1.0 SAFETY

IMPORTANT

This manual contains specific precautionary statements relative to worker safety.
Read this manual thoroughly and comply as directed. It is impossible to list all of
the potential hazards of dust control equipment or systems. It is imperative that
the specific use of the equipment be discussed with an AAF representative.
Personnel involved with the equipment or systems, should be instructed to
conduct themselves in a safe manner.

1. Do not mix combustible dusts
such as wood, paper, or buffing
with dust generated from
grinding ferrous metals, due to
the potential fire hazard caused
by sparks in the dust collector.
DO NOT MIX FERROUS
METALS WITH ALUMINUM
DUST.

2. This dust collector should never
be used for the collection of
magnesium dust. Special
precautions and safety items
are required for use with
aluminum dust. It is not
possible to list all hazardous
materials which are not suitable
for collection by this type of dust
collector. It is the responsibility
of the user to consult with their
liability insurance company and
the National Fire Protection
Association (NFPA), Quincy,
MA 02269, telephone number
800-344-3555 (www.nfpa.org)
for procedure to be followed for
the collection of specific dust.

3. Under no conditions, should
anyone put lit cigarettes or any
burning object into the hood or

ducting of any dust control
system.

4. For fire and explosion safety,
The preferred and sometimes
required location for a dust
collector is outdoors. Some dust
collection systems should
include safety devices such as
an explosion relief vent, sprinkler
head, spark detection and
extinguishing system in the main
duct, abort gate, isolation valve
and explosion suppression.

The authority housing jurisdiction
(AHJ), which may be the building
inspector, fire marshal, liability
insurance company or other
party, shall determine which
safety devices may be required.

5. If you smell smoke or have other
reasons to believe there is a fire
in the dust collector or dust
storage container below the dust
collector, DO NOT open the door
or container cover unless you
are a trained fire fighter. The fire
can flash over and discharge a
fireball that can cause severe
burns and/or an explosion.

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.

3.0 INSTALLATION

3.1 Inspection On Arrival

1. Inspect the shipping crate for shipping damage before removing the
dust collector from the crate.

2. Report any damage to the delivery carrier. Whenever possible note on
bill of lading before trucker leaves.

3. Photograph the shipment before and during unpacking to document
damage.

4. Request a written inspection report from the claims inspector to
substantiate claim.

5. Report incomplete shipments to the delivery carrier and your AAF
representative.

6. Remove the upper crating material from the base skid. Remove lag
screws, strapping, etc., that attach the equipment to the skid.

3.2 Site Selection and Unit Location

1. The preferred and sometimes required location for a dust collector is
outdoors if there is a potential for fire or explosion.

2. The Cyclone should be located with consideration for maintenance,
inspection, shortest possible run for duct and electrical work and
access for emptying dust receptacle (drum, bin or hopper).

3. When hazardous conditions or materials are present, consult with local
authorities for the proper location of the collector.

4. If unit is installed indoors and has an explosion vent, then provision
must be made to duct the explosion vent to outside of building, away
from normally occupied areas.

5. Prepare the concrete pad in the selected location. Anchor bolts should
be a minimum of 5/8” diameter, with 5” embedment. The pad design
and anchor bolt system should be calculated by a structural engineer.
