The Hot Shield Model HS-4 Respirator and Face Protector Housing is designed to house and protect the Sundstrom brand respirator, models SR-90 & SR-100. This Hot Shield housing does more than that...it protects your face and neck just like our popular HS-2 model! The HS-4 is constructed of CarbonX materials, the only inherently nonflammable and most thermally resistant fabric in the world today.
The HS-4 combined with the Sundstrom SR-90 or SR-100 Half Face Respirator has been designed for any and all workers who desire heat & flame protection for their face & neck yet must wear a fit test capable silicone half face respirator. Outside of a positive pressure breathing apparatus, this is a very comfortable and highly protective alternative!
The SR-100 by Sundstrom respirator is a negative pressure half face cartridge style respirator that carries NIOSH approvals for specific levels of gases, vapors and/or particulates when equipped with the appropriate chemical cartridge and/or particulate filter. The SR-90 model & especially the SR-100 is designed to provide exceptional safety and breathability for long periods of time, something for which the HS-2 is not designed.
The Sundstrom SR-100 provides a high degree of filtration, yet has easy air exchange due to twin exhalation valves. The body is made of high grade soft & flexible silicone which stays dimensionally stable and harmless to the skin. Hot Shields HS-4 Housing does not interfere with the mask fit to the face (no fabric between you and the respirator itself) which allows for quantifiable fit testing of individuals.
Goggles NOT included.
Note: The HS-4 is NO LONGER made with a black fabric covering the front inhalation filter and this is NOT an option. Sundstrom supplies a spark arrestor screen that sits right behind the outer cover of the filter.
