Overview
A small-frame DC fan for enclosures where the heat load is modest and the opening is fixed. The series is listed with airflow, static pressure and noise per model, which makes it possible to compare variants on the number that matters for the installation.
It sits between the quiet range and the high-flow range: more airflow than the quiet models, less noise than the high-flow ones, with 12 V and 24 V options.
Where it fits
- Small control and instrument enclosures
- Camera and sensor housings
- Portable power and charging units
- Compact machine covers

Selection and installation notes
Check the static pressure if the fan discharges through a grille or a filter. At this size, a dense mesh can remove a large share of the free-air airflow.
Keep the intake and exhaust areas clear. A fan pressed against a wall or a cable bundle loses volume without sounding any different.
FAQ
How do I compare the models?
Compare airflow at the static pressure your enclosure creates, then check noise. The table lists all three so the trade is visible.
12 V or 24 V?
Use the rail you already have. At the same power a 24 V fan draws half the current, which helps on long cable runs.
Can it be used with a filter?
Yes, but expect lower delivered airflow. Size with the filter fitted rather than on the free-air figure.
Is a sample available?
Yes, for approval before a production order. Sample cost and lead time are confirmed with the quotation.
