GJ A2 Tank Cleaning

Application

Designed to fit through a 2” (5.08 cm) sanitary fitting, the Alfa Laval GJ A2 is part of the world-renowned Gamajet range of high impact tank cleaning devices. It is the perfect alternative to time-intensive spray balls and costly manual cleaning. Made of FDA compliant materials, this device is flow-through in design, meaning it requires no grease or oil in the gears. Compact and efficient, the Alfa Laval GJ A2 allows for space saving while maintaining the impact, durability, and range required for optimal rotary impingement tank cleaning in sanitary environments.

Working principle

The Gamajet range of high impact tank cleaning devices combine pressure and flow to create high impact cleaning jets. Cleaning occurs at the point at which the concentrated stream impacts the surface. It is this impact and the tangential force that radiates from that point which blasts contaminants from the surface, scouring the tank interior. In conjunction with this impact, the device is engineered to rotate in a precise, repeatable and reliable, 360° pattern. This full-coverage, global indexing pattern ensures the entire tank interior is cleaned, every time.
