Centri-Flo Separators

The Centri-Flo Separator incorporates four methods of moisture separation for maximum efficiency. The cyclone, centrifuge, baffles and boundary-layer control features offer many advantages to moisture separation. Tests show Pioneer separators to be more efficient and more reliable over a wider flow range than competitive models.

How It Works

Compressed air, gas or steam enters the separator at a high velocity. The specially designed centrifuge element provides the primary separation. The bell reducer also forces compressed air to rub and impact against baffles to further improve the separation efficiency. These baffles are strategically located and placed at a specific angle for optimum separation. The specially designed convex drain plate prevents accumulation of condensate at the compressed air re-entry point into the bell reducer. The large opening of the bell reducer keeps air velocity low thus preventing moisture re-entrainment.

Together the four-step moisture separation and the prevention of moisture re-entrainment provide the maximum moisture separation efficiency.
