Features of Pleated Filters in Flow Machine Engineering 1. **Compact** We have developed and provided filters that boast approximately 20 times the filter cloth area compared to conventional bag filters. This is the source of our overwhelming suction power! The amount of air that can be processed is different from other companies!! 2. **Maintenance-Free** Automatic regeneration through powerful supersonic impulses prevents clogging. When releasing compressed air, a supersonic impulse (shock wave) is applied to the filter to strongly dislodge dust particles that have adhered to it. This significantly reduces the effort and time required for replacing and maintaining conventional bag filters. With automatic filter cleaning, clogging is less likely, allowing for continuous operation without maintenance. 3. **High Purity** The outlet cleanliness of our standard filters is below 0.1mg/m3, achieving a high level of cleanliness equivalent to atmospheric dust levels. Furthermore, our PTFE filters, designed for fine particles, achieve cleanliness below 0.01mg/m3, comparable to clean room standards, and are used in nuclear, aerospace, bio, and precision electronics fields. A high level of cleanliness equivalent to atmospheric dust levels is achieved.

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.

■ Non-Leak Duct (Positive Pressure Use) ● Non-Leak Duct (Packing Type) (Patent Application No. 2015-38261) Measured value φ2500 at 8kPa with a maximum leakage rate of 0.1m³/min (per one fastening connection point) Available in φ800 to φ2500, standard length of 10m ● Small Diameter Non-Leak Duct (Patent No. 4917069) This is a duct for positive pressure use. Air leakage is almost zero. With a leakage rate of 1/3700 compared to conventional ducts, it is an excellent air duct for long-distance small cross-section shield and tunnel ventilation. Available in φ300 to φ700, standard length of 10m ■ Pita Joint Duct (Negative Pressure Use) This is a duct for negative pressure use. Air leakage is almost zero even at -80kPa. With low friction resistance and good long-distance air delivery characteristics, it enables significant energy savings and allows for a smaller blower size. Compared to conventional steel pipes, the outer diameter of the joint section is smaller, allowing for space-saving installation. It offers excellent cost performance for methane gas exhaust, long-distance shields, small cross-section tunnel mechanical excavation, TBM, and more.

We would like to introduce a case study from Ryuki Engineering, which proposes a reduction in the running costs of water treatment. We received a request from a precision parts/plating factory that wanted to reduce costs by purifying river water for use as cleaning water for precision electronic components. [Case Study] ■ Industry: Precision parts/plating factory ■ Challenge: The factory has been using tap water for cleaning precision electronic components, but the water bill is high. They want to reduce costs by purifying river water for use as cleaning water. Our company used "ECO Clean" to purify the turbidity of river water to the level of tap water. By enabling the use of river water, we provided water at one-tenth the price of tap water, achieving a 90% reduction in tap water costs through purification and utilization. *For more details, please refer to the PDF document or feel free to contact us.
