Dwyer Model FD-1/MFD-1 Fluidizer Disk combines aeration and vibration to solve the most difficult bulk solid flow applications.

The special design creates a vibration as the air flows between the pads boot and bin wall. This provides a very effective flow aid for all types of dry products.

The FD does not require a specific air pressure for operation. Your pneumatic system pressure can range from 29 to 87 psi.

The unique design of the Fluidizer Disk allows the pad to be mounted on virtually any kind of surface, but for best results, try mounting on a clean and smooth surface.

Specifications – Installation and Operating Instructions
The Model FD Fluidizer Disk combines aeration and vibration to solve the
most difficult bulk solid flow applications. The special design creates a vibration
as the air flows between the pads boot and bin wall. This provides a very
effective flow aid for all types of dry products. Plus the FD does not require
a specific air pressure for operation. Your pneumatic system pressure can
range from 29 to 87 psi.
HOW IT WORKS
Air is introduced in the silo or bin through the fluidizer disk. As the air discharges
in the material it provides aeration effect to fluidize the material. The positive
air pressure keeps the material from getting under the boot. The air flowing
under the boot causes it to vibrate. The vibration of the boot helps move
material that has a tendency to hang up or bridge. When the air is removed
from the boot, the pressure of the material and the design of the boot forces
the boot against the side of the bin. This prevents material from getting under
the boot and into the air supply line.

INSTALLATION
To install the Fluidizer Disk, drill a 7/8˝ hole in the hopper, bin, silo, etc., wall
where material flow is a problem. From the inside, place the stainless steel
shaft and silicon disk assembly through the walls, from the outside, slip on
the sealing washer, flat washer and hexagonal nuts. Tighten down until snug.
The unique design of the Fluidizer Disk allows the pad to be mounted on
virtually any kind of surface, but for best results, try mounting on a clean and
smooth surface.
TYPICAL MOUNTING CONFIGURATION
MAINTENANCE
Upon final installation of the Model FD Fluidizer Disk, no routine maintenance
is required. A periodic check of the system is recommended. The Model FD
is not field serviceable and should be returned if repair is needed (field repair
should not be attempted and may void warranty). Be sure to include a brief
description of the problem plus any relevant application notes. Contact
customer service to receive a return good authorization number before
shipping.
