Radial Seal Air Filters
Unique 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.
