These kits can be used for any brands of ducted vacuum power units (machines), whether it is AstroVac, AussieVac, Valet, Premier Clean, DAS, Hills, etc., they all use the same size pipe and fittings. We prepare the kits to suit a small, medium or large home. To choose the right kit, roughly devide the size of your home by 8 (1-point kit covers about 8 square area). For example, you will need 2-point kit for a 15-square home (as 15/8 = 2, approximately). Extra pipe and fittings can be purchased separately.
