The QBY-25 hits a sweet spot for many users. With a 25 mm port and flow up to 2.4 m³/h, it’s big enough for production work but small enough to move around. I’ve seen these used everywhere from small workshops to large factories.
Why It Works Well • Self-priming up to 7 meters • Handles solids up to 2.5 mm • Runs on shop air — no electrical connection • Lightweight and portable • Easy to clean between batches
