GRACO 24G621 - Agitator Speed Controller- Automatic Speed Controller for Air Drive Agitators, 100 PSI

GRACO 24G621 Agitator Speed Controller provides closed-loop speed control for air-driven agitators, maintaining constant set speed even as viscosity or drum levels change. This automatic control system prevents over-agitation of shear sensitive materials, extends agitator lifetime by eliminating overspeeding, and reduces energy costs by optimizing air consumption.

Specifications

• Max Working Pressure: 7 bar (0.7 MPa, 100 PSI) maximum air input pressure
• Maximum Speed: 1000 rpm
• Speed Control Range: 100-1000 rpm
• Weight: 0.64 kg (1.4 lb)
• Installation Time: installs within minutes

Features

• Controls and maintains agitator speed
• Speed regulation independent of drum level
• Speed regulation independent of viscosity changes
• Works with air drive agitators
