Industrial cooling fan for 230V mains

The SXDOOL ORIX MRW18-TTA is a 180mm square metal-frame fan that runs directly from AC200/220/230 mains without a separate power supply. Its double-leaf impeller moves up to 190CFM at 2850RPM while drawing 48W. The unit weighs 2.3KG and uses a high-precision ball bearing rated for continuous counterclockwise rotation.

Check voltage wiring and mounting space

Verify that your installation can supply AC200/220/230 at 0.35/0.40A and that the 180x180x110mm housing fits the intended cut-out. The fan has no PWM or voltage-control lead, so speed regulation requires an external AC inverter or phase-cut controller. Ensure the exhaust path can handle the rated airflow without excessive back-pressure.

No bundled accessories or software included

The product ships as the bare motor assembly only; no mounting screws, finger guard, power cord or control interface are supplied. Integrators must provide their own wiring harness and safety grille to meet local electrical codes. The absence of a speed signal means monitoring software cannot report fan status.

Questions about this item

What comes in the box and do I need to buy a power cable or mounting screws separately?

The fan ships as a single 180×180×110 mm unit with a high-precision ball bearing and counter-clockwise blade rotation. No IEC power lead or mounting hardware is included, so source a suitable 230 V cable and four M4 screws yourself.

The listing shows 200, 220 and 230 V — which one should I select for UK mains?

The motor is rated for AC 200/220/230 V and draws 0.35 A at 200 V or 0.40 A at 230 V. UK mains sits at 230 V, so the fan will run at the higher current figure without any selector switch.

How loud is 38 dBA when the fan is running at 2850 RPM inside a typical case?

At 2850 RPM the unit produces 190 CFM with a stated 38 dBA. In a closed steel chassis the sound is a steady mid-frequency hum comparable to a quiet office, generally inaudible over a GPU under load.
