VDT Domed Perlon Brush
 
The VDT Domed brushes are available in two sizes: 100mm⌀ and 250mm⌀. 
 
The 100mm⌀ brush is perfect for small-scale ducts like flexible w/c extracts or laundry ducts. Its rounded head design also makes it ideal for cleaning grills and the surface of spiral ducts.
 
For larger ducts ranging from 150mm⌀ to 250mm⌀, the 250mm⌀ brush is the go-to option. Its unique design allows for more efficient cleaning in corners and is perfect for turning veins and grills in spaces with limited access.
