New release of "Stainless Steel Circle Blow" to enhance rust prevention effects for drainage applications and more.

サンワ・エンタープライズ

The "Stainless Steel Circle Blow" is a nozzle that, by simply connecting compressed air, draws in a large amount of surrounding air from the rear and generates a uniformly amplified ring-shaped airflow. While conventional products were made of aluminum, the new product improves rust prevention for applications such as draining by using stainless steel as the main material. The Circle Blow, which does not require a power supply and is easy to install in production environments, is effective for blowing, draining, and drying long workpieces such as metal and plastic pipes, wires, cables, and extruded products. It is available in three sizes with effective inner diameters of 75 mm, 125 mm, and 180 mm. Sanwa Enterprise Co., Ltd. is a pioneer in the pneumatic equipment manufacturing industry, founded in 1971. For over 40 years, it has supplied products themed around "cooling," "blowing," and "air transport" using compressed air, including the "Cryogenic Air Generator Kolder," to manufacturing sites in various fields. On the special page, we introduce various products of Sanwa's pneumatic equipment, highlighting three features: "cooling," "blowing away," and "transporting."

No power supply needed. This is a cabinet cooling (heat dissipation) dedicated spot cooler that operates solely on compressed air.

【Features】 ● Compact and lightweight; extremely easy to install and operate ● No power supply needed; operates on compressed air from the factory ● Does not use any refrigerants or chemicals
Inline Air Transport Unit | Conveyor Back (with video)
It was manufactured for the purpose of air transportation using compressed air. During operation, it does not require a power supply, making it suitable for use in explosive environments.

【Features】 - Super powerful air transport just by connecting compressed air - Easy installation and handling - Durable material, maintenance-free - Choose between aluminum and stainless steel according to application
Small Pneumatic Equipment | Air Volume Amplifying Type "Line Blow" (Video Available)
The Coanda effect generates a thin, uniform curtain-like laminar flow. Its applications are diverse, including drainage, drying, heat dissipation blowing, and cooling.

■Main Features - Generates a uniform air curtain simply by connecting to a compressor's compressed air - Amplifies air volume by drawing in surrounding air through an amplification mechanism, significantly reducing noise - Simple and robust structure reduces maintenance effort - Two types available depending on application: aluminum and stainless steel ● For more details, please contact us or download the catalog.
Small Pneumatic Equipment | Air Amplification Air Blow Nozzle "Round Blow"
Suction and blow, two functions in one device. It is a tool that enables powerful vacuuming and blowing.

【Features】 ■ Supports two functions: vacuuming and blowing ■ Adjustable air discharge volume and air pressure ■ Easy to install and maintenance-free
Small Pneumatic Equipment | Air Volume Amplifier "Jet Blow"
It is small enough to fit in the palm of your hand, yet capable of powerful vacuuming and blowing.

Typically, a 6mm diameter air tube utilizes the full output of a 10 horsepower (7.5KW) compressor, and the noise level exceeds 100 dBA. The "740 Series" amplifies compressed air by four times, allowing for the same blowing effect with only a quarter of the compressed air when using a 6mm nozzle, while also reducing the noise level to 76 dBA. Additionally, the powerful vacuum pressure generated at the rear can be applied to the suction and exhaust of fumes, toxic gases, air, and the air transport of powders. By simply loosening the lock ring and rotating the discharge section, the internal slit width can be freely adjusted, allowing for optimal operating conditions in conjunction with the adjustment of supply pressure. It is ideal for replacing conventional nozzles with a diameter of 4mm or more.
Nozzle | Air Amplifying Air Nozzle
"Blow," "drain," "dry" - spot blow with amplified air.

We offer a lineup ranging from pencil-type to flat-type. Each of them creates an amplified blow flow from the compressed air consumed, demonstrating effectiveness in cooling, blowing away, and other applications.
