Product Description

The NORTH 770030L is a large, half facepiece respirator constructed from silicone and designed for use in industrial, commercial, and hazardous-environment applications. Part of the NORTH 7700 series, this respirator features a threaded connection type for secure cartridge attachment and a 2-point suspension system for a stable, adjustable fit. The silicone facepiece material provides durability and comfort during extended wear. Compatible with both supplied-air respirator (SAR) and powered air-purifying respirator (PAPR) systems, the 770030L offers flexibility across a range of respiratory protection configurations. It is sized large and is sold individually.

This half mask respirator is suited for professional use in environments where respiratory protection is required, including industrial maintenance, chemical handling, painting, and construction trades. The threaded cartridge interface allows for quick cartridge swaps in the field. SAR and PAPR compatibility makes this facepiece useful for tasks that require higher levels of respiratory protection beyond standard cartridge filtration alone. Licensed tradespeople, industrial hygienists, and safety professionals are the primary installers and fit-testers for this product.
