E220 EX

Estalky E220 EX is a newly launched intrinsically safe 4G smart PoC radio, designed to deliver high-performance communication and digital management for business users operating in hazardous environments with combustible gas or dust. It meets rigorous intrinsically safe explosion standards: II 2 G Ex ib IIC T4 Gb IP68 & II 2 D Ex ib IIIC T120°C Db IP68.

E220 EX runs on the Android OS, empowering users to run mainstream third-party PTT applications (such as Zello, GXINPOC, etc.) for instant group communications over 2G, 3G, or LTE networks. It is widely applied in industries such as oil & gas, chemical plants, refineries, security, and utilities.

Featuring a clear HD touch screen combined with a physical semi-keypad, it offers intuitive and efficient operation. Built with an advanced AI noise cancellation algorithm and a powerful 3W speaker, it ensures loud and crystal-clear audio even in extreme industrial noise. Additionally, it is equipped with cameras for real-time video dispatching, and a reliable explosion-proof battery for all-day, multi-shift operations.
