Installation, Operating and Maintenance Instructions

®
The Type N RotoClone is a complete dust control unit. Designed
to perform its various functions automatically, the RotoClone
requires very little maintenance. Like any other mechanical
equipment, however, it should have regular attention and be
operated according to instructions to insure long life and
trouble-free service.
Design 2 and 4 have the exhauster on the clean air side of the
Type N RotoClone. In the Design 3 and 5, the exhauster is on the
dirty air side and discharges into the Type N RotoClone.
It is recommended that the back page of this manual be filled
in with specific design details for future reference. These
include: design number, sludge ejector control device, operating
line, type of water level control and wiring diagram that applies
to this Type N RotoClone.
Operating Principle
The Type N RotoClone cleans the air by the combined action of
centrifugal force and a thorough intermixing of water and dust-laden
air. The dust is separated from the air by means of a water curtain,
created by the flow of air through a partially submerged stationary
impeller (see Figure 1). Air flowing through the impeller at a high
velocity conveys water with it in a very turbulent sheet. Additional
water is introduced at the narrowest portion of the impeller opening
through a specially designed slot at the bottom. Since there is a
certain pressure drop through the impeller, the water flows upward
through the slot in an attempt to reach the water level on the clean air
side. The water flow upward through the slot creates increased
interaction between the dust and water, thus, increased collection
efficiency. Since the water flows upward in an attempt to reach the
level on the clean air side of the impeller, the impeller opening can be
decreased (resulting in higher pressure drop and collection efficiency)
by raising the water level in the unit. This is accomplished by means
of an exclusive and patented variable water level control box. The
centrifugal force exerted by rapid changes in direction of flow causes
the dust particles to penetrate the water film and become permanently
trapped. (Figure 1).
