🌬 Isomax Acoustic Fan Guide & Product Information

🌱 Professional Quiet Ventilation for Grow Rooms

The Isomax Acoustic Fan range is designed for growers who require powerful extraction performance while maintaining extremely low operational noise levels. Built using high-performance RVK mixed-flow fan technology and housed inside insulated acoustic steel casings, Isomax fans are widely regarded as one of the most effective quiet ventilation systems available for indoor grow rooms and hydroponic environments.

Proper extraction is essential for controlling grow room temperatures, humidity levels, stale air, and odours. The Isomax range delivers strong airflow capable of handling larger grow environments, carbon filters, and longer ducting systems while significantly reducing airflow and motor noise compared to standard inline extractor fans.

The insulated acoustic housing absorbs vibration and airflow sound, helping create quieter and more discreet grow room ventilation systems without sacrificing airflow performance.

• ✔ High-powered acoustic grow room extraction
• ✔ Significantly reduced operational noise
• ✔ Excellent airflow performance with carbon filters
• ✔ Ideal for larger grow rooms and extraction systems

🌀 Built Using RVK Mixed-Flow Fan Technology

The Isomax Acoustic Fan range is built around powerful RVK mixed-flow inline fan technology designed to maintain strong airflow performance even when connected to carbon filters, silencers, and longer duct runs.

Unlike basic axial fans, mixed-flow systems generate significantly higher static pressure, allowing the Isomax range to maintain effective airflow where resistance from filters and ducting would reduce the performance of weaker extractor fans.

This makes Isomax fans particularly suitable for professional grow room extraction systems and high-powered lighting setups.

• ✔ Powerful RVK mixed-flow airflow system
• ✔ Strong static pressure performance
• ✔ Ideal for carbon filter extraction systems
• ✔ Reliable long-term ventilation performance

🔇 Acoustic Foam Insulated Steel Housing

The Isomax range features insulated steel housings lined internally with acoustic foam insulation designed to absorb sound generated by both the fan motor and moving airflow.

This dramatically reduces operational noise levels while helping soften airflow sound travelling through the ventilation system. The insulated housing also helps reduce vibration transfer into ceilings, walls, and ducting systems.

The result is a quieter grow room environment without compromising extraction power.

• ✔ Acoustic foam insulated steel casing
• ✔ Reduced airflow and motor noise
• ✔ Reduced vibration transfer
• ✔ Ideal for quieter grow room extraction systems

📏 Available Sizes, Dimensions & Airflow Configurations

The Isomax Acoustic Fan range available from Acorn Horticulture includes multiple 10″ and 12″ configurations designed for medium-large and large grow room extraction systems.

• ✔ 10″ / 250mm – 1480 m³/h airflow
• ✔ 10″ / 250–280mm – 2310 m³/h airflow
• ✔ 12″ / 315/280mm – 2380 m³/h airflow
• ✔ 12″ / 315/315mm – 3260 m³/h airflow

The 10″ models are ideal for larger grow tents and medium-large grow rooms, while the high-output 12″ versions are designed for larger commercial-style grow environments requiring maximum extraction power.

The larger airflow models are especially effective for grow rooms using multiple HID or LED grow lights where heat management and airflow become critical.

⚡ Compatible With Fan Speed Controllers

The Isomax Acoustic Fan range is compatible with fan speed controllers, allowing growers to fine-tune airflow performance and noise levels depending on environmental conditions.

Using speed controllers allows growers to:

• ✔ Reduce airflow noise when full extraction is unnecessary
• ✔ Increase extraction during hotter conditions
• ✔ Maintain stable grow room temperatures and humidity

🌬 Benefits for Indoor Growing

A high-quality extraction system is one of the most important components of any indoor grow room. The Isomax Acoustic Fan helps maintain stable environmental conditions by removing excess heat, humidity, and stale air while improving fresh airflow and carbon filter efficiency.

Proper extraction helps:

• ✔ Control grow room temperatures
• ✔ Reduce humidity and condensation
• ✔ Improve fresh air and CO₂ exchange
• ✔ Improve carbon filter odour control
• ✔ Support healthier plant growth

🔧 Installation Guide

The Isomax Acoustic Fan range is designed for straightforward installation into professional grow room extraction systems.

• ✔ Connect directly to matching carbon filters and ducting
• ✔ Compatible with acoustic and combi ducting
• ✔ Secure using quick release clamps
• ✔ Suitable for suspended installation

For maximum performance, pair with carbon filters, acoustic ducting, quick release clamps, and fan speed controllers.
