Component Identification
The Twistork Helix Agitator is intended to mix and
maintain paints and similar fluids in closed-head,
55-gallon (200-liter) drums with 2 in. npt bung
connections. The Twistork Helix Agitator provides
suction porting through its siphon tube, which allows you
to siphon fluid to a pump while mixing it.
Standard Agitator, Model 236629
The standard agitator operates in a center-lift fluid
rotation mode, which is preferred in most applications
because it minimizes fluid aeration. The helix rotates
counterclockwise and mixes fluid by lifting it up from the
bottom of the drum. See F
Standard agitator Model 236629 cannot reverse its
helix rotation.

Rotation
Oil-less Reversible Agitator,
Model 236760
The oil-less reversible agitator operates the same as the
standard agitator, but it uses a non-lubricated air supply,
and the helix rotation can be reversed.
NOTE: Although the air motor can operate without oil,
motor life is increased when lubrication is provided.
To reverse the helix rotation on reversible agitator Model
236760, remove the air motor muffler (16a) and needle
valve (18), and switch the ports they are installed into.
See F
When the helix rotation is reversed, the agitator
operates in a pull-down fluid rotation mode, which can
be better for agitating fluids that are difficult to put into
suspension. The helix rotates clockwise and mixes fluid
by pulling it down from the surface. See F
With clockwise (pull-down fluid rotation), care must be
used at high speeds to prevent cavitation, which could
be caused by air being drawn down to the siphon inlet.
