AcoustiClean — Model ACL 9475 Sonic Horn

AcoustiClean® Sonic Horns are designed to produce high-energy, low-frequency sound vibrations to disperse and prevent costly buildup of material in hoppers, bins, silos, boilers, ESPs, SCRs, fans and more.

Sound waves are produced by applying compressed air to the sound generator, vibrating a high-strength titanium diaphragm. A typical pulse length is 10 seconds with each pulse using approximately 10 cfm of compressed air.

Model ACL 9475 is the largest AcoustiClean sonic horn. Common applications include baghouses, SCRs and ESPs, as well as placement on top of bins or hoppers to break up bridging or ratholing. The effective cleaning distance is up to 60 feet in front of the horn and 20 feet in diameter.

AcoustiClean® Sonic Horn Applications
Boilers	Cleans heat transfer surfaces to increase heat transfer efficiency and eliminate the need for soot blowers.
Baghouses	Helps reduce pressure drop across surfaces, extending bag life.
Industrial Fans	Eliminates material build-up on blades.
Electrostatic Precipitators , ESP	Eliminates rapping system and wear to plates and wires.
Silos, Bins, and Hoppers	Eliminates ratholing, bridging and prevents particulate buildup on vertical walls.
Selective Catalytic Reduction , SCR	Cleans catalysts.

Typical Sonic Horn System Components

Sonic Horn — Specify model number

Solenoid Valve — Controls the flow of air to the horn.

1″ Locking Ball Valve — Ideal for isolating the horn when system maintenance is required.

Stainless Steel Flex Hose — Connects the solenoid valve and hard piping from your compressor.

Titanium Diaphragm — The only moving part in an AcoustiClean® sonic horn is the titanium diaphragm, which should be replaced annually.

1″ High-Flow Particulate Filter  — Enhances life of system components by removal of in-line contaminants.

1″ High-Flow Regulator — Necessary for regulating compressed air supply to within 70-90 psi for proper horn operation.

Timers — Two options are available to control the interval and length of time the AcoustiClean® horn will sound.

1. Timer/sequence controller designed to control multiple sonic horns.
2. Timer plugs into the DIN contacts on the valve to control one horn.
