Overview

Holdwell Air Filter Housing is a durable replacement canister for Thermo King transport refrigeration units. The Holdwell Air Filter Housing helps protect the engine by keeping intake air clean in demanding trailer service.

• Accepts the standard cylindrical filter element used across many SL/SLX units
• Quick strap-and-bracket mounting for straightforward replacement
• Built for reliable sealing to minimise dust ingress

Specifications and Materials

Part number: 11-9299.
Moulded canister assembly with inlet and outlet stubs, integrated drain and mounting strap boss. Supplied as housing only; filter element and straps are typically purchased separately. For Thermo King operating details and maintenance intervals, refer to the Thermo King SLXi operator manual.

Compatibility and Fitment

Designed for Thermo King SB, SL and SLX families, including many SLXi models used on Australian refrigerated trailers. The housing accepts the common cylindrical air filter element used on these units. Compare the inlet/outlet orientation to your existing canister before installation. If your unit uses a strap-mounted round canister with a side outlet and bottom drain, this housing is a likely match.

Compliance and Safety

Replace air intake components at recommended service intervals to maintain engine performance and emissions. After installation, check hose clamps and the mounting strap for security. Inspect the seal surface to confirm an airtight fit.

Trailer Applications

Suitable for single- and multi-temp Thermo King trailer refrigeration units in general freight and cold-chain service where a round external canister is required. The Holdwell Air Filter Housing provides dependable filtration for regional and long-haul applications.
