The right compressor part starts with the right machine identity. Two parts can look identical and still differ in media, sealing geometry, pressure rating, electrical rating, firmware revision or fitment, so Reddy Compressors treats every parts enquiry as an identification problem first and a price-and-availability question second.
Start with the machine, not the catalogue
A generic catalogue answers "what is sold". A parts engineer asks "what is installed". The compressor make, model and serial number, the airend, motor, controller and engine identities, and the part number etched on the old component tell us far more than a description such as "oil filter for a 75 kW screw compressor".
Reddy Compressors supports the sourcing and selection of parts for customer-owned equipment. Compatibility, genuine or OEM status, stock, supersession, warranty and installation suitability are confirmed item by item before we quote. We do not make blanket claims such as "all parts in stock" or "genuine parts for all brands".
What to send us
The more of the following you can supply, the faster and safer the match:
- Compressor make, model and serial number from the nameplate
- Airend, motor, controller and, for portable machines, engine model and serial number
- The existing part number, any superseded number, and any number etched or cast into the part
- Clear photographs of the nameplate, the installed part, its connectors, ports and threads
- Operating hours, duty and the fault or service interval that triggered the enquiry
- Quantity, urgency and delivery location
If you have only a photograph of the part, send it. We would rather identify from a good photograph than guess from a description.
Maintenance parts and repair parts
Maintenance parts, such as filters, separators, lubricants and service kits, are replaced on a schedule. Repair parts, such as valves, bearings, seals, coolers, drive components and controllers, are replaced after a fault or on overhaul. They are identified and verified differently, and a wrong match costs different things: a wrong filter can reduce protection, while a wrong valve or bearing can damage the machine.
Part families we support
Use the pages below to see how each family is identified and what to check before ordering.
- Consumables: service kits, intake air filters, oil filters, air-oil separator elements and compressor lubricants
- Control and protection: inlet and unloader valves, minimum-pressure and check valves, thermostatic valves, sensors, transducers and solenoids, controllers and HMI
- Mechanical: airend bearings and seals, belts and couplings, oil coolers and aftercoolers
- Electrical and drive: motors and VFD components
- Air treatment: dryer parts, filter elements and drains
- Portable equipment: engine parts for portable compressors
Why look-alike parts fail
Identical appearance is not compatibility. Common mismatches include a separator element with the right thread but different media or pressure-drop behaviour, a solenoid with the right body but the wrong coil voltage, a controller with the right housing but an incompatible firmware revision, and a seal that fits but is made of a material unsuited to the lubricant. Never infer interchangeability from appearance, dimensions, brand familiarity or an old quotation.
How a parts enquiry is handled
- Identify the machine and the component from your nameplate data, numbers and photographs.
- Verify compatibility, including supersession and any modification needed.
- Quote with the part identity, its supply status, the lead-time basis and the terms that apply.
- Check on receipt that what arrived matches what was quoted before it is fitted.
- Verify after fitting that the fault is resolved and the machine runs within its normal operating condition.
Frequently asked questions
Can you supply a part if I only have the machine model?
Often we can narrow it down, but a model alone rarely settles the part. Serial number, the existing part number and a photograph remove most of the uncertainty, so please send them with the enquiry.
Do you supply genuine OEM parts?
That depends on the item and the brand. We state the supply status of each part when we quote it, and we do not describe a part as genuine or OEM-approved unless that is the case for that item.
Can you help if the part is obsolete or superseded?
Yes, we can check whether a superseding part exists and what changes it needs, such as connectors, firmware or fitting. Any modification is stated in the quotation.
Can I order service kits for a scheduled overhaul?
Yes. Tell us the machine, its running hours and the service interval, and we will identify the right kit contents so the overhaul is not delayed by a missing component.
Do you support compressors you did not sell?
Yes, customer-owned equipment is supported where the machine can be identified and the parts can be verified and sourced.
