Reactor A-25


Air-Driven Foam Proportioner

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

[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]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.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_tta_tabs][vc_tta_section title=”Features” tab_id=”1447219463273-833a6e29-afb8″][vc_column_text]

  • 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
