Klein Tools Hard Hat Cooling Fans

Klein Tools offers cooling fans designed for use with their hard hats and safety helmets—with patent-pending accessory mounts for easy attachment and removal. The dual-fan design forces outside air into the shell to push out stale hot air, facilitating cooling. Included long and short ducts can be configured 16 different ways for efficient airflow. These fans are powered by a detachable, rechargeable lithium-ion battery that can also charge other small USB devices.
