D1724 – Coating spindle

The D1724 is a compact turbine-driven rotary atomizer with a maximum speed of 70,000rpm and capable of driving bell cups of up to 70mm diameter. Due to its very compact size, it is ideally suited for use in robotic arm spray booth applications and can incorporate electrostatic internally or externally charged bell cup systems. The shaft nose is suitable for external or internal taper bell cups. Designed for automotive coating applications, the spindle is fitted with a high-efficiency turbine, shaft grounding brushes, integrated shaping air ports and provision for an optical speed sensor system.
