For thorough ventilation of core boxes and moulding plates.
More than 40 % of the filter surface is open, i.e. air-permeable. Compared with conventional slit type core box vents (about 13 % aperture ratio), you are able to use fewer and smaller vents.
A unique, proprietary fusion technology makes the “Super Vent” really long-lasting. Thus the head plate remains intact even after extended use.
To prevent rust and achieve easy mold release, a surface treatment is applied.
The wave type “Super Vent” uses a wave-shaped, self-cleaning structure. The other types also use thin head plates, resulting in a structure to which sand does not easily adhere.
Ideal also for gassing in Cold Box procedure.
