Graco GH™ 300 ProContractor Series — Gas Hydraulic Airless Sprayer

The GH 300 ProContractor Series is Graco's elite hydraulic sprayer designed for high-production contractors who demand maximum power on the largest commercial jobsites. Engineered to handle a vast range of heavy materials—including latex, elastomerics, block fillers, and protective coatings—this unit combines the unstoppable force of hydraulic drive with advanced productivity features. As part of the ProContractor Series, it is built to eliminate jobsite downtime and increase profitability through superior hose management and rapid pump maintenance systems.

ProContractor Series Advanced Features

QuikReel™ Hose Management System: Deploy and rewind up to 90 metres (300 feet) of hose in seconds. This integrated reel prevents twisting, kinking, and coiling, allowing you to use only the length required while the rest stays safely on the unit.
ProConnect™ Pump Replacement: Switch out your pump lower in 1 minute or less without tools, pins, or extra parts to lose. This ensures you stay productive even if a pump requires service mid-job.
Endurance™ MaxLife™ Piston Pump: Lasts 6X longer between repacks due to innovative MaxLife technology. Oversized fluid passages minimize pressure drops to maintain high-velocity flow with the thickest materials.
Crushproof Inlet Strainer: An ultra-durable filtration system designed to withstand harsh impacts on-site while maintaining a consistent, even flow of material to the pump.

Key Performance Features

High-Efficiency Hydraulic Motor: Delivers rock-solid performance with a faster, more responsive changeover and fewer moving parts for reduced maintenance.
High-Capacity Cooling System: Innovative reservoir design with cooling fins deflects heat away from the sprayer, allowing the pump to run cooler and more efficiently during all-day operation.
Honda® GX Engine: Reliable, contractor-preferred power featuring Oil Alert™ to automatically shut down the engine if oil levels drop too low.
Rugged Steel Cart: Built with thick chrome over welded steel to survive the most punishing environments, featuring pneumatic wheels for vibration absorption.

FAQ

What is the number one rule when using airless spray guns?

The number one rule when using airless spray guns is: Never point the spray gun at yourself or anyone else, and never place any part of your body in front of the spray tip. This is due to the fact that airless spray guns use very high pressures—high enough to push paint or other fluids directly under your skin, which may cause severe injury or need emergency treatment. This is injection injury, which is dangerous even if it appears to be just a tiny puncture. Always follow proper safety procedures: Use protective gear (gloves, goggles, coveralls). Keep the spray gun trigger locked when not spraying. Relieve pressure in the system before cleaning or servicing. Safety first, always.

What to know about airless paint sprayers?

Airless paint sprayers use high pressure to spray paint without air, giving fast, smooth coverage—great for large surfaces. Always wear safety gear, never point the gun at yourself, and make sure to depressurize and maintain the sprayer properly after each use.

Do you have to clean Graco sprayer between coats?

If you're working with the same color of paint and taking a quick break, you don’t need to clean it thoroughly—simply cover the tip and maintain the primed condition. On a longer break (several hours), flush the sprayer or at least the tip and nozzle to prevent clogging.

Is Graco a good airless paint sprayer?

Graco is a top brand most commonly known for its airless paint sprayers. Graco sprayers are long-lasting and a high-quality performer, although they do need occasional servicing to remove clogs. In general, Graco has a variety of airless sprayers that produce professional-grade finishes for a wide range of painting projects.
