Compatible with the IAS 3 interface (LEX 3) and IAS 2 interface (LEX 2 and LRS). Compressed air, extraction, and exhaust in one hose ensure safety during work and in the results. The exhaust routing in the hose prevents oil on the surface, cold exhaust on the hands or forearms, and protects health. The IAS hose is used when working with pneumatic grinders such as the LEX 2, LRS, or LEX 3 in oil-lubricated operations. The 3-in-1 hose and IAS interface are easy to use and save time during tool changes. Additionally, the three-way equalization allows for smooth and fast work.
