Q MAX AC 250MM 0.9A – 1590m3/hr – 3 Speed

Description

Q Max AC 250mm 0.9A — 1590m³/hr 3-Speed is a high-output, three-speed axial duct fan designed for large-volume air movement in commercial grow rooms, industrial ventilation applications, and any space requiring high-capacity airflow management. We have been supplying professional-grade ventilation equipment to UK growers since 2017, and the Q Max AC range addresses the extraction requirements of large-scale indoor cultivation environments where standard inline centrifugal fans cannot deliver sufficient airflow.

High-Volume Airflow for Large Commercial Growing Environments

The 1590m³/hr maximum airflow of the Q Max AC 250mm represents a significant step up from standard grow room inline fans, making it appropriate for grow rooms of 50m³ or more where air exchange targets of 30–60 times per hour demand very high fan capacity. At 250mm duct diameter and three fixed speed settings, this fan provides the flexibility to match airflow to seasonal demands — higher speeds during summer when cooling is a greater priority, lower speeds during winter when temperature management requires less extraction.

The axial design is optimised for high-volume, lower-static-pressure applications compared to the centrifugal inline fans used in standard grow rooms. This makes it most effective in short ducting runs with minimal bends and obstacles — ideal for grow rooms with direct wall penetrations or short exhaust paths rather than complex multi-bend extraction routes where centrifugal fans maintain better performance against back pressure.

Installation and Electrical Requirements

At 0.9A current draw, this fan operates comfortably on standard UK electrical circuits. Mount securely in your ducting run or wall penetration point. The three fixed speed settings are selected at the fan body — for variable speed control over a continuous range, specify a fan with EC motor or use with an appropriate external speed controller if one is compatible with the motor type.

Pairs with large-diameter insulated ducting, commercial-scale carbon filters and appropriate ducting connectors for a complete large-scale extraction system.
