An 80×80×38 mm AC axial fan is an 80 mm square, 38 mm-deep cooling fan that runs from an AC supply and moves air parallel to its shaft. It is
Choose a 24V DC cooling fan when your equipment already uses a stable 24V bus, which is common in industrial controls and automation. Choose a 48V fan when the system
A good electrical cabinet fan filter installation does more than hold a fan in a panel cutout. The intake and exhaust must create a useful path across the heat-producing equipment,
An intake filter fan and an exhaust filter normally work together rather than compete for the same job. The intake filter fan contains the powered fan that draws ambient air
You can estimate the airflow for an electrical enclosure from two values: the heat that must be removed and the temperature rise you can allow above ambient. That calculation gives
A cabinet fan can keep running while its cooling performance quietly disappears. As dust loads the filter, pressure drop rises and airflow falls. The fan may still sound normal, but
IP54 and IP55 filter fans have the same level of dust protection, but they are tested against different levels of water exposure. The first digit, 5, means the enclosure is
When you compare a 50Hz vs 60Hz cooling fan, frequency is not just a regional label. On many conventional AC fans, it changes motor speed and therefore affects airflow, static
When comparing a 115V vs 230V AC fan, neither voltage is automatically better. The correct choice is the one that matches the voltage and frequency available at the fan terminals
Fan speed and airflow are closely related, but they are not interchangeable specifications. RPM tells you how fast the impeller turns. CFM or m³/h tells you how much air moves.
Cooling fan power consumption looks like a simple specification, but it is easy to read the wrong number. A buyer may compare voltage, current, airflow, and wattage from several fan
Open a fan datasheet and the performance graph can look like the least friendly part of the page. It is actually the part that tells you what the fan will
