Air Water Sol Inc. commands the No. 3 share of the domestic aerosol industry in terms of aerosol product (spray product) production volume. Air Water Sol was created through the merger and acquisition of four manufacturers possessing unique technologies, and the strength of Air Water Sol Inc. lies in its production system incorporating four highly specialized domestic plants as well as R&D capabilities in a wide array of fields. A diverse range of products is supplied to OEM, particularly coating materials and automotive parts (which, in both cases, Air Water commands a large market share) as well as cosmetics and quasi drugs (which are growth markets).
　Air Water has also been actively developing products under its own brand in recent years which are tailored to a range of needs; such products include "Whitening UV Protection Spray," "Mild Hand Soap," "Tepure (disinfectant and washing solution)," and "Super Fresh ECO2 (CO2 gas blower)."

　Air Water Mach Inc. is a specialized manufacturer of industrial-use rubber, manufacturing and selling a variety of rubber molded products and resin molded products geared towards general industrial machinery, home electric appliances, automobiles and medical products, with its most notable product being ultrahigh-performance rubber O-rings for semiconductor and LCD manufacturing systems.
　All of these products from high value-added products to mass production products, are flexibly manufactured at production facilities in Japan (Nagano, Ishikawa) and in China (Fujian, Dalian), taking advantage of a strong production system incorporating molding and materials and centered on compounding technology, molding technology and composite technology cultivated over many years.

　Air Water NV Inc. develops business that applies a uniquely developed "gas activation process," based in the advanced gas technology maintained by the Air Water Group, to metallic surface hardening treatment. Air Water NV uses the three technologies of "NV nitriding," which provides high quality surface treatment for various steel materials, "Pionite," which increases the hardness of stainless steel without compromising corrosion resistance, and "MYZOOL," which enhances solvent resistance through the creation of a chromium nitride layer, to provide unparalleled quality that satisfies the stringent demand characteristics of automobile parts and home electric appliances, for which the need for efficient resource utilization and size and weight reduction is increasing. In addition to contract treatment business in their plants in Hyogo Prefecture and Gunma Prefecture and on-site treatment at user plants, Air Water NV is also performing heat treatment at its hubs in Thailand and the Philippines.

　ECOROCA® is a 100% compound, recycled material made from used wood and waste plastic. This new, environment-friendly material, which provides superior durability together with the natural feel of wood, has found its primary applications in such fields as outdoor wooden deck construction. Because of the superior safety provided by ECOROCA®, it is particularly valued as a high quality construction material suited to public facilities and has been adopted in such construction projects as the building of a one-kilometer boardwalk at Odaiba Seaside Park.
　In 2011, Air Water introduced a "heat-blocking deck" which helps keep surface temperature down, even in summer, and it is being increasingly adopted into homes, schools, rooftop gardens and elsewhere. With the Nagano Plant, which produces high-grade product lines and possesses public certification (JIS A5741 certification), as the key driving force, Air Water will continue to release new and innovative products onto the market nationwide.
