Not necessarily true. If you do your homework, you’ll find a lot of good Catch Cans on the market. You will also find a lot of products that claim to be Catch Cans but have no internal design or baffling to create the optimum amount of pressure drop to pull the oil out of the vapor. We have engineered and designed many features in our Catch Can that we feel add a lot of value. To name a few, our Catch Cans have a Stainless Steel mesh, internal baffling, dual chamber containment, and a hard anodized finish to prevent corrosion. In addition, the Base of our Catch Can is removable to allow complete inspection of all internal components and ease cleaning.
As I said, there are a lot on the market, go with a company you can trust. There's a lot of junk Catch Cans on the market that claim great results, but are nothing more than empty beer cans. Install our Catch Can downstream of many of the imitation catch cans and you'll be amazed at how much oil still gets through the cheap brands.
