PACMAN
The PACMAN first stage inline magnetic separator is designed to effectively remove micron size ferritic particles from amongst others degreasing fluids. The main principle of the functioning of the PACMAN is a tailored combination of magnetic engineering and fluid dynamics:
- Permanent magnetic flux density of 1.28 Tesla (12800 Gauss) and a surface area up to 2.7 m2
- Decelerated longitudinal or transverse fluid flow of > 0.4 m/sec over the magnetic elements
The PACMAN can be delivered with an on-board industrial PLC for stand-alone operation, integrated with the ROTOMAG and/or integrated with the factory control system. Depending on the rate of pollution the PACMAN is automatically drained and rinsed at a configurable frequency by the fully integrated spray cleaning system. The maximum load is 30 kg (dry weight) per m2 magnetic surface. Fe particles are trapped on the outer surface of the stainless steel magnetic elements. In the matrix of the aggregates numerous non-magnetic particles (i.e. sealer and fibers) can be found.
PREMAG
Observing the trends in the automotive industry MHD Magnets is aware of the Nano trend that is taking place, resulting in decreased layer thicknesses at the various stages in the paint line. This makes the separation of even the smallest particles from the pre-treatment stages more important. To anticipate on this we have developed and patented the PREMAG – a flocculation magnetic field located on the inlet side of the filter.This flocculation can significantly improve filtration efficiency for the finest particles.
Formation of aggregates in the flocculation field increases the probability of capturing these larger particles in the main field. A 20% increase in efficiency of particles < 15 mµ is expected.
Besides the PREMAG in new installations, MHD also provide a retrofit PREMAG unit which can be installed in existing installations.

Modular Design
In order to deliver solutions matching the various customer specific processes and requirements, MHD Magnets offers the PACMAN in a modular design. By incorporating options in the design MHD can relief customers from pipe and pump installation activities and the PACMAN can meet the Nano requirement of ever finer separation. Our modular design of the PACMAN filter, enables us to offer our clients the best possible solution for their projects.
Housing module
Type/size of PACMAN based on the flowrates following the factory design specifications.
Flocculation module
(Patented) PREMAG incorporated or not.
Bypass module and flanges
Depending on type of PACMAN, in DN or ANSI.
Drain module: Single or double drain
Using a double drain allows for a two step draining sequence, saving process fluid during draining:
- Drain with elements lowered > Only regular process fluid to be returned to bath/tank;
- Drain with elements raised > Highly polluted process fluid with captured particles to be transferred for further treatment.
In case the MHD ROTOMAG/effluent treatment system is located higher and/or at a long distance, a transfer pump can be mounted in the drain pipeline to transfer the drained fluid to this effluent treatment system.
Control cabinet module
Type of PLC and display in the control cabinet. PACMAN delivered with prewired terminal box or with control cabinet with PLC, display and push buttons. MHD standard PACMAN delivery includes the SIMATIC S7-1200 PLC with a KTP400 display.
