The ErgoQIC is a strong and durable full flow quick coupling with no air restriction inside the coupling. ErgoQIC features a ball valve coupling with safety features offering the highest air flow. Suitable for most assembly tools, drills and grinders, it is designed for a minimum pressure drop to reduce energy consumption. The bodies of the couplings are made of hardened steel with a no-leakage design for long service life and heavy duty applications. Upgrading any air system with ErgoQIC will give the benefits of productivity and energy efficiency.
