1) Reject welding: the complete head made by CNC, more stable!
2) One-Piece Made Head: An electron discharge machine makes the holes to ensure the correct air position at the impeller, and then it can keep the big Torque.
3) Closed Cartridge: Speed increase by 10-15%,30% increase in cutting efficiency! Easy to replace!
4) Impeller: The Impeller is checked by a German dynamic balancing machine. Run more smoothly, lower noise, and longer life.
5) Ceramic Ball Bearing: Ceramic bearing, with shield, from Japan, runs more smoothly, has lower noise, and longer life.
6) Pushbutton shaft: Specially designed needle structure, the key materials are imported, and the key part is sent abroad to do heat treatment.
7) After pressing 30000 times, the holding force is still above 2kg.
8) Dust-proof structure: Cartridge passed the German dynamic balance machine test.
