Donaldson Engine Air Filter Model 1027 with Folding Element and 274cm Height

This Donaldson engine air filter, identified as Model 1027 with references P821575, P822858, and G057513/G05751 components, serves as a critical filtration component for engine systems. The filter is engineered to deliver strong filtering performance while contributing to energy and fuel saving outcomes during operation. Its substantial build and specialised construction materials work together to provide moisture-proof properties and ensure no stuffiness occurs, maintaining optimal airflow to the engine. With its specific dimensions and folding filter element design, this component represents a purpose-built solution for industrial and automotive applications requiring reliable air filtration.
Features and Construction

The Donaldson Model 1027 air filter incorporates several distinctive design elements that contribute to its functionality within engine systems. From its specific material composition to its dimensional specifications, each aspect has been selected to support the filter's operational requirements in demanding environments.
Material and Build
This air filter utilises an 08 thick mesh framework combined with wood pulp filter paper to create its filtration medium. The wood pulp filter paper component provides the primary filtration surface, while the thick mesh offers structural support and maintains the filter's shape under operating conditions. This material combination contributes directly to the filter's strong filtering performance, with the wood pulp paper offering effective particle capture while the mesh prevents collapse or deformation. The materials are arranged in a folding filter element configuration, which increases the total surface area available for filtration without requiring additional physical space.
Size and Practical Fit
With dimensions measuring 106cm in outer diameter, 60cm in inner diameter, and 274cm in height, the Model 1027 represents a substantial filtration component. These measurements ensure compatibility with specific engine systems and housings designed to accommodate filters of this size category. The 274cm height provides considerable filtration surface area when combined with the folding element design, allowing for extended service intervals in many applications. The relationship between the outer and inner diameters creates the necessary structural framework to support the filter element while maintaining proper airflow characteristics throughout the filtration process.
Uses and Placement

Designed specifically for engine system applications, this Donaldson air filter serves a critical role in maintaining air quality entering combustion systems. Its construction and performance characteristics make it suitable for various industrial, automotive, and machinery applications where reliable air filtration directly impacts operational efficiency and component longevity.
Event or Professional Use
In professional and industrial settings, this air filter supports engine systems requiring consistent airflow with effective particulate removal. The strong filtering performance contributes to maintaining engine power output while the energy and fuel saving characteristics can result in operational cost reductions over time. The moisture-proof properties are particularly valuable in environments with variable humidity or where engines operate in conditions that might expose filtration systems to moisture. These combined attributes make the filter suitable for continuous operation in demanding applications where maintenance intervals need to be optimised for productivity.
Everyday Home Use
While primarily designed for engine systems that may include industrial or automotive applications, the principles behind this filter's construction apply broadly to any situation requiring reliable air filtration. The no stuffiness characteristic ensures consistent airflow even as the filter collects particulate matter, preventing restrictions that could impact performance. For users maintaining equipment with specific filtration requirements, the clearly defined dimensions and material specifications allow for accurate compatibility verification before installation.
Benefits and Buying Value

Selecting this Donaldson air filter provides several practical advantages stemming from its documented specifications and construction approach. From its material composition to its performance characteristics, each aspect contributes to the filter's value proposition in appropriate applications.
Reuse and Low Maintenance
The filter's construction using durable materials like 08 thick mesh and wood pulp filter paper supports extended service life in properly maintained systems. The moisture-proof properties help prevent degradation from environmental humidity, while the folding element design maximises filtration area to extend intervals between replacements. When maintained according to standard procedures for industrial filters, this component can provide reliable performance throughout its service life, contributing to reduced maintenance frequency in compatible systems.
Why Choose This Product
This Donaldson Model 1027 air filter offers a specifically engineered solution for engine systems requiring its particular dimensions and performance characteristics. The documented strong filtering performance, combined with energy and fuel saving outcomes, provides tangible operational benefits in appropriate applications. With clearly specified materials, dimensions, and construction details, users can make informed compatibility decisions based on concrete data rather than estimated specifications. The inclusion of multiple part number references (P821575, P822858, G057513, G05751) further assists in accurate identification and procurement for replacement scenarios.
