J+A JetaÂ® Grit Trap. The J+A JetaÂ® grit trap is a high performance, compact grit removal unit, whose unique impeller offers the highest possible grit removal in a small plan area.
Foreline traps are placed between a high-vacuum pump and backing pump or between a chamber and roughing pump. The primary application is preventing oil vapor migration from the backing/rough pump backwards along the foreline (backstreaming).
