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

2. 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

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
