Thwaites Air Filter Rain Cap - OEM Number: T15463

The Thwaites Air Filter Rain Cap (OEM T15463) is a genuine replacement intake protection cap designed for use on a range of Thwaites site dumpers and construction equipment. It is fitted to the top of the engine air intake system and serves to prevent rainwater, debris, dust, and other contaminants from entering the air cleaner assembly while maintaining unrestricted airflow to the engine.

Manufactured to OEM specifications, this rain cap is engineered for durability and reliable performance in demanding construction environments. The hinged design automatically opens during engine operation as intake airflow increases and closes when the engine is stopped, helping to protect the air filtration system from moisture ingress and contamination.

FUNCTION AND OPERATION

• Prevents rainwater entering the engine air intake system
• Protects air filters from debris and environmental contaminants
• Opens automatically during engine operation
• Closes when the engine is switched off to prevent water ingress
• Helps maintain air filter efficiency and engine performance
• Designed for demanding construction and site environments

TECHNICAL DETAILS

• OEM Part Number: T15463
• Type: Air intake rain cap / pre-cleaner cap
• Function: Air intake protection component
• Application: Thwaites dumper engine air intake systems
• Construction: Heavy-duty steel or composite intake cap assembly
• Design: Hinged self-opening weather protection cap
• Installation: Direct replacement for compatible intake stacks

Rain caps of this type are commonly fitted to vertical air intake systems on construction, agricultural, and industrial machinery where protection from weather and airborne contaminants is essential.

TYPICAL APPLICATIONS

Suitable for a range of Thwaites equipment, including:

• Thwaites 3 Tonne dumpers
• Thwaites 5 Tonne dumpers
• Thwaites 6 Tonne dumpers
• Thwaites 9 Tonne dumpers
• Thwaites Power Swivel dumpers
• Engine air intake and filtration systems

Similar intake rain caps are widely used on dumper, roller, agricultural, and industrial equipment fitted with vertical air intake stacks.

IMPORTANT INFORMATION

Always confirm the correct OEM part number, intake diameter, and machine model before ordering, as air intake rain caps vary considerably in size and mounting configuration between engine installations. A damaged, seized, or missing rain cap can allow water, dirt, and debris to enter the air cleaner system, potentially leading to premature air filter blockage, reduced engine performance, and increased engine wear. During replacement, it is advisable to inspect the complete air intake system, including the intake stack, clamps, air cleaner housing, and filter elements, to ensure optimum engine protection and long-term reliability.
