Willson Respirator Facelet Lot vs Industrial Safety Sign Lot: Which PPE Shop Stash Should You Buy?

A rare vintage respirator facelet stash or a ready-to-hang mixed safety sign lot? We compare price, contents, and best use cases for both PPE shop lots.

Last updated Aug 15, 2026

Setting up a shop safety program often comes down to a fork in the road: do you invest in hard-to-find protective components for the gear you already have, or do you grab a bundle of signs and decals that tell people what to do before they get near a hazard? The choice gets even trickier when both options arrive as surplus lots.

Quick Verdict

If you maintain older Willson respirators and need genuine replacement facelets, the Willson lot is the rare find you'll want to secure. If you need practical, mixed hazard signage for a garage, machine shop, or warehouse, the industrial sign lot gives you broad coverage at a lower price. The two are not direct substitutes; they solve different problems.

Where Each Product Wins

  • The Willson Respirator Facelet Lot wins for anyone restoring vintage industrial safety equipment. It offers authentic facelets with a known part number and compatibility across a long list of classic Willson respirator series.
  • The Industrial Safety Sign Lot wins for quick visual reminders. It covers used oil, diesel fuel, fire extinguisher locations, and personal protective equipment in one mixed bundle, and it comes at a noticeably lower price.

Willson Respirator Facelet Lot

If you have a Willson 1B, 2B, 5D, 6, 11B, 22B, 45D, 55, 400, or 750DC respirator, this lot gives you 12 facelets of each style in original packaging, all under part number 20-20931. The five original Willson boxes and New Old Stock status make this a collector-grade parts find. Choose it when you need authentic components for existing respirators rather than a complete unit. The limitation is that these are facelets, not entire respirators, and the condition is New - Open box, so they are best suited for someone rebuilding or maintaining vintage gear, not a first-time buyer looking for something ready to wear out of the package.

Industrial Safety Sign Lot

This mixed lot gives you 24 pieces of hazard communication for a modest outlay. You get 10 Caution Used Oil signs or decals, 9 Diesel Fuel No Smoking Open Flames labels, 4 Fire Extinguisher directional signs, and 1 Think Safety First Wear Personal Protective Equipment sign. It comes in new condition and is made in the United States. Pick this lot if you're covering an oilfield operation, machine shop, garage, or warehouse with common hazard reminders. The limitation is that it's a surplus assortment, so you're getting a pre-set mix of different sign types rather than a coordinated set of matching sizes and styles. It works best when variety matters more than consistency.

Final Choice by Use Case

Choose the Willson Respirator Facelet Lot when your priority is maintaining or restoring classic Willson respirators with genuine facelets and you already have the matching respirator bodies. Choose the Industrial Safety Sign Lot when your priority is spreading visible hazard warnings across a shop floor and you want a practical mix of oil, fuel, fire, and PPE messages without a large outlay. Both lots have a place, but each one fits a different shopper's cart.
