New counter nut for backwashing

The new counter nut MUL60 has been specially developed for the use in filter systems with backwash. In combination with the tailpipe of the nozzle, the specifications of the nut support the build-up and even spreading of the air cushion below the filter floor during the backwash. Even when using little air, an even air distribution is thus assured. 

You can recognise our new nut MUL60 by its reduced drain slots. Otherwise, the design and application are similar to our established counter nut MU60.
