Bonded Particle Filters
Overview
Pyrotek bonded particle filters (BPF®) are used in aluminium gravity casting (permanent mould), high-pressure die casting, low-pressure die casting and high-performance sand foundries to remove inclusions. The use of BPF has proven to be an effective solution in aluminium foundries for removing oxides from molten aluminium and alloys. The use of these filters has effectively improved casting quality.
Pyrotek Offerings
Pyrotek bonded particle filters contain high-purity silicon carbide aggregate and have excellent strength, durability and chemical resistance for long life. They also have high-thermal conductivity to minimize thermal gradients, greater filtration efficiency through a complex internal structure and are cost effective. All bonded particle filter raw materials, process parameters and product manufacturing lots are subject to rigorous quality control to ensure the highest possible integrity, consistancy and performance.
Bonded particle filters are available in different shapes and grit sizes ranging from 6, 8, 10 and 12. Below are examples of BPF product applications.
- Vertical gate filters
- Box filters
- Pump filters
