Overview
A DC blower for the cases where an axial fan stalls: filters, fin stacks, long internal channels. The scroll converts speed into pressure, and the outlet can be connected to a short duct or a shroud.
The range lists airflow and pressure per model. Select on the pressure at your required airflow, then check the noise and the supply current.
Where it fits
- Filtered enclosures
- Heatsink tunnels
- Compact air handling modules
- Equipment with a constricted internal path

Selection and installation notes
A blower with a blocked outlet overheats its motor quickly. Make sure the path is open before applying power, and fit a screen where debris can enter.
If the duty point is close to the maximum pressure, choose the next size up. Running at the edge leaves no margin for a dirty filter.
FAQ
How is a blower rated?
By airflow at a given static pressure. The free-air figure alone does not describe what it will do in a restricted path.
Can it be ducted?
Yes, over a short distance. Long runs need a larger centrifugal fan.
What supply does it need?
DC voltage as listed per model. Check startup current against the supply.
Is a filter available?
Inlet screens and filters are selected separately and matched to the blower inlet.
