Made of silicone rubber for better durability and will hold its shape even in extreme heat and cold. The double sealing flange provides an improved face-to-mask seal and a deep chin pocket provides a better, more comfortable fit. The replaceable polycarbonate lens offers a wider, distortion-free viewing area with an anti-fog, anti-scratch coating. The unique “over the shoulder” hose design clips at the collar and an adjustable belt holds the air hose out of the way of work. Includes NIOSH approved respirator(s).

The PN 9825-EF Cold Air Blower must be placed in clean, Grade “D” breathable air (as specified by 29
CFR 1910).
Contributing factors to the output temperature include, but are not limited to: length of the hose, ambient
temperature, and outside temperature where the hose is placed. Also, please remember that a small
temperature difference of 3° to 10° F (-16.11° to -12.22° C) is very significant when the air is blowing directly
onto the user’s face and into breathing passages.
