TORIT PRODUCTS is the leading designer and
manufacturer of dust collector systems for the
control of industrial air pollution. Its systems are
designed to help reduce occupational hazards,
lengthen machine life, reduce in-plant maintenance
requirements, and improve product quality.
CAUTION
Application of Dust Control Equipment:
• Special care must be exercised in the use of
dust collection equipment when combustible
equipment, such as buffing lint paper, wood
dust, aluminum, and magnesium are present.
These materials may present a fire or
explosion hazard. A prudent user of Torit
equipment should consult and must comply
with all National and Local Fire Codes and/
or other appropriate codes when determining
the location and operation of dust collection
equipment.
• Under no conditions should anyone, including
the machine operator, be allowed to put
burning objects or lit cigarettes into the hood
or ducting of any dust control system.
• Avoid mixing combustible materials with
dust generated from grinding of ferrous
metals due to the potential fire hazard caused
by sparks being pulled into the dust collection
equipment.
• When collection equipment is used to collect
flammable or explosive dusts, the dust
collection equipment should be located
outside the building. Also, an installer of
fire extinguishing equipment, familiar with
this type of fire hazard and local fire codes,
should be consulted for recommendations
and installation of the proper fire
extinguishing equipment. Torit equipment
does NOT contain fire extinguishing
equipment.
• Explosion relief vents are required on some
applications. Consult with an insurance
underwriter or a NFPA Manual to
determine proper vent sizing requirements.
Vents installed on dust collection equipment
within a building must relieve to the outside
of the building to minimize chances of a
secondary explosion. Consult the proper
authority to determine proper method of
venting the dust collection equipment. Torit
equipment does NOT contain explosion
relief vents, except on special order.
• To insure optimum collector performance,
always use Torit-Built®replacement
filters.
NOTE CAUTION
Statements indicate precautions necessary
to avoid potential equipment failure. Statements indicate potential safety hazards.
