About Toyobo AC Apparatus Department

Development of the Activated Carbon Fiber K-FILTER™

The Toyobo Group has been engaged in the development of air purification environmental materials for over 30 years. The first was the K-FILTER developed at the Toyobo Research Center in 1974 as the first activated carbon fiber filter mass produced worldwide. At that time, Japan was seeking pollution countermeasures and energy conservation policies, and Toyobo wanted to respond those social needs using fibers.

"The K-FILTER absorbs solvents quickly, and has a high solvent absorption capacity. It shows almost no performance loss after repeated desorption, and the desorption period is shorter than that for conventional granular activated carbon. To maximize the advantages of this material, we took an integrated approach covering everything from development of the absorbent, and development and manufacturing of the apparatus, all the way through to the apparatus sales and maintenance." — AC Operating Department Senior General Manager Yasuhiro Iizuka

"The integrated approach from materials development through to apparatus manufacturing, sales and maintenance is an unusual business model inside Toyobo. However, it is precisely because we have an integrated approach, including Toyobo Group companies, that we can meet the needs of diverse users, and that has become our company's strength."
— AC Apparatus Department General Manager Kazuyuki Kawata

Toyobo has developed gas treatment products starting with K-FILTER VOC Recovery Apparatus developed maximizing the advantages of the K-FILTER, Honey-Rotor™ Absorption and Concentration Apparatus which uses an activated carbon zeolite honeycomb absorbent, and VOC recovery equipment which also uses that type of absorbent.

VOC Gas Treatment Apparatus wins High Market Share

In Japan, the regulation of VOCs was strengthened with the 2006 revisions to the Air Pollution Control Act. This revision has led to increased VOC gas treatment apparatus demand in the printing, coating, solar cell and other industries following a grace period, which ended in March 2010.

To provide our customers with the optimal VOC gas treatment apparatus, Toyobo Group companies are working together to offer comprehensive services covering everything from analyses of exhaust and operating conditions through to proposals on absorbent choice, structure, treatment method and apparatus. We also support customers with maintenance and renewal services after delivery. Our comprehensive approach running from start to finish has been well received. Toyobo Group VOC gas treatment apparatus has been adopted at numerous manufacturing plants, and Toyobo has now earned a high share of the absorption-type VOC gas treatment apparatus market.

The Toyobo Group aims at the development of compact low-cost apparatus, reductions in running costs, and the use of the heat energy generated in the treatment process to provide solutions that are both ecological and economical. Toyobo takes pride in helping to improve manufacturing environments with our VOC gas treatment apparatus which supports manufacturing processes.
