Comparison With filters for particulate removal

Electrostatic cleaning should not be confused with mechanical filters.
Mechanical filters work as "barriers" with a designated pore size. Fluid is pressurised through a mechanical filter.
In Electrostatic Cleaning, contamination removal is by "Electrostatic" process.

	Mechanical Filters	ELC
	Cannot effectively remove contaminants below 10 microns	Removal efficiency exceeds 0.1 microns
	Low collection efficiency: A filter holds 1/10th its weight in contaminants	A collector holds twice its weight in contaminants
	High replacement cost	Low replacement cost
	High energy consumption to pump oil through filters	Low energy consumption as this is a kidney-loop system
	Cannot retard oxidation / sludge formation	Retards oxidation / sludge formation
	Cannot prevent wear of pumps	Prevents wear of all moving parts
	Hydraulic parts like pumps, valves, oil seals require replacement inspite of using filters	If ELC is dedicated, & oil temperature is controlled, life of components is indefinite
	Machine efficiency reduces & cycle time increases as filters get choked	Ensures stable cycle time
	Cannot remove sludge	Only system which efficiently removes sludge
	Fine mesh, synthetic filters cause high volt electrostatic spark discharge cracking oil molecules. This also depletes oil additives	Totally safe for oil. No harm to additives
