MistBuster Oil Selector Switch

July 20th, 2017 | Posted in Air Cleaners

Our patented water/oil selector switch is one feature that makes our mist collector units stand out from the other electrostatic mist collection units on the market. Water soluble coolant has an increased conductivity when compared to oil-based coolant. The patented technology of the water/oil selector switch provides the unique ability to adjust the electrical properties of the MistBuster® to match the type of coolant used.

Switching the MistBuster® between water and oil mode is simple. On the MistBuster® 500 and MistBuster® 850 models, simply push the knob(s) on the back of the unit in for water mode or pull the knob(s) out for oil mode. On the MistBuster® 2000, rotary selector switches on the front of the unit allow you to switch between water and oil mode by turning the knobs. The water/oil selector inside the MistBuster® works in water mode by opening the connection from the power supply to the collector side of the cell. In oil mode, the connection between the power supply and collector side of the cell is closed.

You might be wondering how the cell can function when you just disconnected the power to the collector side of the cell. When the MistBuster® is in water mode, the collector side of the cell gets an induced charge from the high voltage of the ionizer section and the collector side of the cell builds up a charge of about half of what it would have when in oil mode. This lower, induced voltage allows more build-up of water-soluble coolant on the cell plates without shorting out the power supply or the cell itself. Without the water selector switch, the high voltage on the collector plates combined with a buildup of water-soluble coolant creates a situation where the cell is likely to short out effectively disabling the electrostatic filtration.
