A spray wand carrier for Vario Gun and spray tube is also added, plus it has a large opening with filter to allow easier refill. Additionally, a fine filter was included in the shaped suction bend and the pump fixation is improved to ensure efficient application every use. This backpack sprayer has a 4-gallon capacity tank and weighs 4.7 kg.
We have been using these sprayers for years. I have never thought they were made cheaply and we recently bought another one with the interchangeable pump lever. I can't imagine where one would leak. We beat them up quite a bit and when something wears out you rebuild it and it is like new.
Done with Birchmeier. I've been using Birchmeier for 12+ years and this new version is simply horrible. The new piston assembly is designed not to leak yet I'm about to replace my second assembly...for $100 and the backpack isn't even 3 years old. I can purchase an entirely new Chaplin backpack for under $100.
So... I'm going to purchase a Chaplin.
So long Birchmeier, let me know if you decide to manufacture well built sprayers again.
I'll very well made sprayer, durable and easy to use, and been a four gallon sprayer, your spray more with less fill ups, but if you prefer two gallon or less, you can fill it up to the desired amount of liquid, excellent product.
