Reliable, All-Plastic Corrosion-Resistant Units Saint-Gobain Performance Plastics'
Norton® Blowers are excellent choices for aggressive
applications where metal blowers quickly corrode. Metal
blowers rely on protective coatings, which develop pin holes
and pores. Corrosive vapors seep through and attack the
metal, causing failure. Plastic blowers last much longer
because the material is inherently resistant to corrosion.
The smaller laboratory units have
round inlets and outlets. They are designed for use in lab
hoods and cabinets. They are available in direct drive with
2 motor options and 2 wheel options. The industrial
units have round inlets and square outlets and offer much
greater capacity.
They are proven performers in tough
industrial applications, such as metal finishing, chemical
manufacturing, wastewater treatment, and chemical storage
cabinets. In addition to the options for drives, motors, and
wheels, a full line of transitions and flexible connectors
is available for connection to ductwork.
Norton blowers are ordered by selecting the right capacity,
type of drive, motor and combination of plastic materials
for your application.

If installing your own
motor, note that Norton blowers must not exceed the stated
RPM of each blower.
Industrial blowers feature round inlets and rectangular
outlets.
NOTE: Blowers are supplied fully assembled in
counterclockwise upblast position. Other counterclockwise
positions are available on request.*
+Protect motors and drives against weather when blowers are
roof-mounted.
All outdoor vertical blower discharge ducts must have
weather hoods.
*Except Cat. No. 71300 Series Lab Blower-no bottom
horizontal or down-blast positions.
Four Steps
to Blower Selection
1. Determine CFM
and Static Pressure
CFM is Cubic
Feet per Minute and represents the volume of the
area to be ventilated.
Static Pressure is measured in inches of water.
It is the total resistance to incoming air flow
from ducts, fittings, elbows, dampers, and other
factors.
You can determine your existing unit's capacity
by checking the size and performance specs. For
new installations, the CFM and Static Pressure
should be determined by a mechanical engineer,
HVAC contractor, ductwork manufacturer or other
professional.
Some size
blowers are only available in direct drive,
others can be belt driven as an option.

GENERAL NOTES: Lab
Blowers (sizes codes -0050 to -0150) have round inlets and
outlets. Industrial blowers have round inlets and
rectangular outlets. All blowers used outdoors must be
protected against weather. Blowers are supplied in
counter-clockwise up-blast position. Other positions may be
requested.
