Choosing a Prep Pro Model
When you are looking for an air filtration uint, there are many factors to consider. The key factors are: The size of the unit, the CFM and the type of filtration.
The Prep Pro Model that you choose will likely be a mix of factors including initial cost, operating cost, size, mobility, and other key factors you may determine are important. The Prep Pro 2000 is the smallest and easiest to move from place to place, The Prep Pro 4000 is the ‘middle ground’ of size and mobility, and the Prep Pro 6000 is the largest and while mobile, it’s larger size limits the ease of movement in a smaller environment somewhat. It is likely that your choice will depend on the answers to the following question:
What is the largest unit that:
- Will fit in the available space that have
- Will not conflict with my mobility requirements
CFM is an abbreviation of “Cubic Feet per Minute”, and is a measure of the rate at which air moves through a given space. There are no industry requirements determining the exact CFM you “must” use with this type of air filtration system, but the larger the space, the more air you will need to filter (increased CFM).
| Outer Dimensions|
|Prep Pro 2000||86 In.||34 In.||38 In.||1,660||1 hp|
|Prep Pro 4000||86 In.||56 In.||40 In.||2,880||2 hp|
|Prep Pro 6000||86 In.||80 In.||40.25 In.||4,220||2 hp|
Exhaust filters are designed to remove particulates from the air stream before the exhaust air leaves the unit. Prep Pro units also have V-Bank “active carbon” filters to remove fumes and solvents from the air, so that you are not breathing these fumes as you work. Fumes from formaldehyde, diesel, adhesives, paint, even that “Rotten Egg” smell from hydrogen sulfide and mercaptans are removed. This filter type also exhibits superior performance in removing VOCs (Volatile Organic Compounds) from gasoline, solvents, and nicotine. These filter media types are standard filter sizes and types, available from Marathon directly or your local filter supplier. To change the filters, you simply pop the used one out of it’s frame (please dispose of them according to applicable regulations) and insert the replacement filter.
