When it comes topneumatic conveying ofbulk granular materials,our 16 conveying conceptsare state of the art!With over 40 years of building highlyefficient dense phase and dilute phasepneumatic conveying systems, youcan be assured that Dynamic Airtechnology is the latest and the best inthe industry. We have developedmany firsts in the industry, such as ourdense phase Full Line Concept®

system, which significantly reducesmaterial degradation and/or abrasion,lowers maintenance and has tremen-dous energy savings over conven-tional pneumatic conveying systems.

Dynamic Air offers 16 differentpneumatic conveying concepts:

• Four different vacuum conveyingsystems

• Twelve different pressureconveying systems.

Each system has it own unique set ofoperating characteristics for pressure,conveying line velocity, efficiencyand performance. Because each andevery material to be conveyed reacts

differently under a given set ofoperating conditions, it is extremelycritical to match the system operatingcharacteristics to the material to beconveyed in order to achieve the mostdesired conveying performance and toprovide the best value to you, thecustomer.

Our 16 different pneumatic conveyingconcepts have the ability to convey atalmost any conveying velocity desiredto suit a given material to be conveyed.

6

Typical materials conveyed are:alumina, aluminum oxide, baby formula, ball clay, barite, bauxite, bentonite,borax, calcium carbonate, calcium chloride, carbon black, cement, roastedcoffee beans, green coffee beans, cullet, detergent, feldspar, fine coal, flour,fluorspar, fly ash, foundry molding sand, glass batch, glass beads, ground meal,gypsum, iron oxide, kaolin clay, kyanite, lime, litharge, magnesium, milkpowder, peanuts, PVC resin, quartz, roofing granules, salt, silica sand, soda ash,sodium sulfate, steel chips, sulfur, sugar, talc, titanium dioxide and more.

We can convey many materials withconveying velocities as low as 50 feetper minute (0.25 m/sec) using ourHDP 6000 dense phase pneumaticconveying system and, using our LDP2000 dilute phase pneumatic convey-ing system, we can convey at veloci-ties well over 7000 feet per minute(35 m/sec). Plus our conveyingcapacities range from just a fewhundred pounds (100 kg) of materialper hour up to 400 tons per hour andconveying distances exceeding 5000feet (1500 m) in length.

In addition, our pneumatic conveyingsystems become highly efficient whenthey employ our unique patentedDC-5® Air Saver technology and areunmatched for performance andreliability. These systems can handleeven the most difficult of materials,plus they significantly reduce theenergy requirements and conveymaterial at much lower conveyingline velocity with higher conveyingline densities and reduced dynamicloading.

When our DC-5 AirSaver technology isemployed on lowerpressure systemsusing less than15 PSIG (1 barg),in many applica-tions we can lowerthe conveying linevelocity well below

the normal saltation velocity. Dependingon the material being conveyed, we alsocan reduce energy requirements anddrastically improve system performanceand reliability.

The Result:Gentle handling of heavy abrasive andnon-abrasive materials that cannottolerate degradation. For many fragilecrystalline and granular materials thereis no finer material handling process.Dynamic Air’s 16 different pneumaticconveying concepts can offer a moregentle treatment of system componentsas well. Because of lower velocities,system wear and related breakdowns areminimized.

Dynamic Air pneumaticconveying systems are:

• Energy and labor efficient• More reliable, because of our

DC-5 Air Saver technology• Flexible to design in tight plant

environments• Easy to install with minimum

disruption to existing plantproduction

• Clean - because the systemtotally contains the materialconveyed

• Friendly to the environment• Equipped with fewer moving

parts• Lower in initial investment costs• Lower in maintenance

Dynamic Air’s exclusiveDC-5® Air Saver technologyis the key to complete controlof your material throughthe entire conveying line

One of the secrets of a successful andhighly efficient pneumatic conveyingsystem, whether it is a high pressuredense phase system or a low pressuredilute phase system, is trying toachieve an optimum pressure balance.Many systems operate in what we callan unstable and/or unbalancedpressure condition. This means theconveying system can be using eithertoo much compressed air or notenough compressed air, both of whichare undesirable.

When excessive compressed air isused to convey a given material, theconveying velocity will be too highand the result can be material break-down or excessive wear on thesystem. Also, the system will useexcessive energy, and thereforemaintenance becomes higher andreliability is reduced. When notenough compressed air is used, theconvey rate may be too low and it’seven possible that conveying lineplugging can occur.

It is also important to understand thatevery system must constantly fightfriction, and that this friction isusually not evenly distributedthroughout the conveying line.For instance, tubing bends are a majorcause of friction in a pneumaticconveying system and they can easilybe responsible for more than 50% ofthe total resistance of the pneumaticconveying system. The straight tubingin a system, however, has a muchlower level of friction than a tubingbend.

Other friction factors which must beconsidered are components such asconveying line couplings, divertervalves, elevation changes, etc. Also,the shape, density and cohesiveness ofeach material to be conveyed createanother variable which adds to thetotal friction factor, thus impeding theconveying process even further.

8

The DC-5 Air Saver technology isadaptable to almost any type ofDynamic Air pneumatic conveyingsystem regardless of the conveyingpressure or vacuum. The DC-5 AirSaver technology is one of the most

unique products ever developed byDynamic Air and is another first inthe field, making Dynamic Air aninnovator in the field of high perfor-mance pneumatic conveying systems.

Benefits of the DC-5 Air Saver technology• Decreased energy consumption• Improved system reliability• Ability to convey very fragile materials• Ability to convey highly abrasive materials• Ability to convey difficult or cohesive materials• Ability to convey heavy materials• Ability to start and stop the conveying process with

a conveying line full of material• Reduced “dynamic loading” at pipe bends by controlling

the conveying velocity• Reduced dust handling requirements• Reduced material degradation

Therefore, the frictional resistanceseen in the conveying line will varyconsiderably from system to systemand throughout a given system,depending upon the components usedplus the length of the conveying lineand the conveying velocity. Thesevarying and unbalanced frictionalforces in a pneumatic conveyingsystem, if not pressure balancedproperly, can cause unstable andundesirable pressure and velocityconditions, resulting in poor perfor-mance and an unreliable and ineffi-cient conveying system.

In order to create the optimum pres-sure balance in a pneumatic conveyingsystem and to counteract the varyingforces of friction, the compressed airmust be properly and timely distrib-uted for a smooth flow of materialthrough the conveying line.

The pressure balance control must alsobe precise and instantaneous. If thepressure balance control reacts tooslowly or overcompensates, the flowof material through the conveying linewill be disrupted and the performancecompromised.

To effectively counter balance all thefriction factors normally inherent ina pneumatic conveying system,Dynamic Air has developed the DC-5Air Saver technology which accuratelycontrols and pressure balances thepneumatic conveying system.

The DC-5 Air Saver technologyachieves the proper pressure balancebecause it automatically senses theconveying system conditions andreacts instantaneously and accuratelywithout overcompensation. Thusmaterial is conveyed through theconveying line in a smooth controlledmanner and at the desired conveyingvelocity, to optimize the conveyingprocess for higher performance andreliability.
