When transport via the low pressure system is complete, the -head-air apparatus is installed at the front end to transport the power via the air pressure generated from the device. The above system has the air pressure device at the front end, but it generates pressure after taking in air. Therefore, the filtering device is installed at the front end of the -head-air apparatus to prevent foreign substances from being mixed in. To keep a lower concentration and to supply a regular amount of material to be discharged to a transfer pipe, a supplying device like a Rotary Feeder and an Air Lock Hopper are necessary. The air intake devices most frequently used are ROOTS and the TURBO BLOWER. This is a system suitable for distributing and transporting to multiple areas, with its diverter installed in the middle of the system.
