CSR Windmaster Mill 300mm

The CSR Windmaster Mill 300mm is the unpainted version of the Windmaster wind driven roof ventilator. It uses the same 300mm turbine design to extract hot, moist air from the roof space, but the mill finish leaves the metal bare, which suits commercial and industrial roofs where a painted turbine is not needed. It is a straightforward, energy-free way to keep a large roof cavity ventilated.

Key Features

• 300mm diameter wind driven ventilator
• Mill finish, unpainted metal for commercial and industrial roofs
• Operates on wind power, no electricity required
• Extracts hot, moist air to reduce heat build-up and condensation
• Corrosion-resistant steel construction
• Low maintenance with no moving electrical parts

Specifications

• Product: CSR Windmaster Mill
• Diameter: 300mm
• Finish: mill (unpainted metal)
• Weight: 3.10 kg
• Dimensions: 47.5 x 52.0 x 46.0 cm (boxed)
• Application: roof space ventilation, commercial and industrial

How It Works

The turbine head spins in the wind and draws hot, moist air out of the roof cavity, which keeps the roof space cooler and drier. The mill finish is left unpainted so the unit costs less and blends into commercial roofs, where the metal body of the vent does not need to match a colour scheme. It is the same reliable wind-driven design as the Colorbond version, without the paint.

Applications

• Sheds, warehouses and industrial roof spaces
• Commercial buildings where a painted vent is not required
• Reducing heat build-up and condensation in large roof cavities
• Energy-free ventilation for workshops and farm buildings

What You Need To Complete The Job

For a colour-matched unit on a residential roof, see the Windmaster Colourbond 300mm. Where the unit connects to a duct run, use flexible foil ducting. Browse the Roof Ventilation range for the full selection.

Frequently Asked Questions

What is a mill finish ventilator?

It is a wind driven turbine left unpainted, with the bare metal body. The mill finish keeps the unit more economical and suits roofs where matching a colour is not important, such as sheds and industrial buildings.

How is it different from the Colourbond Windmaster?

Both are 300mm wind driven ventilators with the same turbine action. The Colourbond version has a painted finish in roof-matching colours, while the Mill version is unpainted and aimed at commercial and industrial roofs.

Does it need power?

No. It is powered by the wind. The head spins and draws air out of the roof space, so there is no electricity, no wiring and no running cost.

What size roof space does it suit?

The 300mm diameter suits medium to large roof cavities, which is why it is common on sheds and commercial buildings. For a residential roof, the Colorbond version matches the roof finish.

Does the mill finish need painting?

No. The mill finish is supplied unpainted and is designed to be used as-is on commercial and industrial roofs. It is a bare metal surface, so it does not match a roof colour, which is exactly why it is aimed at roofs where a painted vent is not required.

Where does the mill finish suit best?

The mill finish suits roofs where a painted unit is not needed, such as sheds, workshops and industrial buildings. It keeps the cost down and blends into the bare metal of a commercial roof line, while the wind driven turbine still does the same ventilation job.
