Working in an environment where the temperature is comfortable is key to maximizing productivity. The rpb C40 Climate Control Device can heat and cool your supplied air as desired. With the slide of a lever, your employees can switch from heating to cooling ensuring they are comfortable whether they're in the searing heat of the Arizona summer, a severe Scandinavian winter or anywhere in between. The rpb C40 can cool incoming air by up to 52 deg F (29 deg C) or heat it by up to 33 deg F (18 deg C). This is achieved by simply switching the mixing lever from hot to cold. The device is lightweight and ergonomically designed to sit comfortably on the operator's hip. The rpb C40 pairs with most of our respirator range.
