Sonic’s patented heater-less hot air knife systems deliver air at 125°F to 275°F (52°C to 135°C) from the blower’s natural heat of compression, with no electric heater or flame. They dry water-based coatings, paints and inks and use up to 75% less energy than electric, gas or steam heaters.

Patented hot air blower technology for industrial applications requires no electric heater or live flame element.
Sonic Air Systems understands that every industry and application has unique needs. That's why our industrial hot air blowers are engineered to meet each customer's specific objectives, delivering precise heated (variable temperature/fixed temperature) technology for forced convective drying. Eco-friendly and energy-efficient Sonic air flow ranging from 125°F to 275°F (52°C to 135°C) with our innovative VT (variable temperature's) heater-less hot air blower systems eliminate the need for any inline heaters.
A hot air knife system is an industrial device that uses a high-velocity stream of heated air to perform tasks like drying, curing, heating, or removing moisture from surfaces. It consists of a blower and air knives. In Sonic’s patented heater-less design, the blower’s own heat of compression warms the air, so no separate heating element is needed. Unlike traditional methods that rely on inefficient heat sources, a hot air knife system delivers targeted, uniform airflow, making it ideal for applications that require consistent heating across a production line. Industries such as automotive, food processing, textiles, and packaging commonly use heated air blowers to accelerate drying times, enhance product quality, and reduce energy consumption.

Determining the best valve for your system depends on balancing air volume, pressure, and material characteristics. When these factors align, you achieve smoother performance, higher efficiency, and long-term reliability. The ideal configuration not only maintains consistent airflow and minimizes pressure loss but also enhances energy efficiency across continuous production cycles.
When specifying an industrial air diverter valve, consider the following engineering factors to ensure long-term reliability:
Bolt-together stainless steel air knife tunnels for drying bottles and cans before inspection, coding, labeling or packaging, at 100 to 1,500 products per minute. Standard modules are 24, 48, 72 and 96 in long, and sealed drip pans contain water and prevent rewetting.

Ionized air rinser and air wash systems that replace water rinsing and compressed air blow-off for cans, bottles and other products. Ionizing bars neutralize static so dust and particles let go, and blower power uses 75% less electricity than compressed air rinsing.

Air knives and nozzles that cycle up and down as parts pass on overhead monorail conveyors, so one Reciprocating Air Knife (RAK) system does the work of several stationary knives. Used for drying before coating and for shot blast blow-off on automotive, farm machinery and other large parts.

The Sonic Cool Air Knife System blows ambient or refrigerated air through high-velocity air knives to cool parts after welding, heat treating or thermoforming. It runs on a blower instead of compressed air and can replace or reduce water spray cooling and chilled cooling rollers.
READ MOREThe Hot Air Blower is the heat source itself, the patented heater-less blower technology. This system is the complete package, that blower paired with Sonic XE air knives engineered specifically for surface drying, coating drying, and web processes.
125°F to 275°F, generated through the blower's own compression heat rather than an electric, gas, or steam heater.
In many cases, yes, particularly for drying water based coatings, paints, and inks, or for shrink film applications, where Sonic's heated XE air knives deliver the same result without the footprint or energy draw of a full oven.
Yes, that's part of the design intent. Because there's no heater element or open flame, the system avoids the fire and safety hazards associated with electric or gas heaters.
Up to 75%, since the system eliminates the inefficiencies and parasitic losses that come with electric, gas, or steam heating elements entirely.
