WHAT THEY DO & HOW THEY DO IT
Simply put, our exhaust purifiers allow you to work indoors close to a gas or propane fueled engine without any health risks. They do this by using catalytic exhaust technology to make the exhaust emissions safe to breathe. Each purifier houses a catalytic core, which cuts harmful emissions by collecting gas particles and burning off dangerous pollutants. These include particles such as Carbon Monoxide (CO) and Hydrocarbons (HC). The harmful emissions of gas or propane engines are converted into water (H2O) and Carbon Dioxide (CO2), which makes it safe to work in proximity with your machine.
WHICH IS RIGHT FOR YOU?
CLIP ON STYLE
The most cost effective and easiest to install is simply a clip-on style purifier that installs at the end of the tail pipe. We supply the purifier with the right sized muffler clamp, and it installs easily. Depending on the horsepower of the engine, the scrubber is typically the size of a coffee can. Scrubbers are physically larger for a high horsepower engine such as a 1000 HP engine in a generator. When the purifier is no longer needed, such as in a rental application, it can be removed and stored.
The other style purifier or scrubber is a direct fit combination exhaust purifier/muffler. This style is most used when there is no room at the end of the tail pipe to attach a clip-on purifier. These combination muffler purifiers are the same shape and spatial dimensions as the OEM muffler and the installation time is similar to changing out a muffler. Typically, once installed these are not removed. These muffler/purifiers usually cost up to twice as much because they are both a muffler as well as a purifier.
We also have scrubbers for Honda and Wisconsin engines. The scrubbers for the Honda’s are combination muffler/purifiers that are identical to the OEM Honda muffler in size and shape. For Wisconsin engines, we can supply a clip-on purifier, but because Wisconsin engines are inherently “dirty,” we recommend that you change the carburetor jet size, install new spark plugs, and use premium spark plug wires (such as Accel). See Tech Tip #56: Spark Plug 101, for more information on Wisconsin spark plugs. Tech Tip #26: Foley Engines Clean Air Tip, has more information on exhaust scrubbers for gasoline fueled engines.
