Electric silo for 25 kg plaster. The inner rubber lining is sealed to prevent degradation of the gypsum caused by moisture ingress. The opening of the lower diaphragm automatically activates the vibration of the inner lining to ensure a constant flow of gypsum, thus preventing the formation of lumps during dosing. The syloplaster is recommended for wall-mounted installation, but can be equipped with a LIFT-O-PLASTER lifting system to facilitate plaster loading.
