North 770030M Half Facepiece Respirator Medium

Product Description

The NORTH 770030M is a half facepiece respirator from the 7700 Series, designed for use with threaded cartridge and filter assemblies in industrial and occupational breathing protection applications. Constructed from silicone, the facepiece delivers a durable, flexible seal across a range of face profiles. The medium size fits most adult wearers and uses a 2-point suspension harness to secure the mask during use. Licensed safety professionals, industrial hygienists, and tradespeople across construction, manufacturing, and chemical handling environments rely on this respirator as a foundational piece of personal protective equipment.

The 770030M is suited for environments requiring half-mask respiratory protection, including painting, surface preparation, chemical processing, and general industrial maintenance. The threaded connection accepts compatible cartridges and pre-filters for customized hazard protection. The silicone construction is appropriate for workers with sensitivities to natural rubber latex. This respirator is also rated compatible with supplied-air respirator (SAR) and powered air-purifying respirator (PAPR) configurations, expanding its use into higher-hazard environments where ambient air supply is not adequate.
