Specifications Grate magnet 1,Material:noedymium-iron-boron. 2,Strength:8000~12000Gs. 3,Diameter:D19mm,D22mm,D25mm,D32mm Grate magnet Good quality and service is the soul of our business. Sincerely look forward to cooperating with you. Description 1.The standerd diameter we supply isD25,ect.The size and length will vary at your request. 2.The magnetic field strength can reach at a surface Gauss Lever(8000Gs~12000Gs). 3.Working tempreture:80°C~350°C Function You can only design standard thread on top ends to hold rods on a simple frame. Any liquid contaminated with rust, swarf or other metals attracted to magnet rod, it will benefit from passing through the powerful simple filter (magnetic grid). The filter can get rid off the oxide particles, particles and impurity in liquid because of the magnetic flux, Thereby, increase water flow, reduce the power consumption and maintenance cost. Protect against the damage of equipment, prolong the life of equipment.
