The Willson Dustite respirator is an American industrial half-mask.
Overview[]
The Dustite series masks use a facepiece universal to all the Dustite variants. This facepiece is made of black natural rubber and has a shape that accommodates the user's face. The filter and a wire mesh are housed in the front in a circular assembly with a cover screwed on. The nose part has a metal clamp that helps to maintain the shape of the rubber. The mask is worn using one strap that goes behind the head.
Kit[]
The kit comprises of six accessories that are universal with each variant of mask. (Except the No.1)
- The Dustite No.1, 2, 2D, 11, or 22 facepiece
- an envelope to store the loose components
- a stack of spare filter pads
- spare inlet valve discs (not included in the No.1 kit)
- A “Facelet” (a stretchy fabric cuff that goes over the edges of the mask to prevent skin irritation and allergic reactions from the rubber while in use)
- a cardboard storage box that is printed with the masks name and instructions
Variants[]
The Dustite series masks came in multiple different variations as listed below.
No.1- presumed to be the same as the No.2 except it is missing the outlet valve Assemblies.
No.2- the improved model, it uses a metal screw thread and appears to be the first model to use the dual outlet valve assembly.
No.2D- about the same as the No.2 but uses an all-plastic screw thread instead of a metal one.
No.11/22 nothing is known about these models. It could be that they were a slight improvement or maybe they used different filter pads.
