• This regulator is ideal for gas collection systems and supply facilities.
• It features a SUS pressure gauge cover to prevent rust formation from the pressure gauge.
• It also includes an internal filter to reduce internal leakage issues.
  ※ If you choose the W29-16 gasket for the inlet and outlet connectors, the filter will not be included.
• The gas inlet direction is selectable.
• The NT100B model has been redesigned with a new core height, making it easy to replace the old model (36mm).
  ※The mounting screw spacing is aligned with Unibus 100. If you are replacing it with JET-300 or Aurora 100, elongated holes will be required.Please refer to the external view diagram for detailed dimensions.
  ※ The NT100S model remains unchanged with a core height of 51mm.

• We do not provide installation for accessories. Please purchase separately and install them on your own.
• The mark at the end of the shape indicates the delivery time: ‘★’ indicates an in-stock item, and ‘no mark’ indicates a 14-day shipping item.
• We can also produce SUS products. For more details, please contact our sales representative.
• We can also produce other accessories. For more details, please contact our sales representative.
• Note 1) If you are using acetylene gas with W29-16(P), please purchase the W29-16 Aluminum Gasket separately.

Product Name Configuration

＜Notes for Selection＞

• If you choose ‘No Blow-off Valve’ with ‘P: Plug Stop’, please install a valve with similar functions such as a safety valve separately.
• If you select ⑤ Outlet Pressure Gauge Scale ’02 (0-0.25MPa)’, you can only choose ‘P: Plug Stop’ for ② Blow-off Valve. In that case, you can only choose ③ Inlet Pressure Gauge Scale ’16 (0-1.6MPa)’ or ’25 (0-2.5MPa)’ for the inlet pressure gauge.
• The outlet-side operating pressure is limited by the type of gas used. Acetylene is limited to 0.13MPa, and LPG is limited to 0.19MPa.
• When using carbon dioxide gas, take measures such as installing a heater.
• The scale of the outlet pressure gauge cannot be set to a larger range than that of the inlet pressure gauge. (Example: Inlet Pressure Gauge: 1.6MPa, Outlet Pressure Gauge: 2.5MPa)
• If you choose ’25(W29-16 Male Thread (P))’ for ⑦ Inlet Fitting and ⑧ Outlet Fitting, a filter is not included. (Please install a strainer upstream of the pressure regulator.)
• We can also produce high-pressure gas facility test items. For more details, please inquire.
