B L O W E R SBlowers for Lab and Industrial UseReliable, All-Plastic Corrosion-Resistant UnitsLAB-STYLE BLOWERDIRECT DRIVE UNITSaint-Gobain Performance Plastics’Norton ® Blowers are excellent choicesfor aggressive applications where metalblowers quickly corrode. Metal blowersrely on protective coatings, which developpin holes and pores. Corrosive vaporsseep through and attack the metal,causing failure. Plastic blowers lastmuch longer because the material isinherently resistant to corrosion.The smaller laboratory units have roundinlets and outlets. They are designed foruse in lab hoods and cabinets. They areavailable in direct drive with 2 motoroptions and 2 wheel options.The industrial units have round inletsand square outlets and offer muchgreater capacity.They are proven performers in toughindustrial applications, such as metalfinishing, chemical manufacturing,wastewater treatment, and chemicalstorage cabinets. In addition to theoptions for drives, motors, and wheels,a full line of transitions and flexibleconnectors is available for connectionto ductwork.Norton blowers are ordered by selectingthe right capacity, type of drive, motorand combination of plastic materialsfor your application. The “Four Steps toBlower Selection” on the followingpages will guide you.Blower Features• Corrosion resistant• Outlasts metal• Quiet operation• Choice of motors/materials• Reinforced housing• For indoor and outdoor † use• Plastic transitions for easy attachmentto standard ducting• Full line of replacement partsIf installing your own motor, note thatNorton blowers must not exceed thestated RPM of each blower (pages 32-34).Industrial blowers feature round inletsand rectangular outlets. (For plastictransitions, see page 36)NOTE: Blowers are supplied fully assembledin counterclockwise upblast position. Othercounterclockwise positions are available onrequest.*†Protect motors and drives against weatherwhen blowers are roof-mounted.All outdoor vertical blower discharge ductsmust have weather hoods.*Except Cat. No. 71300 Series Lab Blower—no bottom horizontal or down-blast positions.BELT DRIVE UNIT30
B L O W E R SBlower SelectionFour Steps to Blower Selection1. Determine CFM and Static PressureCFM 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 incomingair flow from ducts, fittings, elbows, dampers, and other factors.You can determine your existing unit’s capacity by checking the size and performancespecs. For new installations, the CFM and Static Pressure should be determined by amechanical engineer, HVAC contractor, ductwork manufacturer or other professional.All our blowers are 60Hz.For performance curves, please contact Customer Support.2. Select Direct or Belt Drive (if needed)Some size blowers are only available in direct drive. Others can be belt driven as anoption. Consult page 35 for availability.Direct DriveMore compactSingle speedFewer moving partsNo field adjustmentBelt DriveField adjustable to vary capacityFlexible to process changesReduces stress on motor bearingsEconomical in changing environments3. Motor SelectionMotor Type Features ApplicationsTotally Enclosed Fan-Cooled (TEFC)Explosion Proof (XP)Housings have no direct openingsInternal fan cools motorInsulatedUL-approved motor*InsulatedCorrosive vaporsDirty, damp or oily serviceForward curve blades* UL and CSA for Class I, Group D or Class II, Group F and G.4. Material Selection of WheelThe wheel’s chemical resistance takes priority because it is under centrifugal stress.PVCGood chemical resistanceBest at room temperatureLow costPolypropyleneVery good general chemical resistanceWithstands higher temperatures, stressesPotentially explosive fumes or dustGENERAL NOTES: Lab Blowers (sizes codes -0050 to -0150) have round inlets and outlets.Industrial blowers have round inlets and rectangular outlets (see dimension charts).All blowers used outdoors must be protected against weather.Blowers are supplied in counter-clockwise up-blast position. Other positions may be requested.31
