The Pureflo Pureweld ESM with Nexgen powered air purifying respirator (PAPR) helmet is the ultimate personal safety solution for welding applications and industrial environments. The Pureweld ESM full face respirator with Nexgen welding shield provides an all in one respiratory, eye, face and head protection against airborne particulate contaminates including hexavalent chromium applications, flying debris, sparks, cutting, chemical and molten metal splashes.
With no belt pack, down hose or trailing leads to get in the way, the Pureweld ESM is completely self contained, easy to use and convenient allowing the wearer to be able to move freely without restrictions even in tights spaces.
With an APF of 1000*, the highest allowed for PAPR full face respirator helmet unit. The Pureweld ESM combines a hard hat with the welding shield accessory into a user friendly helmet system that significantly cuts annual operating and maintenance costs.
The high efficiency HEPA filter prevents the inhalation of harmful and hazardous particulates while the face shield and hairnet combination protects the wearer from impact, head, eye and face hazards.
The Pureflow ESM unit is NIOSH approved under 42CFR part 84. The hard hat meets ANSI Z89.1+ (high impact) along with Pureweld Welding Shield accessory. FM Approvals include Class I, II, III Div 2 ABCDEFG. The normal flow rate is 7.6 cfm with an optional “Boost” rate of 8.2 cfm that’s available.
The Pureweld ESM incorporates an on board CPU system that constantly monitors filter usage, battery life and airflow to ensure optimum performance at all times.
With a APF of 1000, the Pureflow ESM was independently tested to a minimum average of 31,000.
