Suttner ST-1500 Pressure Spray Gun

The Suttner ST-1500 Pressure Spray Gun is a heavy‑duty, industrial spray gun built for demanding cleaning jobs, rated up to 5000 psi with a flow of about 10.4 gallons per minute. It uses a standard 3/8" FPT inlet and a 1/4" FPT outlet, making it compatible with common high‑pressure hoses and lances. Suttner labels the ST‑1500 as its most popular spray gun, a staple in industrial pressure washing for tasks such as equipment degreasing, concrete cleaning, and routine maintenance. For environments with harsher chemicals, the lineup includes variants like ST‑1500 Stainless Steel Spray Gun, which adds stainless construction (approximately 1.24 lb in the stainless version), and ST‑1500C, the chemical‑resistant model. These options preserve the same core performance while offering material choices to suit durability needs in challenging settings. Whether used in shops or on job sites, the ST‑1500 family is designed for reliable service and straightforward field maintenance, with a wide ecosystem of compatible nozzles and lances that keeps downtime to a minimum.
