Component parts: Filter medium
dosing units (FD)
FAUDI filter medium dosing units are used in all application areas of bulk material dosing. Precoat filters, for example, require the dosing of filter aids such as cellulose, diatomaceous earth or perlite for the precoat process. Other media suitable for metering are granules and powders, such as corn granules (MK-100) or bleaching earth (Tonsil Standard 312 FF). FAUDI dosing units are used in all FAUDI precoat filter systems. The dosing units are available in four different sizes: FD-125, FD-400, FD-1000 and FD-1500 Big Bag.
Furthermore, we offer our
dosing units in the following
versions and options:
- Atex version
- Pneumatic beater
- Bag tightening by spring strut
- Screw conveyors DN100 or DN150
- Vacuum conveyor
- Multiple discharge
- Electric weighing systems
- Stainless steel design
- Big Bag loading with electric chain hoist or with forklift loading unit
- Own control system with operating panel
Whether for small machine tools or large central systems – special solutions can be configured according to your individual requirements.

Design layout
Filter medium
dosing units
(FD-1500 BiG BAG)
The filter medium dosing unit consists of the following components:
1. Big bag
2. Loading unit with chain hoist
3. Big bag support
4. Filter aid tank
5. Cross-feeding screw conveyor
6. Steep crew conveyor
7. Outlet

How does a
Filter medium
dosing unit work?
FD-1500 Big Bag
The connection hose of the big bag is pulled over the nozzle of the bunker and fixed tightly with the bag buckle so that the big bag can be opened. The filter aid falls into the hopper. The agitator blade in the hopper loosens the filter aid. The filter aid is then conveyed into the precoat tank of the filter system by the plug screw and the steep screw.
