Filter Bowls/Boxes

SELEE’s precision-engineered filter bowls are unique. Their development and design are based on our own metallurgical engineers’ years of experience in the field of aluminum melt filtration and molten transfer technology. SELEE® utilizes an innovative fused silica material in the designing the filter bowls. The filter bowls can be ordered as Single, Duplex, Triplex, or Staged. They can also be custom-designed to meet our customers’ metal filtration requirements.


• Thermal-shock resistant
• Easy to clean due to design
• Non-wetting for longer life
• Corrosion resistant
• Insulating



SELEE® produces several Preheat Burner and Lid systems to meet any filter preheat requirements. HVB Preheat Burners will provide aluminum cast shops with safe and reliable pre-heating of Filter Bowls and Ceramic Foam Filters. SELEE HVB-AC is the next generation portable preheat burner. Temperature control provides stable reliable operation.
