4inch Axial Fan Kit Moonjor – Exhaust Extractor with Switch, 119m³/h

Description

Product Overview

The Moonjor 4inch Axial Fan Kit is engineered for high‑performance air movement in a compact form factor. Operating on a standard 110‑120V line, the fan draws only 18W while delivering an impressive 119 m³/h (approximately 40 CFM) of airflow at 2700 RPM. A copper motor paired with precision‑engineered oil ball bearings provides smooth, long‑lasting rotation, while the IP44 rating guarantees protection against water splashes and dust ingress, making it suitable for both indoor and semi‑outdoor environments. Noise levels are kept to a modest ≤40 dB, ensuring quiet operation in noise‑sensitive settings such as laboratories, studios, or home grow tents. The unit includes a convenient on/off button on a US‑style 3‑pin plug, allowing instant control without the need for external switches or relays. Its robust ABS housing and reinforced tailpipes can handle temperatures from –20 °C to 70 °C, and the dual‑tail design enables flexible installation either as an intake or exhaust fan. Dimensions of 11.61 × 6.85 × 6.14 inches and a weight of 2.8 lb make the kit easy to mount on walls, frames, or within ductwork.

Usage

This fan kit excels in a wide range of applications where reliable ventilation is essential. In indoor horticulture, the 4inch axial fan efficiently extracts hot, humid air from grow tents, helping maintain optimal temperature and CO₂ levels for healthy plant growth. For HVAC systems, it can be integrated into residential or commercial ductwork to boost air circulation, improve indoor air quality, and reduce strain on larger blower units. The fan’s compact size and low power draw also make it an excellent choice for 3D printer enclosures, where consistent airflow prevents overheating of print heads and reduces filament warping. Additionally, the fan can be installed in laundry rooms to vent dryer exhaust, in workshops to clear dust and fumes, or in small greenhouse structures to promote uniform temperature distribution. Its waterproof rating allows occasional exposure to moisture, such as in humid basements or near water‑cooled equipment, without compromising performance.
