All-Purpose Equipment Drive Unit AR 403

The ERWEKA All-Purpose Equipment (APE) System is a modular, multi-functional solution designed for a wide range of R&D and small-scale production tasks across the pharmaceutical, chemical, cosmetic, and food industries. At the heart of the system is the AR 403 drive unit, a robust and high-precision motor base that powers an extensive selection of interchangeable attachments for mixing, milling, granulating, coating, blending, and more.

⚙️ AR 403 – High-Performance Universal Drive Unit

The AR 403 is equipped with a three-phase AC motor, delivering reliable torque and exceptional durability. Its maintenance-free worm gear provides up to 23 Nm output torque, ensuring stable operation even under heavy loads.

A digital speed control allows smooth adjustment between 20–400 rpm, while the built-in electronic regulation continuously balances nominal/actual values — maintaining constant speed regardless of load fluctuations.

The AR 403-S variant features an enhanced drive train tailored for particularly intensive applications.
