400 Series

The 400 Series brings together compatible components and accessories built to work with 400-series respiratory facepieces and physician beam scales. If you're maintaining 3M reusable respirators or keeping a mechanical scale mobile between exam rooms, this is where you'll find the specific parts that fit — no guessing at cross-compatibility.

For respiratory protection, the 3M Particulate Filters 2071 are the workhorse here. Rated P95, they capture solid and liquid oil-free particulates and attach directly to 3M 6000, 7500, 7800, and Ultimate FX FF-400 Series facepieces. The bayonet connection means they seat quickly during a shift change or a fresh setup, and their low-profile design keeps the wearer's field of vision open — a real consideration for anyone working a full day in a half or full facepiece. Buyers stocking a respiratory program usually keep these on hand in volume, since filter replacement is routine rather than occasional.

On the equipment side, the Health O Meter Wheel Assembly (55000) is the optional add-on that turns a 400 Series beam scale into a portable one. Clinics that share a single accurate mechanical scale across multiple stations get the most out of it — the wheels let staff roll the scale where it's needed instead of dedicating one to each room. It's a straightforward retrofit for the beam scale platform rather than a standalone product, so pair it with the 400 Series scale it's meant to support.

The common thread across this collection is fit-specific compatibility: these items exist to keep a particular respirator or scale doing its job. When ordering, confirm the model number on your existing equipment matches the accessory before you buy, since 400 Series parts are designed for their host device rather than universal use.
