Gentex Pureflow® ESM+ PF50
PAPR System


Powered Air Purifying Respirators


All-in-One Head Mounted Powered Air Purifying Respirator. Enhanced for Maximum Mobility and Protection in Light Duty Industries.

The PureFlo ESM+ PF50 PAPR is revolutionizing the industry. With full NIOSH approval, this advanced all-in-one system is ideal for light duty industries, such as Pharmaceutical and Laboratory environments. The bump cap offers a lighter more comfortable design while the neck cape can be wiped down or laundered.

We’re confident you’ll love the benefits PureFlo has to offer – superior performance, comfort, durability and unmatched value. Take advantage of a 30-day, risk-free trial of up to two (2) of our next generation PAPRs through our “Try PureFlo On. Risk-Free” program. Buy it, try it, and if you don’t love it, return it.

Getting the job done shouldn’t mean sacrificing safety. With PureFlo, you and your team can stay protected while increasing output performance.
