Ventilation

Cyclones for the roof, louvres for the walls

Two ways to move air

Choose the right ventilation option

Muwi ventilation keeps factories, godowns, kitchens and farms cool without electricity. Cyclone turbines sit on the roof and spin in the lightest wind to pull hot air, fumes and humidity out through the ridge. FRP louvres sit in the walls and let fresh air in through corrosion-proof blades with an insect screen. Most industrial buildings use both: louvres low in the walls for intake and cyclones high on the roof for extraction.

High-capacity ventilation that works without electricity

Cyclone Fan SS304-700 (Industrial Pro)

A 700 mm heavy-gauge stainless steel wind-driven turbine on NSK sealed bearings, with a leak-proof FRP base matched to S-ACT profiles.

Choose this whenExtracting heat, steam, fumes or humidity from large roofs: godowns, manufacturing plants, food processing, kitchens, poultry houses. Fits S-ACT roofs with a leak-proof FRP base or flat roofs with a stainless base.

Models: S304 (600 mm) · S201 (600 mm, 500 mm, 400 mm, 300 mm)

Heavy-gauge SS304 turbine
Genuine NSK dual-sealed bearings, lubricated for life
Starts in winds under 2 km/h
Leak-proof FRP base for S-ACT roofs

Corrosion-proof ventilation louvers with insect screen

FRP Louvers

Glass-fibre reinforced plastic louvers that weigh a quarter of steel, never rust and last 20 to 30+ years with virtually no maintenance.

Choose this whenWall ventilation and air intake, especially in coastal, chemical, electroplating or wastewater sites where steel and aluminium louvres rust. Supplied with an insect screen.

About 75% lighter than mild steel, 30% lighter than aluminium
Strength-to-weight ratio 4 to 5 times that of steel
Non-rusting, non-corroding, non-conductive
20 to 30+ year outdoor service life, virtually maintenance free
