrical equipment technical standards and internal wiring regulations.
● Do not perform maintenance/inspections while operating
All fans should be stopped before attempting to replace filters or perform inspections.
