Ex-government Allens Industrial Products NPU 4000 Centrifugal Fan Unit - 5200 M3/HR Airflow - 240V 50Hz - Minimal Hours
Overview
This is a professional-grade centrifugal fan unit manufactured by Allens Industrial Products, a respected Australian equipment supplier. The NPU 4000 is engineered for high-volume air movement applications including dust collection, ventilation systems, and industrial air handling. With a certified airflow capacity of 5200 cubic metres per hour and robust construction, this unit is built for demanding workshop and industrial environments. The machine has been performance tested and certified to BS 8520-2:2009 standards, providing confidence in its operational integrity.
The unit presents in excellent condition with minimal operating hours. The black powder-coated steel casing shows only light surface dust and storage marks consistent with careful warehouse storage. The centrifugal impeller is clean and undamaged, with no visible corrosion or impact damage. The flexible inlet ducting is supple and intact, and the outlet damper assembly operates smoothly. The control panel features a functioning hours meter reading just 4 hours, an analogue pressure gauge calibrated in Pascals, and a rotary speed control dial. All electrical connections are intact with grey power leads properly secured. The unit was last performance tested on 30 April 2021 with certified airflow of 5093.5 m3/hr, well within specification.
Centrifugal fans of this capacity are in steady demand across Australia for workshop dust extraction, spray booth ventilation, and industrial air handling applications. Comparable units in this power range typically sell between AUD 2,800 and 4,200 depending on condition and hours. This example, with factory test certification, minimal hours, and excellent mechanical condition, represents strong value for buyers seeking reliable air movement equipment.
Condition
The exterior casing is clean with only minor cosmetic marks from storage. The impeller housing shows no damage or deformation. All fasteners are present and secure.
