Overview

The general-purpose member of the small blower range. It moves air through a scroll and out of a directional outlet, which makes it useful when the airflow inside a product has to follow a defined path rather than fill the enclosure.

Options cover 12 V and 24 V with sleeve or ball bearings. Selection is usually set by the pressure the internal path adds, then by the space available around the outlet.

Where it fits

  • Instrument and analyser housings
  • Compact air handling modules
  • Equipment with a heatsink tunnel
  • Products that need directed internal airflow

Selection and installation notes

Check the outlet direction against the internal layout before ordering. Changing it later usually means a new bracket or hose.

Keep the intake clear of harnesses and labels; a partially covered intake costs more airflow on a blower than on an axial fan.

FAQ

What pressure can it hold?

It depends on the model and speed. Compare the static pressure column at the airflow you need, not the maximum figure alone.

Sleeve or ball bearing?

Sleeve for quiet, horizontal, moderate-temperature use; ball for higher ambient, vertical mounting or continuous duty.

Is 12 V or 24 V available?

Both appear in the specification table, with their current and airflow figures.

Can I get a sample?

Yes, for approval before production. Sample cost and lead time are confirmed with the quotation.
