BURRELL SERIES MASKS
This page is dedicated to documenting MSA's Burrell series of masks, which were manufactured from 1920-1949 and served as their flagship facepieces during said time. Other MSA masks, such as the All-Vision and Clear-Vue, will be covered on another page.
The first full face masks to wear the "Burrell" name actually began their lives as military KTM model masks. In the "wild west" that was post-WW1 US mask development, models were being produced, and then deemed obsolete, in a matter of 2-3 years. The KTM, while being more advanced than any mask before it, met this fate as development of the M1 series of masks continued. As such, many were sold to MSA, who would later produce more KTM style masks in house.
It should be noted that the Burrell V1 was often sold by other safety companies in packaging completely devoid of any MSA logos. As such, while masks like the Pulmosan model shown to the right appear to be an independent product, they often are simply another MSA Burrell V1, in a different case with different labels.
The Burrell V2 was one of MSA's first in-house designs, and was essentially a retooled V1. The flapper valve on the chin was forsaken in favor of a "Connell" style valve designed by Max Yablick mounted on the front of the mask, and the stockinette covering was also done away with. The Burrell V? saw great success on the industrial market, and lasted for many years. They are by far the easiest of the Burrell series to find these days.
Supplied Air variants of the V2 exist, although they are extremely rare.
Sometime between the production of the Burrell V2 and the introduction of the MSA All-Vision, the mask shown to the right was produced. It is theorized that it was made as an attempt by MSA to cater to the Civil Defense or Military markets, but beyond basic guesses, no conclusions have been reached. No documents referring to this mask have ever arisen, and the lone facepiece remains unique.
The Burrell V3 can be seen more as a “premium model” of the V2 rather than a successor, as there is evidence to suggest that both masks were sold at the same time for many years. Reverting back to using a flapper exhale valve, the V3 featured a prominent speech membrane located directly in front of the user’s mouth. This feature made the mask very popular among firefighters and industrial workers.
Production of the Burrell line ended in the 1950′s, when the new “All-Vision” masks (which were cheaper, lighter and more durable) replaced the V3 as MSA flagship model.
