50713340 ORDER SPECIFICATIONS.pdf

This document is a detailed specification for a Powered Air Purifying Respirator (PAPR) Welding Hood, outlining comprehensive technical requirements for a respiratory protection system designed for welding and industrial applications. The specifications mandate a complete system including components such as a blower assembly, HEPA filter, batteries, battery charger, flowmeter, helmet assembly, and multiple specialized features. Key technical requirements include NIOSH and ANSI certifications, a high-efficiency particulate air filter that protects against hazardous metal fumes, an ergonomic four-point headgear design, flame-resistant head seal, and advanced lens technology with four operating modes for welding, cutting, and grinding applications.

The system must have specific performance characteristics, including a lightweight low-profile blower (under 2.2 pounds), dual air speeds, 1,200 hours of battery life, a quick-release belt design, and a switching speed of 1/20,000 second. Additional specifications cover battery performance (two batteries per system, 500 charge rating), airflow rates (197 lpm low flow, 215 lpm high flow), a 3-hour maximum charging time, and precise dimensional requirements for the blower (8 inches height, 8.5 inches width, 3.25 inches depth). These detailed specifications align with a Defense Logistics Agency Maritime solicitation (SPMYM225Q2397) for a small business set-aside commercial procurement of PAPR welding hoods to be delivered to Puget Sound Naval Shipyard.
