The "Prince Changer" is a semi-automatic switching device for general industrial gases. It automatically switches between the left and right gas supply lines, allowing for continuous and long-term gas supply. We offer two types: one for collective devices and one for wall mounting, so you can use it appropriately depending on the installation location. Additionally, by using the optional pressure gauge with contact and the Prince Alarm warning device, you can be notified via a buzzer and lamp when the pressure in the supplying line becomes low. 【Features】 ■ Automatically switches between the left and right gas supply lines ■ Allows for continuous and long-term gas supply ■ Available in two types: for collective devices and for wall mounting ■ Can be used appropriately depending on the installation location *For more details, please refer to the PDF document or feel free to contact us.

The "Prince Changer PC250B-LP-M/PC250B-LP-P" is a semi-automatic switching device of low pressure and high flow type. Compared to conventional models, it achieves outstanding flow performance (250L/min). The purity maintenance performance has been improved by covering the diaphragm with Teflon. Additionally, we also offer the medium pressure (0.7MPa) supply type "Prince Changer PC150B-MP-M/PC150B-MP-P" in our lineup. 【Features】 ■ Achieves outstanding flow performance compared to conventional models (250L/min) ■ Available in two types: manifold type (M) and panel type (P) ■ Purity maintenance performance improved by covering the diaphragm with Teflon ■ We provide a stepped valve to assist with installation into existing equipment ■ A variety of options available, including pressure gauges with contacts and alarm panels *For more details, please refer to the PDF materials or feel free to contact us.

The "Stainless Changer SC-930SSA" is a semi-automatic switching device based on the highly reliable and proven "S-LABO regulator." It is a low-pressure type that uses a stainless steel diaphragm, making it suitable for high-purity gases, including standard gases and laser gases. The two-stage pressure reduction structure allows for stable supply of outlet pressure. Additionally, there is a "Stainless Changer SC-930SSY" available in the lineup, which is a medium-pressure (0.7MPa) supply type. It automatically switches between the left and right gas supply lines, enabling continuous gas supply for extended periods. 【Features】 ■ Semi-automatic switching device based on the highly reliable and proven "S-LABO regulator" ■ Uses a stainless steel diaphragm ■ Capable of continuous gas supply for extended periods ■ Stable outlet pressure supply due to the two-stage pressure reduction structure ■ Does not use electricity as a power source for automatic switching, making it suitable for flammable gases *For more details, please refer to the PDF document or feel free to contact us.

The "Prince Changer PC150S-MP-M/PC150S-MP-P" is a semi-automatic switching device for medium pressure (0.7MPa) supply type. It can supply up to 0.7MPa while being excluded from the category of "high-pressure gas manufacturing equipment," and it now features a highly anticipated stainless steel version for medium pressure semi-automatic switching. The two-stage side pressure reducing valve adopts a newly designed low-pressure loss specification, achieving a flow rate of 150 to 250 L/min. 【Features】 ■ Excluded from "high-pressure gas manufacturing equipment" ■ Achieves a flow rate of 150 to 250 L/min ■ Available in two types: manifold type (M) and panel type (P) ■ Improved purity maintenance performance ■ Various options available, including SUS contact pressure gauges and alarm panels *For more details, please refer to the PDF document or feel free to contact us.
