Koganei Fan Type ELF Series

Manufacturer: KOGANEI CORPORATION

Features

Advanced AC Systems: To begin with, the high-performance 200 Hz AC system enables an outstanding ion balance for stable industrial operations.
Precision Control: Specifically, the DTY-ELF14H model produces an excellent ion balance of $\pm$ 5V.
Long-Term Stability: Consequently, the high-frequency design ensures steady, long-term elimination of static electricity across various production environments.
Environmental Safety: Furthermore, the hardware maintains extremely low ozone production levels at less than 0.004 ppm to protect user health.

Wide Accessory Range: Additionally, the series supports a wide array of nozzle types to meet diverse industrial needs.
Target Flexibility: Therefore, the equipment effectively handles charge removal tasks ranging from pinpoint targets to wide area workpieces.
Remote Transport: Moreover, specialized blow type models enable ion transport using tubing and metal piping.
Resource Optimization: In a similar fashion, the air-saving type (DTY-ELK01-S) sucks in outside air for blowing to optimize factory resources.
Reduced Consumption: As a result, this unique airflow design significantly reduces overall air consumption during the elimination process.

Cleanroom Standards: To support sensitive applications, specialized models utilize charge removal needles made of special alloys.
Particle Control: Because of this material choice, the system dramatically reduces dust generation during operation.
Simplified Servicing: Similarly, the design facilitates simple connection and disconnection of the needle unit for routine care.
Tool-Free Access: Users can perform one-touch needle removal and attachment without needing any external tools.
Automated Cleaning: Furthermore, the DTY-ELF14 model features an automatic cleaning function that eliminates the need for manual needle maintenance.

Integrated Indicators: For better visibility, the hardware includes a balance indicator to confirm the ratio of positive and negative ions.
Airflow Management: Specifically, the airflow volume control allows operators to adjust the discharge smoothly via an integrated 5-level indicator.
Active Diagnostics: Additionally, an alarm output function detects problems with static discharge, high-voltage circuits, or internal fans.
Global Certification: Finally, every unit in the range remains CE marking compliant to ensure it meets international safety standards.
