Acoustic Cleaning and 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 Sonic Horns to a variety of industries for over 25 years. 

Specific industries require different frequencies, sizes and materials of construction of horn. You can browse our Sonic Horn Application Manual for more information, or contact our parts sales department for help.

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 provide the correct type to fit your application – from standard light gauge tube bends, to extra heavy duty abrasion resistant elbows. 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.
