Replacing the Air Chamber on a Birchmeier Backpack

Andrew Greess, at, knows a thing or two about Birchmeier Backpack sprayers and all their parts. Not only does QSpray sell the products and parts, but they repair them as well. A part that sometimes wears down and cracks is the air cylinder. It is understandable as an extreme amount of pressure gets put into this piece, repeatedly.

Occasionally, with time and pressure, it cracks at the seam and needs to be replaced. Easily diagnosed as you'll hear air hissing from said crack. Visit to order all your Birchmeier Backpack sprayer parts.

Andrew Greess: Hi, this is Andrew Greess at Quality Equipment, Today, I'm talking about the Birchmeier Backpack and some of the key components you may want to consider doing maintenance on or replacing.

Today, I'm talking about the air cylinder. This is the area where the pressure builds up that allows your backpack to spray. This just is an air cylinder that screws right into the pump assembly here.

Occasionally, this will wear out. It'll crack, it'll crack right here. This will need to be replaced. You'll know it really easily because you'll hear air whistling out of it. If you need a pump cylinder for your Birchmeier Backpack, please come visit us at
