The ProFill range consists of 2 refill products for commercial systems of different sizes. These products are not permanently fitted to the system. They are used to fill the system and then removed. To top up the water in the system (refill/top up), you should use one of the permanently installed filling products (SpiroPure Home / Pro). There are two sizes for the SpiroPure ProFill (Mobile Filling) (9.5 and 23.0 liter tank).
