Description

The Graco Reactor E-10 Proportioner brings serious performance in a compact package. The E-10 plugs into standard 120 V or 240 V outlets (depending on model) so you can bring serious plural-component spraying—foam, coatings or polyurea—to hard-to-reach zones without a full rig. With a maximum working pressure of 2,000 psi (13.8 MPa) and a flow rate of up to 12 lb/min (5.4 kg/min), the E-10 keeps pace with demanding spray tasks. Its intuitive single-knob control and digital temperature display streamline startup, while pressure-balance valves reduce fluctuations and maintain a consistent pattern. Built with serviceability in mind, the fluid section is easy to access, and the unit uses a 7-gal (26.5 L) on-board tank set for quick mobilization. Whether as a standalone for smaller projects or an add-on to an existing spray business, the Reactor E-10 delivers big-machine capability in a job-site friendly form, including polyurea.

Frequently Asked Questions

Service & Support

How quickly does the Graco Reactor E-10 reach operating temperature for hot-spray foam applications?

The manual indicates the E-10 features two recirculation speeds (slow/fast) to heat hoses and fluid faster, which helps get the system ready quickly even for touch-ups or moderate flows.

If I switch from 120 V to 240 V model, what changes should I expect in performance or power draw on the Reactor E-10?

The 240 V version has a lower amp draw (e.g., 2-cord 10 A circuits) and still offers up to 12 lb/min output, meaning you maintain flow but with different electrical requirements.

Can the Reactor E-10 handle longer hose runs without noticeable pressure drop or pattern degradation?

The spec sheet indicates maximum hose lengths up to ~310 ft and balanced proportioning using pressure-balance valves.
