Used Truck A/C Compressors, Clutches & Complete Air Con Pump Units

Used truck A/C compressors, clutches & complete air con pump units

The A/C compressor is the heart of the truck air conditioning system. Driven by the engine belt via an electromagnetic clutch, it compresses and circulates refrigerant around the system so that heat can be removed from the cab. Heavy-duty truck A/C compressors are usually 24V units running R134a refrigerant and are designed to cope with long operating hours, high under-bonnet temperatures and constant vibration.

In this category we offer used OEM A/C compressors, compressor & clutch assemblies and complete air con pump units removed from complete donor vehicles. Typical examples include Sanden/TCCI SD7H15 or QP7H15 style compressors with 8-groove pulleys for MAN TGX/TGS, DAF XF/CF, Mercedes-Benz Actros and Volvo FH/FM Euro 5–6 trucks.

What you will find in the A/C Compressors & Clutches category

Stock in the A/C Compressors & Clutches category changes as new donor trucks arrive, but it typically includes:

• complete A/C compressors with integrated electromagnetic clutch and pulley for European HGVs;
• compressor & clutch assemblies built around common heavy-duty families such as SD7H15 / QP7H15 and similar designs;
• compressors with mounting brackets or rear support brackets supplied where they remain attached on removal;
• different pulley configurations (PV8 multi-rib pulleys, single or twin groove pulleys) matched to the original belt setup;
• selected spare clutches and pulleys where they can be supplied separately from the compressor body;
• other associated A/C pump components such as noise-damping covers or short connecting pipes supplied with the unit.

Each listing includes clear photos, OE/OEM part numbers where available and donor vehicle details so you can compare mounting ears, pulley type, electrical connector and hose port layout with the compressor fitted to your own truck.

Truck brands & typical applications

Most compressors in this category are taken from mainstream European heavy trucks, including:

• DAF XF and CF tractors and rigids with Euro 5 and Euro 6 engines;
• MAN TGS and TGX long-haul, distribution and construction trucks using SD7H15/QP7H15-type compressors;
• Mercedes-Benz Actros, Antos and Arocs MP3, MP4 and MP5 cabs;
• Volvo FH and FM long-distance and regional haulage vehicles;
• other brands such as Scania, Iveco and Renault Trucks when suitable donor vehicles are available.

Because these are genuine OEM components removed from complete trucks, each compressor is normally matched to a specific engine family, emission standard, belt layout and A/C pipe configuration.

Why truck A/C compressors & clutches matter

A correctly matched and functioning A/C compressor is critical for:

• effective cab cooling – without a healthy compressor, the air conditioning system cannot build the pressures needed to cool the cab on hot days or in slow traffic;
• component protection – worn, seized or internally damaged compressors can contaminate the system with debris and cause costly failures of condensers, expansion valves and other parts;
• reliability & uptime – frequent A/C breakdowns lead to workshop visits, driver complaints and reduced vehicle availability;
• driver comfort & safety – stable cab temperatures help drivers stay alert and focused over long working days.

Typical reasons to replace a truck A/C compressor or clutch

Common reasons to order parts from this category include:

• no drive or no cooling due to a seized compressor, broken shaft or slipping clutch;
• noisy operation caused by worn internal components or failing clutch bearings;
• refrigerant leaks from compressor body seals, hose ports or shaft seals;
• electrical clutch failure where the electromagnetic coil or clutch assembly has burnt out or become damaged;
• incorrect or non-original compressor fitted previously that does not match the belt, pulley or pipe layout;
• replacing a heavily corroded or accident-damaged compressor with the correct OEM 24V A/C pump for your truck brand and model.

How to choose the correct A/C compressor or compressor & clutch assembly

To minimise fitting issues and ensure reliable operation, please check the following details before ordering:

• truck brand, model and engine type – for example DAF XF106, MAN TGX Euro 6, Mercedes Actros MP4, Volvo FH4;
• emission standard – Euro 3, Euro 4/5 and Euro 6 trucks can use different compressor part numbers and mounting arrangements;
• compressor family – SD7H15, QP7H15 or equivalent design used on your existing A/C system;
• pulley type and number of grooves – PV8, multi-groove or single/twin groove pulleys must match your belt setup;
• mounting ear layout – front and rear mount positions, bolt spacing and bracket style;
• refrigerant type and voltage – most European HGVs use 24V compressors with R134a refrigerant; always confirm before ordering;
• OEM part numbers stamped on the compressor label or body, matched against the references shown in the product description.

If you are unsure, you can contact us with your VIN or registration number and clear photos of your existing compressor, pulley, label and pipe connections. Our team can help you confirm compatibility before you place an order. For general guidance, see How to Find the Right Part and Compatibility & VIN Policy.

Used OEM compressors from dismantled trucks

VRA Truckparts specialises in used OEM truck parts sourced from carefully selected donor vehicles. Trucks are inspected and documented before dismantling so that cooling and A/C systems can be assessed. During dismantling, our technicians remove A/C compressors and brackets, check housings, pulleys and electrical connections for visible damage and reject units that do not meet our standards.

Usable compressors are cleaned externally, labelled with OEM references where available and stored under cover in our warehouse ready for dispatch. To learn more about how we work, please visit Our Dismantling & Quality Process, Warranty & Part Condition and Trucks We Dismantle.
