More Surface Area
Baldwin’s Channel Flow filter has more surface area than a traditional air filter, while requiring the same or less installation space. The Channel Flow media is formed by layering alternating rows of flat sheets and corrugated media. When completed, the media resembles a honeycomb network of channels. As the media pack is formed, alternating channels are sealed with a bead of adhesive. Air enters open channels and flows through the media and out through adjacent open channels.

Increased Capacity
Traditional air filters have an average capacity of about 1 unit of contaminant per unit volume, where as the Channel Flow filter holds 2 units of contaminant per unit volume. This gives Channel Flow twice the capacity of traditional air filters.

High Efficiency
Tests show Channel Flow filters have an average efficiency of 99.99%. This means for every 10,000 units of contaminant introduced to the filter, only one makes its way through. This is comparable to the efficiency of Baldwin Filters’ traditional heavy-duty air filters.

Decreased Flow Resistance
Increased air flow is needed for higher performance engines. Increased air flow is also needed to meet tougher exhaust emission standards. With a traditional air filter, air typically enters through the side of the filter housing. The air must then work its way around the filter element, pass through the media, then turn 90° to exit the filter. By eliminating the turns the air needs to make in a traditional air filter, in-line air filters reduce restriction.
