AAF International AAF-CY44-50 - Manual (Page 4)

2.0 INTRODUCTION
2.1 General
Congratulations on your selection of a AAF Cyclone dust collector. As the
owner/operator of this unit you have an important responsibility to see that it is
operated and maintained in a safe manner. The unit will require very little
attention to keep it in good operating condition. This manual has been prepared
to guide you in the installation, operation and maintenance of this dust collector.
Reference may be made to various configurations and options which may or may
not be part of your particular system.
2.2 Description
Cyclone dust collectors are mechanical separators that use centrifugal forces to
remove particulate from the airstream. The Cyclone provides high-efficiency
separation due to its high inlet velocity, long tapered cone, and internal helix.
2.3 Intended Use
Cyclones are most commonly used in applications generating high dust loads,
such as woodworking and machining, where coarse or large dust particles are
produced. The Cyclone can be used alone or with filter bags, depending on
whether the discharge air is exhausted to the atmosphere or returned to the
plant.
When air streams have high dust concentration of coarse and fine particles from
a production operation, the Cyclone is used as a pre-cleaner to a jet pulse bag or
cartridge dust collector.
2.4 Operational Description
The Cyclone cleans the air by centrifugally separating the dust from the air
stream. Dust laden air enters tangentially and is forced into a downward spiral.
The dust particles, which are heavier than air, concentrate in a thin layer next to
the Cyclone wall. When the helix of dust and air reaches the bottom, the air flow
reverses and escapes up the center of the Cyclone. The particles fall into the
dust container. Those particles of dust which are too small to be captured by the
Cyclone are caught by the optional after filter bags.
