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

サンワ・エンタープライズ 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 source and is easy to install in production sites, 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 field of pneumatic equipment, established in 1971. For over 40 years, it has supplied products themed around "cooling," "blowing," and "air transportation" using compressed air, including the "Ultra-Low Temperature 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."

Small Pneumatic Equipment | Cylindrical Airflow Generator "Circle Blow"

This is a tool designed for blowing around pipes and cables. The air flow that blows out evenly at 360° enables draining, cleaning, and drying.

The cylindrical airflow generator "Circle Blow" is an air nozzle that emits a cylindrical stream of air at high speed from a thin slit, attracting and amplifying a large amount of surrounding air to create a powerful annular amplification flow. The amplified flow, which blows evenly and uniformly at 360°, is effective for draining, cleaning, drying, and cooling long products such as pipes, cables, and extrusion rods. The hole diameter ranges from 25mm to 180mm.

Spot Cooling Device | Ultra-Low Temperature Air Generator "Kolder" (with video)

A compact spot cooler that generates ultra-low temperature air with a maximum temperature difference of -75°C just by connecting compressed air.

The Kolder is a simplified spot cooler that applies the principle of vortex. Without using power supply or refrigerant gas, it discharges ultra-low temperature air with a maximum temperature difference of -75°C (at a supply pressure of 0.7 MPa, for model 190-75SV) just by connecting compressed air. A typical application of the generated cooling air is the removal of heat generated during the processing of materials such as metals and plastics, and it shows excellent effects particularly in the processing of hard materials and high-viscosity substances (such as titanium alloys, stainless steel, nickel alloys, and thermoplastic plastics). Additionally, the cooling effect on workpieces and tools leads to improved cutting speeds and extended tool life, making it particularly suitable for dry cutting of materials like magnesium alloys. Furthermore, it is effectively used as a cooling source for various spot cooling applications, such as preventing heat-related issues in electrical control boxes and various measuring instrument boxes, cooling molds, and cooling tests for semiconductors and PC boards. *For more details, please refer to the basic information and downloadable materials at the bottom of the page.

Cabinet Cooling Dedicated Cooler | Cabinet Cooler (Video Available)

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

The "cabinet cooler" reduces overheating inside NC or CNC cabinets, electrical control panels, motor boxes, surveillance cameras, various measuring instruments, etc., protecting precision machinery and measuring instruments from malfunction or damage due to overheating of electronic devices. Additionally, the automatic exhaust mechanism of the cabinet cooler keeps the inside of the cabinet in a pressurized state with cooling air at all times, preventing the intrusion of dust and mist from outside the cabinet and protecting electronic devices from contamination. By using a thermostat and solenoid valve, it is possible to regulate the temperature inside the box and reduce the amount of compressed air consumed.

Inline Air Transport Unit | Conveyor Back (with video)

It was manufactured for the purpose of air transport using compressed air. During operation, it does not require a power supply, making it suitable for use in explosion-proof environments.

The conveyor back is a device that enables air transport through a powerful vacuum pressure generated by compressed air as the power source. It has no moving parts and does not require a power supply, making it effective in environments where explosion-proof measures are required, as well as for the transfer and exhaust of gas and mist.

This is an actual existing generator.

[Pre-Purchase Campaign] You can view actual existing generators. *Limited to those considering purchasing a generator.

  • NEW
  • EVENT

Thank you very much for visiting our company website and catalog, and for your interest in our diesel engine generators. From customer surveys, the most common feedback we received was: - I want to see the actual generators that have been installed. - I want to see them operating under real load. - I want to hear the opinions of companies that have installed them. - I want to see the generators in operation before making a purchase. After all, it’s understandable to feel worried about purchasing a generator without seeing the actual unit first, right? As the saying goes, "Seeing is believing," so we will be holding this tour. It will take place in that area of the Kanto region, where summer temperatures exceed 40°C. We successfully operated our generators this summer as well, so we are confident in handling the heat (sweat). Additionally, it has been confirmed that our generators equipped with the world-leading "Scania engine" are "fuel-efficient." This will surely help reduce daily operating costs. Please note that while we will provide kind and courteous assistance, the meeting and dispersal will be at the site (transportation costs and other expenses will be borne by the customer), so please understand this in advance.

Scent presentation at a bar in Roppongi! Majesta Fragrance, a rental service for commercial aroma diffusers.

  • NEW
  • PRODUCT

We have introduced Majesta Fragrance at a bar located in Roppongi, enhancing the ambiance with scent. The first impression of a store is greatly influenced by the "fragrance" experienced the moment you enter. The model we introduced is the "MF-01," which costs 8,800 yen per month. Its cylindrical and slim design allows the diffuser to blend seamlessly with the bar's stylish interior without being intrusive. It takes up little space and elevates the adult atmosphere with a high-quality scent. It is chosen by establishments that prioritize the quality of their space, from restaurants to nightlife venues.
