Whether your concern is pollution abate-ment, re-entrainment, or odor control, Tri- stack systemsoffer an effective solution for you.

2 Operating at thousandsof facilities as direct replacements for tall, unsightly conventional centrifugal Exhaust fans, Tri- stack systemsoffer several benefits you won t find anywhere else. Modular construction allows for easy installation and lowsystem pressures to provide a fast payback when com-pared to traditional centrifugal stack Exhaust designs. Thelow profile design, low noise levels, variable air volume control, and vibration free operation all result from the superior design and construction of the Tri- stack Systems are also virtually maintenance-free, offering significant cost savings for labor while eliminatingthe need for rooftop penthouses and expensive vibrationcontrol measures.

3 Direct drive motors exhibit up to L-10150,000 hours eliminating the need to replace belts, pulleys, or other limited life Systems are ideal for use in hospitals, biomedicalfacilities, and research laboratories at universities as wellas private pharmaceutical, chemical, and petrochemicalorganizations. Specialty applications from diesel genera-tor Exhaust to emergency ammonia fume extraction arealso common and can be custom designed for your Systems are the industry leader wherever issuesof Exhaust pollution, odor control, re-entrainment, aesthet-ics, or energy savings are a Systems roof Exhaust fans: configurations for any project size or applicationTri- stack Systems can be designed for retrofit and new construction.

4 They can be configured to meet your designrequirements, as well as optimize efficiency to ensure youhave the best possible design. Strobic Air s experiencedstaff will be pleased to work with you to determine the bestpossible Tri- stack configuration for your Air s Tri- stack : Three stacks in one fanThere exists a common misconception that TRI in Tri- stack equates tothree fans. However, intruth, TRI refers to theunique ability of each individual fan in the Tri- stack series to incorpo-rate three stacks (orstreams) of air into a single plume, which is composed of the following: The first stack comes from the building source second stack is induced through the windband. This stack allows the nozzle plume to develop fully before exiting the top of the windband and helps shield it from cross-winds.

5 The third stack is entrained through the teardrop shaped motor cut-outs of the unique nozzle design. The nozzle design allows the motor to remain outside of the hazardous Exhaust stream, therefore allowing for easier maintenance and long life cycle. This stack adds air volume to the center of the stack as well as allows ambient air for cooling of the Air s Tri- stack fan is the industry s mostefficient, best cost of ownership, and reliable fan. 1223123 The Power of Innovation Consider these outstanding advantages of Tri- stack fans and systemsPrevent re-entrainmentTri- stack Systems send a vertical plume of diluted exhaustgas up to 150' high, providing atmospheric disbursementand preventing Exhaust from re-entering the facility throughfresh air supply ventilation Systems , doors, and odorEntrainment of outside air and vertical trajectory of exhaustair by Tri- stack fans effectively dilutes and dispersesodors, preventing them from entering or lingering near thefacility and neighboring noise at the property lineTri- stack Systems are inherently quiet.

6 Direct drive motorseliminate the noise generated by fans with belts and pulleys; high efficiency operation permits use of smallerhorsepower motors; more efficient blade design con-tributes to quieter operation. Our mixed flow, direct driveimpellers allow us to balance to the industry best of peak to peak which contribute to lowest sound levelsfor any fan compared to all other fan manufactures. Whennoise is especially critical, Strobic Air offers a selection of noise attenuation accessories and options described in more detail on the following with architectural and aesthetic ordinancesLow profile Tri- stack Systems are often not visible from theproperty line.

7 Problems associated with tall, unsightlystacks such as the perception of exhausting polluted airinto the neighborhood are eliminated with Tri- stack Systems . Since many communities have strict ordinancesgoverning height of building Exhaust stacks, Tri- stack Systems are ideal for code compliance in virtually all engineers are also able to work with you to createcustom designs to comply with any requirements that arenot already cost of ownershipThe direct drive configuration of the Tri- stack system combined with mixed flow impeller design allows for superior energy efficiency compared to a belt driven system . Based on current energy costs, a typical Tri- stack system can provide a full return on investment (ROI) in aslittle as two years.

8 Strobic Air offers accessory energy recovery and Smart system controls that can further reduce energy costs. In addition, our 7-year warrantymakes Strobic Air Tri- stack Systems the industry leader inoverall cost of flow impeller technology: the key to superior performanceTri- stack Systems provide significant perform-ance, reliability, and cost advantages over conventional centrifugal Exhaust fansStrobic Air has refined mixed flow technology fans for almost three decades, and has pioneered many aerody-namic concepts with the technology. Mixed flow fans provide optimum performance in virtually all configurationsof low pressure/high flow and high pressure/low offer substantial advantages over centrifugal-type fanssuch as higher efficiency performance for lower horse-power requirements for comparable pressures and constant acceleration ratio of mixed flow fan bladespermits both the leading and trailing edges to performequal work, maximizing efficiency and providing a stableperformance curve without stall or un-stall Tri- stack Systems require so little maintenance,building maintenance workers are freed up to spend theirtime on productive work.

9 In addition, the need for rooftoppenthouses to protect maintenance workers is also elimi-nated, reducing costs and weight on the roof a direct operating cost basis, use of Tri- stack mixedflow fan technology reduces energy consumption.
