Description

Prevost ATU Series Air Filter (ALTO)

The First Line of Defense for Your Pneumatic System

Safeguard your air tools and machinery from the leading causes of failure with the Prevost ATU Series Air Filter. As the foundational component of the ALTO air preparation system, this high-efficiency filter effectively traps moisture, dust, pipe scale, and other airborne contaminants before they can damage your valuable equipment.

Utilizing powerful centrifugal force, the ATU filter spins incoming air to separate heavier liquid and solid particles, while a high-quality filter element captures the remaining fine debris. The result is clean, dry air that prevents corrosion, reduces maintenance downtime, and ensures your pneumatic tools run smoother and last longer.

Key Features & Benefits

  • Superior Contaminant Removal: Effectively removes solid particles (standard 25µm) and bulk liquids, preventing them from entering your valves, cylinders, and motors.
  • Cyclonic Separation: The internal baffle design spins the airflow, forcing water droplets and heavy debris to the bottom of the bowl for easy drainage.
  • High Visibility Bowl: Available with a clear polycarbonate bowl (often with a protective guard) or sight glass, allowing you to instantly check the condensate level and filter condition.
  • Modular Connectivity: Designed to clamp seamlessly with Prevost Regulators and Lubricators using the ALTO joining kits, creating a clean, professional FRL assembly.
  • Easy Maintenance: The filter element is washable or easily replaceable, and the bowl features a quick-release mechanism for hassle-free cleaning.

Ideal Applications

  • General Workshop Air: The essential primary filter for any air drop servicing impact wrenches, drills, and grinders.
  • Machine Protection: Pre-filtering air for packaging machines and assembly robots to prevent valve sticking.
  • Paint Prep (Stage 1): Removing bulk water and dirt before air passes to finer coalescing filters for spray painting.
  • Tire Inflation: Ensuring only clean air enters tires to prevent rim oxidation and valve stem clogging.

Maintenance Tip: Check the water level in the bowl daily. If you have a Manual Drain model, open the valve at the bottom to release the water. If you have a Semi-Auto drain, it will automatically drain when the pressure is removed (or can be pushed manually).
