It absorbs the oil smoke generated during the dismantling of large-diameter shield machines. The filter is of the regenerable type, so filter replacement is not necessary.

●Air volume: 70m³/min ●Application: Local dust generated in tunnel and shield construction. Suitable for all dust control measures such as building demolition and renovation work.

Dust generated during work will be collected under the workbench. By suctioning dust from the work surface, it prevents dust dispersion and keeps the work area clean. The large table surface is strongly suctioned with a downflow of approximately 1m/s. The dust collection unit is placed separately, allowing for flexible layout and maintenance-free operation. By installing a dust-proof sheet at the work opening as an option, even stronger suction can be generated. The dust-proof sheet can also be made movable, allowing for flexible use of the workspace.

- Cleanliness level of 0.05 mg/m³, optimal sealing. - Reduced cross-sectional dimensions for TBM, compact and lightweight, making it suitable for small cross-section NATM as well. Additionally, we can design it to match TBM and subsequent carts. - The machine section is completely refreshed, allowing for low airflow, making it economical. - The fan power is small, and it operates at ultra-low noise (79 dB). - Teflon-coated filter + air pulse cleaning for maintenance-free operation, mist inclusion is also acceptable. - When combined with a cooling unit, it can provide dehumidified air conditioning. *Please feel free to contact us for more details.*

The "HF Series" is a smoke collector that captures oil mist, black smoke, and fumes generated during the dismantling of shield machines. It collects smoke such as welding fumes with a high-performance filter, improving the working environment. Optionally, it can also adsorb and deodorize gases. *For more details, please feel free to contact us.*

The "PC-20HF" is a diesel smoke filter that adsorbs diesel black smoke, welding fumes, and other pollutants generated locally. With a filter heat resistance of 130°C, it can adsorb exhaust gases near the vehicle's muffler, improving the on-site environment. *For more details, please feel free to contact us.*

Before the formal order (specification review stage), it is possible to conduct a [real machine test] using rental equipment. We have a large number of rental dust collectors due to our long-standing rental business with manufacturers, allowing us to verify appropriate air volume and filter performance. Before adoption, it is possible to conduct a full-scale real machine test with rental units ranging from 10 to 3,000 m³/min to confirm performance and effectiveness (under normal temperature conditions). For customers who are unsure about usage conditions or dust characteristics, we also offer preliminary measurements of dust quantity and investigations of particle size distribution. ■ Flow of Implementation ■ Specification Review: Hear usage conditions and requests. Confirm usage situation and surrounding environment through on-site investigation. ↓ Initial Design: Submission of proposal drawings and estimates. ↓ Formal Order ↓ Detailed Design: Creation of production drawings, ordering of parts, process management, and review of audit items. ↓ Production and Assembly: Assembly, production, trial operation, and quality inspection. ↓ Delivery: On-site installation, trial operation, and submission of documentation. *Please contact us for details about the demo.*
