The JM008 Explosion-Proof Wall-Mounted 4G WiFi Jammer is a professional-grade signal blocking system designed for industrial safety and security. It operates across 8 frequency bands to effectively disrupt 4G cellular and 2.4GHz WiFi signals within a 5-20 meter radius, depending on the ambient signal strength.
Unlike common portable jammers, the JM008 is engineered for fixed installation in hazardous or high-risk environments-such as gas stations, petrochemical facilities, and chemical warehouses-where even a small electrical spark from a mobile phone could trigger serious incidents.
Durable, Safe, and Designed for Harsh Environments
Built with a flame-red, explosion-proof aluminum alloy housing, this device not only resists heat, corrosion, and impact but also provides a strong visual safety warning for personnel working nearby. The distinctive color ensures visibility, reminding users to remain alert in flammable or restricted areas.
The die-cast shell offers both sun-proof and weather-resistant performance, making it suitable for long-term indoor or semi-outdoor use. Whether mounted on a control room wall or a factory column, the JM008 integrates seamlessly without taking up valuable floor space.
Reliable 4G & WiFi Signal Suppression
With its 16W total output power (2W per band), this wall-mounted jammer ensures stable, uninterrupted performance over extended periods. It effectively prevents unwanted communication or mobile device use, ensuring safer operations and reducing potential interference risks.
For industries that require even broader protection, users can consider upgrading to the T-US-011 High-Power 5G Signal Blocker (150W) – a top-tier model that adds 5G coverage and offers expanded range for larger industrial facilities.
