The BF4000 is a heavy-duty filtration component engineered to protect pneumatic circuits from water, oil aerosols, and solid particles. It features a large-volume collection bowl and a high-efficiency 40μm filter element to maintain optimal system performance. The unit is constructed with a rugged aluminum alloy body and includes a transparent polycarbonate bowl shielded by a specialized metal guard for enhanced safety in industrial environments. Its modular design allows it to be easily combined with other AIRMIXS air treatment products, such as regulators and lubricators, to create a complete FRL assembly.
