The Head Cooler Insert uses the same elements and parts - fan, rechargeable AA batteries, recharger plug, off/on switch - as the Company used in its Cool Hard Hat and Cool Cap - both of which met the OSHA standard as Type 1 Class G&G hard hat. The size of the Head Cooler Insert fits higher inside the hat after proper installation; and it will meet the requirements for the OSHA standard when installed in your hat. In addition, the airflow generated with the Head Cooler Insert makes the heat reduction inside your hat with a Head Cooler installed will have the same effect as shown below
An additional feature of the Head Cooler Insert results from the fabrication process in which all of the electrical components, contacts and wiring are hermetically sealed in plastic so that there is no potential for release of any spark. Coupled with the design, this makes the Insert intrinsically safe.
