Cyclonic Filtration

Since 1974, Encyclon has been designing and manufacturing cyclonic filtration systems. Our knowledge and applications experience have made us a leader in the industry.

Encyclon Cyclonic Filtration Systems filter, circulate and store coolants for metalworking and other water-base or synthetic liquid operations. They operate on the simplest, most efficient means of separating foreign particles from liquids: centrifugal force generated in a cyclonic chamber. They employ no filter media or diatomaceous earth. Because of its double cleansing action, the Encyclon cyclonic chamber removes 98% of all particles to 3 or 5 microns without impairing the original.

Here’s How It Works

Dirty coolant enters the cyclone at the inlet orifice (1) of the cyclonic chamber (3).

The shape and tangential location of the orifice develop a downward, spiraling flow of the coolant. This is called the primary whirl (4), which follows the chamber walls because of centrifugal force of up to 7500 times that of gravity.

This same force spins out the solid particles to 5 microns, or .00019” diameter from the coolant. The solid particles strike the wall and slide down to the discharge orifice (7).

A throttling effect in the lower (ceramic) cyclonic chamber (6) reverses the descent of the coolant but not the rotation. This forms the secondary whirl (5), a rising, spiraling flow of cleaned coolant that passes up through the primary whirl to the whirl searcher (2).

The diameter of the whirl searcher is smaller than the secondary whirl, and the whirl searcher accepts only the center of the upward, secondary whirl flow. The outside portion of the secondary whirl (containing impurities missed by the primary whirl) is diverted back to the primary whirl for further cleansing. Coolant that passes through the whirl searcher is then piped out to the clean coolant storage tank or to the machine tool.

Two Styles of Cyclones

The two styles of cyclones offered by Encyclon give you a choice of either 3 or 5 micron filtration, both with 98% efficiency. The number of cyclones fitted on a system will vary depending on the flow rate you require.

Type Number 28

Offers 3 micron filtration and a 5 gallon per minute flow rate per cyclone.

Type Number 65

Offers 5 micron filtration and a 20 gallon per minute flow rate per cyclone.
