NOTE! This is ONLY the Sundstrom WFR Kit and DOES NOT include the Hot Shield HS-4. If you want to have both , you must order the "HS-4 Combo" (which actually has 3 items, the 3rd being the Web Case storage pouch).

Our Hot Shield model HS-4 is designed exclusively to fit the Sundstrom SR-100 contained in this Wildland First Responder Kit. When both products are mated to each other, you enjoy best breathing protection (outside of a self contained breathing apparatus) and the best thermal protection for your face and the respirator itself!

Benefits at a Glance

• A superior face seal means a very high protection factor
• Easily adjustable V-shaped elastic head harness with a large crown plate
• Unique inhalation and double exhalation valve design provides one-half the breathing resistance of competitive respirators. This means easier breathing and greater respirator compliance
• Extra-large 201 square inch P100 filter area provides extremely low breathing resistance, high air flow and extended filter life
• High-efficiency P100 particulate filter offers ten times more filter effectiveness than required by NIOSH. Each filter tested for 99.997% filter efficiency against particulates and aerosols capturing 100% of items .3 microns or larger.
• Pre-filter system collects coarse particles thereby extending the life of the P100 filter
• The included Organic Vapor / Acid Gas (OV/AG) chemical cartridge can be used by itself or stacked with the included P100 particulate filter based on user’s application
• Chemical cartridge with an extra-large surface area providing high gas absorption capacity
• Easily fit tested and fit checked
• NIOSH approved

Better Protection

The Sundstrom P100 particulate filter offers an efficiency level of 99.997% which is ten times higher than NIOSH requires at 99.97%. Therefore, the Sundstrom P100 filter is 10 times more effective and offers 10 times better protection.

Greater Comfort 

This respirator is made of high grade, non-allergenic, FDA approved silicone.

Less Breathing Resistance

Sundstrom’s unique design significantly cuts inhalation and exhalation resistance making the mask twice as easy to breathe through. This increases comfort and lengthens use time. This respirator design allows breathing rates of more than 250 liters per minute as compared to most competitive products which generally allow only 95 liters per minute. This means the Sundstrom user can handle much heavier and strenuous work levels and avoid the early fatigue due to superior patented design of mask and filters.

An Adaptable System

The Sundstrom WFR Kit has a HEPA P100 filter and an organic vapor, acid gas cartridge which can be snapped onto the P100 if needed.

Cost Efficient

The SR 100 is an easy to maintain, clean and disinfect reusable mask. Further, Sundstrom employs a unique, ultra efficient and low cost Pre-Filter which prevents premature clogging of the particulate filter and extends filter life up to 5 times longer than competitive APR mask.
