The PFT system for the construction site includes a wide range of accessories. This also includes bag squeezers. With the help of the mechanically operated device, paste-like material can be completely emptied from the bag. PFT bag squeezers are usually mounted on the material hopper and are available for various versions of the PFT delivery pumps RITMO and SAMBA. A bag squeezer on a pedestal is available for the SAMBA XL.
