From the Manufacturer
The Industrial Construction line has been expressly built to handle the aggressive chemicals and rugged field conditions of the construction industry. All units feature specially formulated high-grade Viton seals throughout. Our Acid sprayers effectively apply acid-based etching and cleaning materials. The Construction line is recommended for building and construction, industrial/ janitorial applications and industrial cleaning. These hand-held units feature specially formulated high-grade Viton� seals throughout. They are built to handle the aggressive chemicals and rugged field conditions of the construction industry. The 12\" internal pump chamber builds up pressure faster with fewer strokes. The high density polyethylene tank with UV inhibitors is more durable than steel. An industrial spray piston with on/off lock lets the user release the trigger while spraying. Seals and O-rings are made of high grade NBR. The hose drains from the bottom of the tank eliminating the need for a siphon tube and allowing the tank to be emptied completely. The unit also features an extra long heavy gauge 20\" brass wand and an extra long 65\" chemical hose rated at 300 psi. A steel spring prevents kinking. There is a convenient wand storage clip on the handle and the wide 4.5\" funnel opening makes for easy filling.
