Centrifugal Blower

Blower 20060

Name: Blower 20060 Centrifugal Blower
Brand: Ruifengda

The Blower 20060 uses a forward-curved centrifugal impeller in a 200 × 200 × 60 mm scroll housing to deliver high static pressure through filters, ducts and dense heatsinks — the right choice where a same-size axial fan would stall.

Product Overview

With its 200 × 200 × 60 mm scroll housing and forward-curved impeller, the Blower 20060 suits applications that need directed, pressurised airflow through restricted paths.

Each Blower 20060 is bench-tested after a complete aging cycle at our Shenzhen facility, and test records are retained by serial batch. Tell us your voltage, duty point and environment and the confirmed curve for your order will match the sample you approved.

Key Features

High static pressure output for filters, ducts and dense fin stacks
Forward-curved centrifugal impeller in UL94 V-0 plastic
Compact scroll housing with single or double inlet options
Ball-bearing versions for long life in any orientation
PWM speed control available on DC series
30 mm to 200 mm housing sizes to match your duct diameter

Note: Typical performance at nominal voltage. For designs near thermal limits we recommend a sample test at your enclosure's operating condition before release.

Frequently Asked Questions — Blower 20060

When should I choose the Blower 20060 blower instead of an axial fan?

Choose Blower 20060 when the enclosure has high airflow resistance — dense heat sinks, filters or long ducts. A centrifugal blower keeps steady pressure at restrictive duty points where an axial fan of the same size would stall.

Which way does Blower 20060 discharge air?

Blower 20060 is a forward-curved centrifugal blower: air enters axially and discharges radially through the scroll outlet, so plan the duct or vent direction accordingly. Outlet orientation can be customized.

Can Blower 20060 run at 24 V instead of 12 V?

Yes, Blower 20060 is offered in 5 V / 12 V / 24 V DC windings with matching speed and current. The same frame can be tuned for your supply rail at no tooling cost.

How noisy is Blower 20060 in real equipment?

Rated noise is measured at 1 m in free air. Inside a ducted enclosure, expect 3–6 dBA more; a PWM curve or rubber mounting pads usually reduces perceived noise noticeably.
