Product Overview

The FK3G225-48PY-90 is a compact DC centrifugal fan with an integrated 90° bracket, designed for space-constrained ventilation and cooling applications. Featuring a backward-curved plastic/fiberglass impeller (225mm) and optimized for static pressure (up to 514 Pa), it delivers focused airflow while operating quietly at 68.3 dB(A). Its 48VDC brushless motor (BLDC92) offers efficient performance with industrial-grade protections.


Core Features

  1. Space-Optimized Bracket Design
    The integrated 90° mounting bracket enables flexible installation in tight corners or equipment enclosures, ideal for confined industrial spaces where traditional fans won't fit.

  2. High-Pressure Centrifugal Performance
    Generates focused airflow against resistance (up to 514 Pa static pressure) using a 7-blade backward-curved impeller – perfect for ducted systems or heat-dense environments.

  3. Precision Control & Robust Protections
    Supports 0–10VDC or PWM speed modulation with real-time RPM feedback (FG: 4 pulses/rev). Built-in safeguards include thermal shutdown, voltage lockout, and reverse-polarity protection.


Applications

  • Enclosed Equipment Cooling: Rack-mounted servers, power converters, or control cabinets requiring directed airflow.

  • Ducted Ventilation Systems: Spot cooling in manufacturing lines or exhaust pathways with space constraints.

  • Compact Machinery: Integration into medical devices, packaging equipment, or automation systems.


FAQ

Q1: What's unique about the bracket design?
It features a fixed 90° angle for corner or wall mounting in space-limited installations.

Q2: How does airflow direction work?
Air exits radially ("all around") from the impeller housing, suitable for duct attachments.

Q3: Can I adjust the bracket angle?
No, the 90° angle is fixed per the design.

Q4: Is this fan suitable for outdoor use?
With IP44 protection, it resists dust and water splashes but isn't rated for heavy rain.
