The AFR2000-G1/4'' combines the functions of a high-efficiency air filter and a high-precision pressure regulator into one modular body. It effectively removes water droplets, oil aerosols, and solid particles from the compressed air stream using a centrifugal separation method, while the integrated regulator allows for fine-tuned output pressure adjustment via a non-rising, locking adjustment knob. The unit features a robust aluminum alloy body for industrial durability and a transparent polycarbonate bowl for quick visual inspection of collected contaminants. Equipped with a built-in pressure gauge and a rapid-drain valve, the AFR2000 is engineered for easy installation and low-maintenance operation in manufacturing, automotive, and automation environments.
