SKU CH-B6G2-G6HZQ

A 12 V, 4.56 W blower-style fan designed for projector cooling

  • 56 W rating keeps energy draw low
  • Blower design moves air through tight projector housings
  • New condition guarantees full factory performance

Compact 12V blower for projector cooling

This 12V blower delivers 4.56W of focused airflow for projector enclosures and tight chassis spaces. The radial design pushes air through restricted paths where axial fans cannot reach. It suits integrators replacing a worn original unit or building custom projection rigs.

Upgrade when the original blower fails

The part replaces a matching 12V blower of the same footprint and power draw. The jump is worth it when the existing fan stalls, whines or no longer clears the light path. Builders needing variable speed control or larger airflow volumes should look elsewhere.

Questions about this item

What mounting dimensions does the EF70251B1-C020-G99 blower require?

The EF70251B1-C020-G99 is a 70 mm square blower with 25 mm thickness; verify your chassis has a 70 mm × 70 mm opening and 25 mm clearance before purchase.

How do I connect the 12 V blower and what polarity mistake should I avoid?

Connect the two-wire lead to a 12 V DC header — red to positive, black to negative — reversing the wires will prevent the fan from spinning.
