The Graco Reactor A-25 Proportioner (SKU# 262572) delivers a reliable, entry-level solution for spray foam professionals who want consistent performance without unnecessary complexity. Designed for residential and light commercial use, this air-powered system offers impressive output and straightforward operation.
With the ability to spray up to 25 lb/min, the A-25 works exceptionally well for small jobs, quick repairs, and mobile applications. Because of its compact design and robust construction, this unit makes a smart choice for contractors who value durability and ease of use.
Enjoy Consistent Heating and Spray Control
Thanks to three independent heat zones—one each for ISO, resin, and hose—you can maintain precise material temperatures. As a result, you’ll experience improved foam yield and better overall spray quality. This feature allows you to adapt quickly to changing job site conditions and helps reduce wasted material.
Track and Balance with Built-In Tools
The A-25 includes Graco’s DataTrak system, which provides real-time tracking of material usage and pump cycles. This makes it easier to monitor spray rates and manage job costs.
Additionally, the integrated recirculation manifold balances pressure before you begin spraying. Not only does this reduce prep time, but it also supports a smoother startup process. These built-in systems streamline daily operations while giving you better control over your material flow.
Simplify Maintenance with Durable Design
Graco built the A-25 for quick and easy maintenance. You can remove the quick knockdown lower pumps without disassembling the entire machine, saving time on cleaning and repairs. In addition, the ISO lube system prevents isocyanate from building up on the shaft and seals.
These smart design elements minimize downtime, which means you can complete jobs faster and reduce service interruptions.
Fit for Residential and Mobile Applications
Whether you’re working in an attic, a crawl space, or a small commercial structure, the A-25 adapts well to tight spaces. It works particularly well for:
- Residential insulation projects
- Spray foam repairs and touch-ups
- Contractors entering the spray foam market
- Rigs that need a compact secondary unit
Because it supports hose lengths up to 210 feet and delivers consistent pressure up to 2000 psi, you can reach farther while maintaining excellent spray performance.
