Ordering Information
Graco Reactor A-20
253831 Bare proportioner for all voltages
and phases
253834 System package. Includes Reactor A-20,
50 ft (15m) heated hose, 10 ft (3m)
heated whip hose and Air Purge Fusion®
gun with AR4242 (01) mix chamber.
Upgrades and Features
Improved Heater Design
Heats material quickly with 6,000 watts of heat –
provides accurate heat control for reliable spraying
in colder environments.
Automatic Hose Heat Control
No transformer taps to change. Automatically
powers up to 310 feet of hose.
Power Conversion
Jumpers provided to easily adapt to different
electrical supply voltages.
Automatic Over-temperature Shutdown
Primary and hose heat circuit shutdown with
resettable switches.
New Solenoid Valve and Larger Air Lines
Increased airflow to air motor improves efficiency
and increases output.
ISO Pump Lube System
Recirculates TSL (Throat Seal Liquid) around the
ISO pump seal. Prevents ISO from forming hard
crystals on the pump rods.
Ready to Spray
Basic unit includes inlet strainers, ball valves, air
filter/water separator, and fluid temperature sensor
for whip hose.
