Product Overview

The Booster 12038 (Version 2) targets the middle ground between axial airflow and centrifugal pressure: a 120 × 120 × 38 mm booster with steep blade pitch for resistance-heavy paths.

Every Booster 12038 (Version 2) passes automated winding inspection, dynamic balancing and a full aging cycle before it leaves our Shenzhen factory. When you request a sample we verify the operating point against your system's resistance curve and can adjust speed, voltage range or output leads without tooling charges on standard sizes.

Key Features

Dual-ball bearing as standard for high-temperature, long-hour duty
Static pressure significantly higher than same-size axial fans
Reinforced impeller balanced to G6.3 for stable high-speed running
Ideal as an in-line booster on existing ducting
12 V / 24 V DC input with PWM control option
Tach signal available for airflow monitoring

Note: Figures shown are standard-configuration values. Custom speed bins, voltage windows and bearing grades are quoted against your requirement.

Typical Applications

Ventilation ducts & tunnels Chassis positive-pressure systems Range hoods & exhaust lines Equipment cabinet forced air Aquarium & hydroponics Long restrictive airflow paths

Frequently Asked Questions — Booster 12038 (Version 2)

What makes Booster 12038 (Version 2) a booster fan?

Booster 12038 (Version 2) uses a high-static-pressure impeller and stator design that keeps airflow under strong back pressure — suited to dust filters, long ducts, range hoods and dense radiators where ordinary fans lose most of their CFM.

Can Booster 12038 (Version 2) be daisy-chained in series?

Yes, two Booster 12038 (Version 2) units in series roughly add their static pressure capability. Mount them with a short spacing section and confirm the second fan's inlet conditions with our engineers.

What protection options exist for Booster 12038 (Version 2)?

Auto-restart, polarity protection, tach and alarm signals are available. For humid or oily environments, conformal-coated PCBAs and IP54 grilles can be added.

What is the lead time and MOQ for Booster 12038 (Version 2)?

Samples ship in 5–7 working days; volume MOQ is typically 200–500 pcs depending on configuration. Custom voltage, speed or connector versions need 10–15 days for first samples.
