Enviromax Room Ventilation
Remove steam, moisture, stale air and unwanted odours from bathrooms, laundries and enclosed rooms with a powered Enviromax ventilation system.
Choose the Right Enviromax System
Ducted Room Ventilation
Extracts steam, moisture and odours, discharging them outdoors.
Single-cap Roof ventilator
Compact powered extraction designed to remove hot, humid air from the roof cavity.
Double-cap Roof ventilator
Higher-capacity powered extraction for larger or more demanding roof cavities.
Moist air out. A fresher room below.
The ducted Enviromax configuration carries air from the internal room through the roof and releases it outdoors – not into the roof cavity.
Why vent directly through the roof?
More effective extraction
A dedicated vertical duct path efficiently carries steam, stale air and odours out of the home.
Helps reduce moisture build-up
Moist air is discharged outdoors before it can settle in the ducting or roof cavity and contribute to mould growth.
Quieter where it matters
The motor is mounted at roof level, further away from the room below for quieter in-room operation.

Room ventilation FAQs
What is the Enviromax Room Ventilation System, and how does it work?
The Enviromax Room Ventilation System is a powered, roof-mounted extraction system designed to remove warm, humid and stale air from moisture-prone rooms such as bathrooms and laundries.
Air is drawn from the room through an internal ceiling vent and ducted outside through the roof-mounted ventilator. Unlike a wind-driven roof vent, Enviromax uses a 240V motor, so it can provide reliable ventilation even when there is little or no wind. By removing steam, moisture and odours at their source, it helps reduce condensation, discourage mould growth and keep the room fresher and more comfortable.
Depending on the selected model, the system can be operated using a switch or thermostat control.
Can Enviromax ventilate a bathroom without windows?
Yes. Enviromax is an effective ventilation solution for bathrooms without windows or where windows cannot be opened for security or privacy reasons.
The system draws steam, humid air and odours from the bathroom and expels them outside through the roof-mounted ventilator. This helps the room dry faster while reducing condensation and the conditions that encourage mould and mildew.
For effective extraction, the bathroom must also have a source of replacement air, such as a suitable gap beneath the door or a transfer grille. A Solatube dealer can assess the room and recommend the appropriate installation.
Does Enviromax discharge bathroom air outside or into the roof cavity?
Enviromax is designed to discharge moisture-laden bathroom air outside the home, not into the roof cavity.
Air is drawn from the bathroom through an internal ceiling vent and ducted directly to the roof-mounted Enviromax ventilator, which expels it outdoors. This helps prevent steam and moisture from accumulating in the roof space, where they may contribute to condensation, mould, saturated insulation or damage to building materials.
For applicable building work, current NCC-related compliance guidance requires bathroom exhaust air to be discharged outdoors and does not permit exhaust ducting to terminate within the roof space. However, requirements can vary according to the building, location and scope of work. The installation should therefore be assessed and completed in accordance with applicable state, territory and local requirements.
How does Enviromax airflow compare with NCC requirements and a standard bathroom exhaust fan?
The Solatube Enviromax Ducted Room Ventilation System delivers 324 m³/h (90 L/s)—around 3.6 times the NCC minimum airflow rate and more than many standard bathroom exhaust fans. Its roof-mounted motor draws moisture-laden air through the ceiling grille and ducts it directly outdoors, providing powerful extraction with reduced motor noise inside the room.
Can room ventilation help reduce mould and condensation?
Yes. Effective room ventilation removes moisture-laden air before it can settle on walls, ceilings and other surfaces. This helps reduce condensation and the damp conditions that encourage mould growth, particularly in bathrooms, laundries and other enclosed spaces.
Is Enviromax quieter than a ceiling-mounted exhaust fan?
Enviromax is designed for quieter in-room operation because the motor is mounted at roof level, away from the occupied room. Actual noise levels will depend on the system configuration, ducting and installation.
Can Enviromax ventilate laundries, kitchens and walk-in wardrobes as well as bathrooms?
Yes. Enviromax can provide room ventilation for moisture-prone or poorly ventilated spaces, including laundries, kitchens, walk-in wardrobes and bathrooms.
In laundries, it can help remove heat and humidity produced by washing machines and dryers. In walk-in wardrobes, improved airflow can reduce musty odours and the moisture conditions that encourage mould and mildew. In kitchens, Enviromax can assist with general heat, humidity and lingering odours; however, it is not a substitute for a compliant rangehood designed to capture cooking grease, smoke and fumes at their source.
The most suitable system configuration will depend on the room’s size, moisture levels, available replacement air and installation layout. A Solatube dealer can assess the space and recommend the appropriate Enviromax solution.
What is the difference between the single-cap and double-cap Enviromax systems?
The main difference between the single-cap and double-cap Enviromax systems is their extraction capacity and control options.
The powered single-cap system provides an airflow rating of up to 520 m³/hr and is available with optional thermostat control. It may suit smaller rooms or applications with lower ventilation requirements.
The powered double-cap system provides an airflow rating of up to 820 m³/hr—approximately 58% more airflow than the single-cap model. It includes thermostat control, allowing the system to switch on and off automatically according to the selected temperature setting. Its higher capacity may make it more suitable for larger spaces, multiple extraction points or areas with greater heat and moisture loads.
Both powered systems operate independently of wind. The correct model depends on the room volume, number of extraction points, ducting layout and required airflow, so a Solatube dealer should assess the property before recommending a system.
