Tank Blowers

Tank Blowers

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.

    All our blowers are 60Hz.

  2. Select Direct or Belt Drive (if needed)

    Some size blowers are only available in direct drive, others can be belt driven as an option.

    Direct Drive

    • More compact
    • Single speed
    • Fewer moving parts
    • No field adjustment

    Belt Drive

    • Field adjustable to vary capacity
    • Flexible to process changes
    • Reduces stress on motor bearings
    • Economical in changing environments
  3. Motor Selection

    Motor Type

    • Totally Enclosed Fan-Cooled (TEFC)
    • Explosion Proof (XP)


    • Housings have no direct openings
    • Internal fan cools motor
    • Insulated
    • UL-approved motor* Insulated


    • Corrosive vapors
    • Dirty, damp or oily service
    • Forward curve blades

    * UL and CSA for Class I, Group D or Class II, Group F and G.

  4. Material Selection of Wheel

    The wheel's chemical resistance takes priority because it is under centrifugal stress.


    • Good chemical resistance
    • Best at room temperature
    • Low cost


    • Very good general chemical resistance
    • Withstands higher temperatures, stresses
    • Potentially explosive fumes or dust

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.
