Circular Duct Elbows | Grow Room Ventilation Bends 100–315 mm

Circular duct elbows provide a change of direction in a compatible round ventilation run without needing to bend or crush a straight connector. They help route extracted air around corners, through grow room layouts and towards suitable external exhaust points.

Six nominal diameters

• 100 mm (4 in): one circular duct elbow for a compatible 100 mm ventilation connection.
• 125 mm (5 in): one circular duct elbow for a compatible 125 mm ventilation connection.
• 150 mm (6 in): one circular duct elbow for a compatible 150 mm ventilation connection.
• 200 mm (8 in): one circular duct elbow for a compatible 200 mm ventilation connection.
• 250 mm (10 in): one circular duct elbow for a compatible 250 mm ventilation connection.
• 315 mm (12 in): one circular duct elbow for a compatible 315 mm ventilation connection.

Choosing an elbow

Match the nominal diameter to the fan outlet, carbon-filter spigot or installed ducting. Plan the route to avoid unnecessary turns; each change of direction can add resistance and should be allowed for when specifying the extraction fan. Secure and seal connections with suitable duct clips or other compatible fixings.
