Many years ago Claude Maurice from Kinectrics and Hugh Hoagland from e-hazard.com and ArcWear.com collabarated to create fans for arc flash hoods. Steelgrip, NSA and Stanco all three worked with us on developing hoods. Steelgrip patented a removable design and now NSA has a new one which is removable (not breaking Steelgrip’s patent). These cooling hoods make Arc Flash Hoods more wearable and help prevent fogging of the lens. Other designs have been less effective. NSA’s new fan should be another good offering on the market.
