Frequently Asked Questions
What cutout size do I need?
125mm x 125mm.
What's the difference between airflow with and without the filter?
156 m³/h without the filter, 108 m³/h with the filter fitted — the filter reduces flow slightly but keeps particles out.
Does it have overload protection?
Yes — built-in thermal overcurrent protection.
Can I pair this with a thermostat to control it automatically?
Yes — use in conjunction with a DIN rail mounted cooling thermostat such as the KNVT to switch the fan on automatically as temperature rises.
Does this come with a matching filter vent?
Yes — the KNF1500 filter vent grille shares this fan's cutout and overall dimensions, for a filtered intake/exhaust pair.
Industry Applications
- Control panel active cooling — forced airflow for heat-generating equipment
- OEM machine builders — standard IP54 filter fan for enclosure thermal management
- Server/equipment cabinets — reduces internal temperature rise under continuous load
