SKU CH-KM9R-MAM7Z

A 115 VAC axial fan delivers 190 to 235 CFM at 2800 to 3500 RPM for enclosure cooling

  • Product typeRound
  • Delivers 190 to 235 CFM airflow for effective equipment cooling
  • Operates on standard 115 VAC 50/60 Hz power supply
  • Low 46 dB sound level suits noise-sensitive environments
  • cULus listed for verified safety compliance
  • Compact 2-inch depth fits tight enclosure spaces

Application & Purpose

The Wiegmann axial fan delivers 115 VAC airflow for equipment enclosures that require vertical mounting. Its round plastic and steel housing fits standard cut-outs and the lead-wire connection simplifies wiring inside cabinets. The unit is cULus listed for equipment-cooling applications. It serves installers who need a compact, enclosure-rated fan without an integrated guard.

Sustained Airflow Behaviour

At zero static pressure the fan moves 190 CFM on 50 Hz and 235 CFM on 60 Hz while drawing 26 W and 35 W respectively. Speed rises from 2,800 RPM to 3,500 RPM between the two frequencies, maintaining consistent cooling across both mains standards. The non-metallic blades and sleeve bearing design support continuous duty in enclosed environments.

Thermals, Noise & Power

Sound output measures 46 dB under normal operation, a level suited to equipment rooms rather than occupied spaces. Power consumption stays at 26 W on 50 Hz and 35 W on 60 Hz with no IP-rated sealing, so the fan relies on the enclosure for environmental protection. Vertical mounting ensures unrestricted intake and exhaust paths.
