| Model | Primary catalyst unit (suing a cubic type metal honeycomb catalyst) |
| Material | Structural support： stainless steel wheel (Fe-20Cr-5Al) Wash-coat： γ-alumina (rare earth element of stable type) Catalytic active material: Pt |
| Dimensions | Differ depending upon models Catalyst cell density: 260 CPSI (cells per square inch) |
| Appropriate operating temperature | To obtain specified purification performance: min. 300℃ To maintain specified catalyzing performance: below 800℃ |
| Purification characteristics | Surface-supported type catalyst having very large surface area and highly active purifying performance due to the catalytic precious metals existing on catalytic surfaces. (See graph 1.) |
| Pressure loss | Use of 50µm-thin plate realizes a very small pressure loss. (See graph 2.) |
| Thermal conductivity and thermal capacity | Use of stainless steel structural support brings about high thermal conductivity and low thermal capacity, thus making it possible to achieve very quick temperature rise to the catalyst operating temperature. |
| Mechanical strength | Strong against vibration, heavy load, and physical and thermal shocks (caused by sudden change of temperature). |
| Maintenance | Cleaning with neutral detergent allows normal performance and long life to be maintained. |
