The "Anywhere Draft" tabletop gas removal device was developed with the aim of reducing the risk of gas exposure for researchers. Please install the "Anywhere Draft" near areas where organic solvent odors or irritant smells are generated. It reduces the risk of exposure to organic solvents and VOC gases. Features: - Powerful suction - Excellent formaldehyde removal performance (approximately more than 10 times the adsorption capacity of activated carbon filters. For certain types of gases, it can adsorb dozens of times more.) - Compact design for easy portability, making it easy for anyone to carry. - Combines both chemical and physical adsorption. It also removes the odor of formaldehyde. With a compact design weighing about 5 kg, it can be easily transported by women to secure work areas as desired. Despite its small size, it efficiently and powerfully sucks and removes formaldehyde through cleverly designed airflow control. The dedicated formaldehyde filter installed in the device exhibits strong removal performance. It can also be used as a countermeasure against exposure to various chemical and pharmaceutical chemicals. Risk assessment measures for the work environment can be easily conducted.

• Deaeration device

"Continuous vulcanization" refers to the process where traditional O-rings and similar items without molds were connected using adhesive materials like extruded rubber cords. This method had issues with the strength, heat resistance, oil resistance, chemical resistance, and sealing performance of the adhesive joints. Continuous vulcanization O-rings are molded through press vulcanization, eliminating the need for any adhesives. Therefore, they possess performance characteristics similar to those of standard molded products. Continuous vulcanization molding is a technology for producing special dimensions that are not covered by JIS or AS standards, and since it does not require molds for single items or small lots, it allows for the production of large-diameter O-rings at low cost and with short lead times. Because molding is performed using various dedicated facilities for continuous vulcanization, the finish, appearance, and dimensional accuracy are stable, and since the same materials as standard products are used, there are no occurrences of trouble.
