Hoffman Axial Fan 115V AC 100 CFM

This new Hoffman square axial fan delivers 100 cfm at zero static pressure for compact enclosure cooling. It operates on 115V AC power and draws 17 or 15 watts depending on frequency. The cast aluminium housing measures 4 5/8 inches wide and high with a depth of 1 33/64 inches. Ball bearings and polycarbonate blades provide a sound level of 37 or 41 decibels.

Suited for equipment racks needing a square 115V

Installers fitting a standard square cut-out in a compact enclosure will find the mounting footprint and power cord connection straightforward. The IP rating is none, so this unit is not for wet, dusty or outdoor environments. Buyers who need a higher ingress protection rating or a different voltage should look at other options.

Deciding spec: 115V AC square frame with 100 CFM

The critical match is the 115V AC supply combined with the 4 5/8 inch square frame and 100 cfm airflow at zero static pressure. If the enclosure requires a different voltage, a round mounting pattern or a higher airflow rating, this fan will not fit the design.

Questions about this item

What is the first performance limit reached when this fan runs continuously at 100 cfm?

The motor draws 17 watts at start-up and settles at 15 watts, so power consumption is the first sustained-use constraint.

How much noise and heat does the unit produce during all-day operation?

Sound level is rated at 37 dB low speed and 41 dB high speed; the cast-aluminium housing dissipates the 15–17 watt load without additional cooling.

What existing wiring must be in place for this 115 V AC fan to work?

A standard 115 V AC power cord connection is required; the fan ships with its own cord for direct mains hook-up.
