SENLYON manufactures custom stainless steel air cleaner housings for heavy-duty trucks, construction machinery, agricultural equipment, generator sets and industrial vehicles. Each housing can be built around the specified filter element, airflow path, mounting position and equipment space, with OEM options for size, connections, brackets and finish.
Custom Air Cleaner Housing Manufacturer for Industrial Equipment
Air cleaner housings are rarely selected by external diameter alone. The housing must fit the filter element, available installation space, airflow path, inlet and outlet connections, mounting points and maintenance requirements of the equipment.
SENLYON manufactures stainless steel air cleaner housings based on standard configurations, customer drawings, filter-element specifications or reference samples. A 15-inch configuration can serve as a starting platform, while the overall height, port arrangement, mounting brackets and internal filter-support structure can be adjusted for the required application.

Are Stainless Steel Air Cleaner Housings Custom-Made?
Most industrial air cleaner housings are supplied as a standard base design with customized fitment details. Even when two machines use a 15-inch housing, they may require different filter elements, outlet diameters, mounting brackets or installation directions.
Common customized items include:
Housing diameter and overall height
Filter element diameter, length and sealing dimensions
Air inlet and outlet size, direction and position
Side mounting, bracket mounting or equipment-specific installation
Left-side or right-side configuration
Internal filter positioning and support structure
Access cover and filter replacement method
Stainless steel grade or alternative metal material
Polished, mirror-polished, painted or specified surface finish
Brackets, straps, clamps, fasteners and connection accessories
Air Cleaner Housing Applications
Engine Air Intake Systems
For engine air-intake applications, the housing protects and positions the filter element while directing filtered air toward the engine intake system. The design must be matched to the required airflow, allowable pressure drop, inlet and outlet sizes and available installation space.
Typical equipment may include heavy-duty trucks, construction machinery, mining vehicles, generator sets and other large-displacement power equipment.
Cab Air Filtration Systems
Cab air filter housings are used in equipment cabins and vehicle ventilation systems. They provide an enclosure for the specified filter element and support the delivery of filtered air into the operator environment.
These housings can be designed for construction machinery, agricultural equipment, special-purpose vehicles, mining equipment and industrial vehicle cabins.
Industrial Machinery Ventilation
Custom metal filter housings can also be used in machinery ventilation and equipment air-filtration systems where the filter element requires protection from dust, vibration, impact and external working conditions.
The intended application—engine intake, cab ventilation or industrial equipment filtration—must be confirmed before the housing structure is designed.
Stainless Steel Material and Surface Finish
Stainless steel is commonly selected for air cleaner housings used in outdoor, dusty or corrosive industrial environments. SUS304 can provide a combination of corrosion resistance, appearance and fabrication performance for compatible applications.
A polished or mirror-polished exterior can improve surface smoothness and make dirt easier to remove. The required finish should be selected according to equipment appearance, cleaning requirements and the operating environment.
Carbon steel and other customized materials may also be considered when required by the equipment design, cost target or surface-coating system.
Important Engineering Considerations
Filter Element Compatibility
The filter element is the starting point of the housing design. Buyers should provide the filter part number, technical drawing or physical sample so the internal support, sealing area and maintenance clearance can be matched correctly.
Airflow and Pressure Drop
The inlet, outlet and internal airflow path should be sized according to the equipment’s airflow requirement and allowable pressure loss. A large external housing does not automatically provide suitable airflow if the ports or internal path are incorrectly designed.
Mounting and Vibration
Industrial vehicles and machinery operate under continuous vibration and mechanical shock. Mounting brackets, straps, fasteners and welded joints should be designed according to the housing weight, installation position and equipment operating conditions.
Dust and Weather Exposure
For equipment working in mining, agriculture, construction or long-distance transportation, the design should consider dust, rain, mud, temperature changes and external impact. Required water-control or sealing features must be identified in the technical specification.
Filter Replacement Access
The cover and mounting position should leave enough space for routine inspection and filter replacement. Buyers should confirm the available service clearance before approving the housing drawing.
Applications Across Industrial Vehicles and Machinery

Production and Quality Control
Production can include material preparation, cutting, forming, welding, surface treatment, assembly and final inspection. Quality-control items may include:
Material and thickness verification
Housing diameter and height inspection
Inlet and outlet dimensional inspection
Mounting-hole and bracket-position inspection
Welding quality inspection
Surface-finish inspection
Filter element fit checking
Cover and accessory assembly inspection
Final appearance and dimensional confirmation
If airflow, leakage, vibration or equipment-specific functional testing is required, the acceptance method should be agreed before sample production.
OEM Air Cleaner Housing Development Process
Requirement review: The buyer provides the equipment model, application, filter specification and installation information.
Technical confirmation: Housing dimensions, ports, mounting points, materials and surface finish are reviewed.
Drawing approval: The technical drawing is checked and approved before manufacturing.
Sample production: A prototype or sample order can be produced for dimensional and installation evaluation.
Fitment verification: The buyer confirms filter fit, equipment mounting and maintenance access.
Bulk manufacturing: Production begins after the approved sample and order requirements are confirmed.
Inspection and packing: Finished housings are inspected and packed for domestic or international shipment.

Frequently Asked Questions
Are stainless steel air cleaner housings standard or custom-made?
A standard size such as 15 inches can be used as the starting configuration, but filter fit, overall dimensions, air connections and mounting structures are commonly customized for the equipment.
Can the housing fit a customer-specified filter element?
Yes. Provide the filter part number, dimensions, drawing or physical sample so the internal support and sealing structure can be designed accordingly.
What is the difference between an engine air cleaner housing and a cab air filter housing?
An engine air cleaner housing supplies filtered air to the engine intake system. A cab air filter housing supports the ventilation or HVAC system that supplies filtered air to the operator cabin. The required application must be confirmed before design.
Can the mounting brackets and air connections be customized?
Yes. Brackets, straps, mounting holes, inlet and outlet sizes, connection positions and installation directions can be customized.
Can SENLYON produce a sample before bulk manufacturing?
Sample development and trial orders can be discussed according to the product specification, tooling requirements and order plan.
