Application Operation principle Advantages Highlights Comparison To feed plastics processing machines with virgin, regrind or additives materials from any source in a stand alone application. Conveying small quantity of material : Max 50Kg/h for distance up to 5mt Max 20Kg/h for distance up to 10mt Where available space is: Height no more than 433 mm (522 mm to open the lid) Width no more than 278 mm (449 mm with open lid) Where the mounting plate/lid is no bigger that 205 mm Where a light weight is required: machine total weight is 9 Kg Where just a single phase line with 1000 W is available

Application Operation principle Advantages Highlights Comparison The magnetic level sensor detects the flap in a closed position and activate the feeding cycle At the beginning the filter is cleaned through a blast of compressed air to increase the suction efficiency and to clean the flap from possible material sitting on it Blower is activated and material is conveyed for the preset time At the end of the time a new filter cleaning is performed to help material fall out and keep filter clean Machine is in idle condition waiting for a new signal of start from magnetic level sensor

Application Operation principle Advantages Highlights Comparison Benefit: Body: Entirely made out of stainless steel (AISI 304) Body: Not subject to wear Body: No contamination by abrasion Blower: Twice blower life thanks to the soft start function Blower: Three alarm levels warn the status of wear of the motor brushes. The third stops the motor before any damage occurs Lid: Hinged to body for easy opening and access to the filter Mounting flange, made of cast aluminum, allows 360° rotation for high flexible positioning Integrated differential pressure switch to constantly check the filter status and alarming in case of clogging ensuring longer blower life Really compact design Automatic filter cleaning to allow reduction of frequency for manual filter cleaning Inspection door for easy maintenance and access to the discharge flap Pre-set parameters for ready to operate machine the moment power is connected (machine RUNS with no keypad!) and adjustable suction time Easy maintenance Performance: Body: Specific design that allows uniform descent Body: No jamming of granules Body: Plasma welding in inert gas for accurate finishing Blower: Integrated giving compact design and independent function Blower: Low noise level blower available (less than 80 dB) Lid: Clamp guarantee easy opening and sealing of closure Discharge flap with gasket to improve vacuum sealing Function and alarm are signaled by green and red LED’s present at the base of the control box Reinforced paper filter (10 µm) with nylon protection EC conformity certificate Keypad allows to set-ups: Loading time Idle time (for manage accumulation of regrind) Proportional valve percentage Number of failed loads before alarm Filter cleaning function

Application Operation principle Advantages Highlights Comparison VP valve is available as special application as the loader use to have 30 mm diameter inlet. S40 utilizes special flexible hose and suction probe 30 mm diameter. Filter cleaning device must be installed in Piovan it can not be fit After Sales. Keypad can be equipped with RS 485 serial communication port and acoustic alarm all in one OPTIONAL (see Operation page). Keypad is removable up to 5mt. Acoustic alarm with adjustable tone available. Available adapting flanges from 185 mm to 210mm and 280mm. Loader can be directly flanged on the injection-moulding machine using a maintenance hopper (see beside picture).
