Reactor A-25

Air-Driven Foam Proportioner

For spraying foam insulation - applies up to 25 lb (11.4 kg) per minute

The Reactor A-25 is a Graco-engineered spray foam proportioner that gives you the reliability you expect on the jobsite. It maintains consistent temperature control, even when you're spraying at maximum flow rates - resulting in better quality foam.
  • Maintains temperature setpoints for better yield
  • Maintains consistent output pressure for uniform spray pattern
  • Easy to operate and maintain
  • Best choice for affordability and durability
