Square Axial Fan for Compact Enclosures
The Hoffman A4AXFN is a square axial fan built for equipment cooling inside compact enclosures. It operates on 115V AC power and delivers 100 cfm of airflow at .000 inches static pressure. The cast aluminium housing and polycarbonate blades are mounted with ball bearings for reliable operation. Lead wires provide the electrical connection.
Upgrade From Lower Airflow or Sleeve Bearing Fans
This unit replaces fans that cannot supply 100 cfm or that use sleeve bearings with shorter lifespans. The jump is worthwhile when the enclosure demands higher static airflow and the 37 to 41 sound level range is acceptable. It also supersedes fans lacking a cast aluminium frame for structural rigidity.
100 cfm Capacity With 17 Watt Draw
At 100 cfm the fan comfortably handles heat loads typical of dense component enclosures. Power draw sits at 15 to 17 watts, leaving headroom on standard 115V AC circuits. It runs out of capacity when static pressure rises above zero or when the application requires an IP rating for moisture protection.

Questions about this item
What are the cut-out dimensions for the 115 V AC square fan?
The fan is 4 5/8 inches wide and 4 5/8 inches high with a 1 1/2 inch depth, so the enclosure cut-out must match that square footprint.
How do I wire the 100 cfm axial fan into my enclosure?
Connect the two lead wires to a 115 V AC supply; the unit draws 17 watts at start-up and 15 watts running.
When should I plan to replace the ball-bearing fan?
The ball bearing and polycarbonate blades are rated for continuous equipment-cooling duty; replace the unit if airflow drops below 100 cfm or noise rises above 41 dB.
