CLEAN AIR CRITICAL TO PERFORMANCE
Clean air is essential to the performance and life of your engine. Proper air filtration is important because a small amount of dirt can cause a tremendous amount of engine damage.
Baldwin offers a wide range of air filters to provide the protection your engine needs. With over 2,200 air filters in our line, Baldwin filters supply the necessary protection for all types of engines.
For efficient combustion, a modern diesel engine requires several thousand times as much air as it does fuel. Under normal operating conditions, to burn one gallon (3.79 liters) of fuel you have to clean 15,000 gallons (56781 liters) of air. Add a turbocharger to that engine, and air consumption requirements increase by 20% or more.
Proper air filtration is important because a small amount of dirt can cause a tremendous amount of engine damage. The purpose of the air filter is to promote long system life by keeping damaging contaminants away from sensitive engine components.
To improve dust holding capacity and air flow, Baldwin Filters uses two proven methods to separate and stabilize the pleated media.
PermaPleat® – an embossing process that forms dividers between pleats to prevent bunching and ensure uniform air flow.
Beading – a continuous bead of adhesive around the circumference of a filter’s metal wrap, either inner or outer, to lock the pleat tips in place and prevent movement.
CHANNEL FLOW® AIR FILTERS
Channel Flow Air FilterBaldwin Filters’ patent pending Channel Flow air filters provide superior filtration solutions in a lightweight, compact design for easy installation in less space. This straight-through air flow technology not only allows for less installation space, but offers manufacturers flexibility in design configuration.
The Baldwin Design
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 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.
The key to the Channel Flow filters is the element. 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. Elements can be formed in either a round or racetrack design. Alternating channels are sealed with a bead of adhesive as the media pack is formed.
Air enters an open channel on the inlet side and flows through the media and exits through an adjacent open channel. Contaminants remain trapped within the channels and won’t dislodge during servicing.

This straight-through air flow technology not only allows for less installation space, but also offers manufacturers flexibility in design configuration.
EXTREME PERFORMANCE AIR FILTERS
Ideally suited to demanding high dust environments, Baldwin’s Extreme Performance air filters offer fleet operators significant benefits over conventional cellulose-only media:
Higher initial efficiency for greater engine protection and life
Greater capacity for extended filter replacement intervals
Baldwin’s Extreme Performance air filters utilize ProTura® nanofiber technology. ProTura nanofiber, bonded to cellulose media, provides unequalled performance, particularly with submicron contaminants.
The Baldwin Design
ProTura nanofiber air filters feature a lattice-like structure composed of submicron diameter fibers bonded to cellulose media. This structure provides filtration that is markedly different from that which can be achieved with conventional cellulose media alone.
With ProTura media, fine contaminant particles – down to the submicron level – tend to load on the media surface rather than penetrating deeper into the media. The result is higher initial contaminant removal efficiency and lower flow restriction.
Over time, these submicron particles tend to form a “cake” of contaminant on the media surface and, from normal application vibration, tend to fall from the media to the bottom of the housing (on the dirty side of the filter). More submicron particles then collect on the filter surface and this process is continuously repeated. The contaminant is removed from the housing by the housing dust ejector. As a result, the filter is able to capture greater amounts of contaminant than filters with conventional media during a normal service interval. Extreme Performance filters enable extended filter replacement intervals.
While nanofiber cannot be seen with the naked eye, the Baldwin ProTura base sheet is yellow to distinguish it from conventional media. All Baldwin Extreme Performance heavy-duty air filters will be identified with an “XP” part number suffix.
RADIAL SEAL AIR FILTERS
Radial Seal Air FilterUnique design advantages not only improve strength and ease of service, but contaminant holding capacity and removal efficiency as well. These advantages make Baldwin Radial Seal air filters the best choice as the aftermarket replacements for popular applications.
The Baldwin Design
Every Baldwin air filter is designed to have an efficient balance of three important characteristics – maximum efficiency, minimum initial restriction and cost-effective service life.
The primary components of a typical heavy-duty Radial Seal air filter are the seal, molded ends, inner and outer metal wrappers and the media. The metal wrappers protect the filter media and provide structural strength for the completed filter. With 73 percent of the surface area of all Baldwin metal wrappers open, minimal air flow restriction is attained.
The most important part of the air filter is the media. Baldwin ensures maximum strength and minimum restriction through its PermaPleat® design. PermaPleat is a special embossing process, which creates built-in pleat spacing in the media. This adds extra stability and separation to prevent pleats bunching together from incoming air.
To complete the process of air filter construction, a urethane compound is used to form the molded ends and bond the media pack, which includes the inner and outer metal wrappers, forming a strong, yet flexible package. The heavy-duty radial seal gasket formed from this urethane compound is designed to make servicing easier and more cost effective.
