Product & Specs

Available dimensions depend on the selected series. Browse the product list and verify the complete frame dimensions, thickness and mounting drawing for your exact model before ordering.

The catalog includes different DC voltage versions. Check the rated voltage and operating voltage range on the exact model page; do not apply the voltage range of one model to another.

HD (High-speed), MD (Medium-speed) and LD (Low-speed) are pre-set speed variants of the same physical fan model. HD delivers the highest airflow and static pressure at a higher noise level, LD runs quieter with reduced airflow, and MD sits in between. This lets you pick the performance/noise balance that fits your system without changing the fan footprint.

Bearing options depend on the model and configuration. Confirm the ordered bearing code, mounting orientation, ambient temperature and duty cycle against the model-specific documentation.

Service-life ratings depend on the exact model, bearing, test temperature, mounting and duty cycle. Request the relevant life rating and test conditions; a general hour figure should not be assumed to apply to every fan.

Ingress protection must be confirmed for the exact model and ordered configuration. Share dust, moisture and outdoor exposure requirements, and ask for the relevant rating and supporting documents before selection.

Share the required airflow at your system pressure, installation space, supply voltage and noise limit. Ask which existing model or configuration can meet the operating point, and confirm any custom development separately.

A free-air CFM number only tells you how much air the fan moves with nothing in its way. Once it’s pushing air through a filter, heat sink, narrow duct, or a tightly packed enclosure, static pressure — not free-air CFM — determines real performance. Two fans with identical CFM ratings can have very different static pressure curves, so the one with lower static pressure will lose much more airflow under resistance. Share your enclosure’s actual airflow path (filters, ducting, obstructions) and we can recommend a fan matched to your real back pressure, not just the datasheet’s best-case number.
