flow aids

Flow aids function exactly as their name suggests – they promote the discharge and even flow of dry bulk materials from storage silos, dust collectors, weigh bins, rail cars, and IBC’s.  Breaking up and discharging these materials can be done by mechanical vibration against the storage unit’s wall, or by sound waves.

Flow aids are a simple and safe alternative to sending employees into enclosed areas to loosen stuck product and materials.  If you’re experiencing bridging, rat holing, or compacting of your dry bulk materials, contact IAC’s parts professionals to learn more about how flow aids can improve your operation.  

Silo Fluidizer

Silo Fluidizers: IAC Silo Fluidizers assist with uniform flow and discharge through aeriation and hopper wall vibration.  The aeriation loosens the dry bulk material by providing directional air flow along the hopper wall, while vibration keeps the product flowing.

Sonic Horns: IAC Sonic Horns fluidize unwanted particulate buildup with high intensity, low frequency soundwaves.  IAC has been supplying over 30 different models of Sonic Horns to a variety of industries for over 25 years. 

Specific industries require different frequencies, sizes and materials of construction of horn, which IAC can recommend for you! Sonic Horns can be used in the following industries: Cement, Grain, Wood, Food, Foundry, Steel, PVC Compound, Kaolin Clay, Carbon Black, Power Generation, Spray Dryer Operators and Boiler Operators.

Use IAC Sonic Horns to clean:

  • Baghouses – cleans filter bags and hoppers
  • Food and Dairy Spray Dryers – removes sidewall build-up from dryers, baghouses, and cyclones
  • Electrostatic Precipitators – reduces build-up on collector plates, electrode wires, hoppers, inlet distribution devices
  • Cyclones – eliminates sidewall build-up and discharge plugging
  • Bins & Silos – reduces funneling of powdered material and eliminates discharge plugging
  • Heat Exchangers and Economizers – reduces and eliminates tube build-up
  • Ducts and Conveying Lines – eliminates wall build-up and plugging

IAC Sonic Horn advantages:
Each Sonic Horn is shop tested and tuned for maximum performance. For ease of installation, IAC Sonic Horns can be shipped with shop installed mounting flanges and custom mating connections to fit each specific application. 

Bells and drivers are constructed of either carbon or stainless steel with sanitary fabrication available. 

IAC can save costs to customers by rebuilding, testing, and servicing all makes and models of used Sonic Horns to increase their performance.

IAC can provide high performance, competitively priced spare parts for most all manufacturer`s Sonic Horns.

tube and pipe straights

Specialty Tube and Pipe Straights Available In:

 

  • Induction Hardened: Specialized heat induction hardening raises the material’s Brinell hardness, making it highly abrasion-resistant.

  • Shot Peened: Cold working process used to add strength and resistance to stress, aids in eliminating the buildup of fine materials. Available in Aluminum, Carbon Steel, and Stainless Steel.

  • Spiral Grooved: Internal spiral-grooved straights and pipe and tube bends increase turbulence of materials passing through the system to reduce clogging due to angel hair or stringers.

IAC can accommodate orders from a few pieces to truckload quantities of tube and pipe straights.

Elbows, Bends, and Fittings

IAC carries a wide range of elbows, bends, and wyes to serve your pneumatic conveying needs. From standard light gauge tube bends to extra heavy duty abrasion resistant elbows, we can provide the correct type to fit your application.
Our standard long and short radius bends are available in a very wide range of sizes. Due to the high volume of bends supplied by IAC, many are available from stock and at economical prices.


IAC’s spiral grooved or directionally shot peened elbows and piping help eliminate fines and angel hair in plastics conveying lines. Our abrasion resistant elbows will help save money in loss of material, clean–up costs, loss of production and labor costs due to frequently replacing worn out elbows.


Our complete group of conveying line accessories such as pipe and tubing, compression couplings, hoses, and camlock couplings insure you can get everything you need right here.
