Application brief
Blower Solutions for Infrastructure and Civil Engineering
Civil engineering and infrastructure work covers an unusually wide range of environments for a single equipment category to serve. A stormwater dam needs its gate agitated so it doesn't freeze shut in winter. A brownfield site needs contaminated soil vented safely and continuously, for years, without failure. A road crew grinding concrete slabs, bridge decks, and airport runways needs a high flow vacuum system light enough to keep the equipment maneuverable. A cement plant needs clinker cleared from its conveyor belts without wearing through scrapers and doctor blades. None of these have much in common on the surface, but they share the same underlying requirement: a blower that keeps running reliably in a demanding, often unattended environment.
Sonic Air Systems' centrifugal and hydraulic-driven blower platforms have found their way into exactly these situations, protecting municipal infrastructure, supporting environmental remediation, and powering the equipment crews rely on to build and maintain roads, bridges, and other civil works.

Key Takeaways
Key takeaway
Penhall has deployed hundreds of Sonic hydraulic-driven vacuum blowers since 1993, replacing 700 lb positive displacement blowers with a 75 lb, 20 HP hydraulic unit, a reduction of over 600 lbs, while eliminating the need for extra in-line filtration on concrete grinding equipment.
Key takeaway
Sonic blower systems support methane and other hydrocarbon soil vapor mitigation at sites including Universal Studios Hollywood, where a 20 HP system runs 24/7 inside a low decibel enclosure.
Key takeaway
Sonic's non-contact air knife has replaced belt scrapers and doctor blades at many of North America's largest cement producers, blowing clinker directly into the plant's dust collector.
Key takeaway
Sonic's hydraulic-driven marine duty blowers also support rapid oil containment boom deployment for emergency oil spill response.

System requirements
Stormwater and Water Management Infrastructure
The New York City Department of Environmental Protection needed to keep a stormwater overflow dam's sluice gate from freezing and clogging with debris and sediment, since stagnant water around the gate froze over in winter and interfered with proper flow control. Sonic supplied a Centrifugal Blower System housed in a weather-proof acoustic enclosure, delivering high volumes of low-pressure air through an underwater pipe network to keep the water around the gate agitated, the same approach Sonic uses in retention pond aeration. The system has kept the sluice gate clear and functional through freezing temperatures, protecting critical stormwater infrastructure and uninterrupted drainage all winter.
Engineering detail
Concrete Finishing and Road Surface Equipment
Concrete grinding and grooving equipment for freeways, bridge decks, runways, and other driving surfaces has to pick up concrete debris and water slurry without adding excess weight or bulk to the machine. Penhall, a concrete finishing, cutting, and grinding provider, had been running 700 lb positive displacement vacuum blowers rated at 12" Hg and wanted a lighter, lower-maintenance alternative. Sonic's hydraulic-driven vacuum blower, running at 6 to 7" Hg with higher inlet CFM, matched the pickup performance in a package that weighs just 75 lbs and occupies less than 2 square feet of platform space, a reduction of over 600 lbs per unit. Paired with Penhall's cyclone separator for bulk water and heavy particulate, the Sonic blower handles the remaining fines and water vapor without additional filtration or a separate silencer, and runs quieter than the grinder itself.
System requirements
Mining and Cement Production
Conveyors carrying wet or sticky material like cement clinker have traditionally relied on contact scrapers and doctor blades. Those blades wear out, can damage the belt, and still let dust escape, which matters more every year as emissions rules tighten. Sonic's non-contact XE air knife blows residual clinker and powder off the belt and straight into the plant's dust collector inlet, containing particulate at the source. The approach is now standard at many of North America's largest cement producers, with better safety, near-zero product loss, and less maintenance than contact scrapers.
Engineering detail
Soil Vapor Extraction and Brownfield Remediation
Methane gas in soil, whether from natural sources, landfills, or leaking storage tanks, has to be vented and monitored continuously to meet EPA standards or fire safety regulations. Sonic has worked with environmental engineering firms on methane and other hydrocarbon soil vapor mitigation systems, including passive soil gas extraction and venting, and pressurized air barrier systems. With land reclamation projects on the rise, Sonic blowers are specified with low decibel enclosures so they can run 24/7 in residential areas without objectionable noise.
At Universal Studios Hollywood, a 20 HP Sonic Air Blower System extracts methane gas as part of the site's soil vapor mitigation system. At the Vista Del Rio residential community in Commerce, CA, a dual 10 HP system with integrated monitoring controls maintains a pressurized air barrier against methane intrusion. At Pick-A-Part Salvage Park in Monrovia, CA, a dual 7.5 HP weather-proof system does the same job, equipped with panel monitors, motor soft starters, pressure switches, and a data recorder.

Preventing Winter Freeze-Up on a NYC Stormwater Sluice Gate
The New York City Department of Environmental Protection needed to prevent a stormwater overflow dam's sluice gate from freezing and clogging with debris and sediment, since stagnant water in the dam had to stay agitated to maintain proper flow. Sonic supplied a Centrifugal Blower System in a weather-proof acoustic enclosure, delivering high volumes of low-pressure air through an underwater pipe network to keep the water moving along the gate. The installation prevented the sluice gate from freezing and ensured uninterrupted stormwater drainage through the winter, protecting critical infrastructure from weather-related disruption. Full details are in Sonic's published case study, Sonic's Centrifugal Blower System Keeps NYC's Sluice Gate Clear and Functional.

Over 600 lbs Lighter: Hydraulic-Driven Vacuum Blowers for Penhall
Penhall, which has provided concrete finishing, cutting, and grinding services since 1957, wanted an alternative to the 700 lb positive displacement/rotary lobe vacuum blowers on its concrete grinding equipment, which limited maneuverability and required extra filtration and a separate silencer. Sonic's hydraulic-driven vacuum blower, running at 6 to 7" Hg with higher inlet CFM, matched the pickup performance for concrete debris and water slurry in a 20 HP unit weighing only 75 lbs and taking up less than 2 square feet of platform space, cutting weight by over 600 lbs per unit while eliminating the need for additional in-line filtration. Penhall has deployed hundreds of Sonic hydraulic-driven vacuum blowers since 1993, reducing maintenance costs, improving maneuverability, and operating at sound levels lower than the grinders without any added silencing devices. Full details are in Sonic's published case study, Improved Safety in the Concrete Finishing Industry with Sonic Hydraulic-Driven Vacuum Blowers.
