Single-blade 90° paddle
(130 mm, 5.1 inches)
EAL–707–1

Inserted through a 1", 45 mm (1.75 inches)
long process connection.

Default blade, for most applications

Paddle pressure*: 1.4 kPa (0.203 psi)

1" variant, it can be inserted through a 80 mm
(3.15 inches) process connection. The length
of the device must be determined so the
blades can open freely before the threads
meet. Variants with extension pipe or rod are
available.

Paddle cannot be used with sticky materials,
as they may prevent the blades from closing
when removing.

The blades must be closed by pressing the
blade tips together when the unit is installed.

For lighter materials.

Paddle pressure*: 0.8 kPa (0.116 psi)

Inserted through a 1½" process connection.

For coarse or sticky materials. The material stuck
to the blade tends to affect the operation of the
unit less.

Paddle pressure*: 3 kPa (0.435 psi)

Inserted through a 1½", 50 mm (2 inches) long
process connection.
 Shorter insertion length
 Fit for most applications

Paddle pressure*: 1.5 kPa (0.216 psi)

Inserted through a 1", 45 mm (1.75 inches)
long process connection.

For coarse or sticky materials. The material
stuck to the blade tends to affect the operation
of the unit less.
 More robust due to the blade’s small area and
insertion length.
 Paddle pressure*: 10.5 kPa (1.52 psi)

1" variant, it can be inserted through a 80 mm
(3.15 inches) process connection. The length
of the device must be determined so the
blades can open freely before the threads
meet. Variants with extension pipe or rod are
available.

Paddle cannot be used with sticky materials,
as they may prevent the blades from closing
when removing.

The blades must be closed by pressing the
blade tips together when the unit is installed.

For materials with a larger specific weight.

Paddle pressure*: 2.9 kPa (0.42 psi)

Inserted through a 1½" process connection.
 For dense materials.

More robust due to the blade’s small area and
insertion length.

Paddle pressure*: 8.7 kPa (1.26 psi)

Use a mounting plate to insert paddle into the
tank!

Primarily for light materials due to its large
blade.

