EC (AC/DC) Fan

EC 12032 Blower

Name: EC 12032 Blower EC (AC/DC) Fan
Brand: Ruifengda

The EC 12032 Blower pairs a brushless DC motor with a wide 100–277 V AC input, delivering DC efficiency on AC power. In its 120 × 120 × 32 mm frame it offers stepless speed control and substantially lower energy use than an equivalent AC fan.

Product Overview

A 120 × 120 × 32 mm EC hybrid fan, the EC 12032 Blower typically consumes around half the power of an equivalent AC unit while holding speed far more stable across supply fluctuations.

Each EC 12032 Blower 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

Wide 100–277 V AC input with brushless DC motor efficiency
Stepless speed control via PWM, 0–10 V or resistance signal
Up to 50 % lower power draw than comparable AC fans
Soft-start, locked-rotor protection and tach feedback built in
Dual-ball bearings for 50,000 h+ continuous operation
Ideal for energy-regulated projects and inverter-driven systems

Note: Specification values are representative; measured performance depends on system resistance and ambient temperature. Ask for the measured P-Q curve with your sample.

Frequently Asked Questions — EC 12032 Blower

What is the difference between the EC version and the AC/DC version of EC 12032 Blower?

The EC version of EC 12032 Blower uses a brushless DC motor with integrated electronics: higher efficiency, lower power draw at the same airflow, wide voltage input and controllable speed — ideal for equipment that runs long hours.

How do I control the speed of EC 12032 Blower?

EC 12032 Blower supports PWM (1–10 kHz), 0–10 V analog and NTC temperature-controlled modes. Speed curves can be programmed at our factory to match your thermal profile.

What input voltage range does EC 12032 Blower accept?

Standard EC input is 100–240 V AC or 12–60 V DC depending on the variant. Wide-input versions tolerate unstable grids and generator supplies — confirm the range with us before ordering.

Does EC 12032 Blower have tach output and alarm signals?

Yes. Tach (FG), locked-rotor alarm (RD) and soft-start options are available on EC 12032 Blower; specify the signals you need when requesting a quotation.
