Marine Spare Parts Supplier India | UAE, Singapore, Turkey
SPERRE · HATLAPA · TANABE · J.P. SAUER & SOHN · BAUER · HAMWORTHY
Genuine, OEM-equivalent and Alang-reconditioned spares for marine starting-air and working-air compressors — Sperre, Hatlapa, Tanabe, J.P. Sauer & Sohn, Bauer and Hamworthy. Shipped worldwide in 24-48 hours.
Marine air compressors deliver high-pressure starting air at around 30 bar to start the main and auxiliary engines, as well as working, control and service air for valves, automation and deck use. Suction and delivery valve plates, piston rings and unloader gear wear on a predictable schedule, and a failed starting-air compressor can leave a vessel unable to restart its engines. Wattmare supplies air compressor spare parts for Sperre, Hatlapa, Tanabe, J.P. Sauer & Sohn (Sauer), Bauer and Hamworthy/Belliss & Morcom — genuine, OEM-equivalent or Alang-reconditioned.
Every line item is offered as genuine OEM, OEM-equivalent or quality reconditioned, so a chief engineer can match budget to criticality. Based in Bhavnagar beside the Alang ship-recycling yard, we recover and recondition low-hour components from decommissioned vessels — a sourcing channel no European trader can match on price or lead time. We also supply main engine, turbocharger, auxiliary engine and reconditioned marine parts under one quote, with confirmed orders dispatched worldwide in 24-48 hours.
ANATOMY OF A MARINE AIR COMPRESSOR
A two-stage marine air compressor — the same architecture as Sperre, Hatlapa, Tanabe and Sauer reciprocating units. These are the wear parts that keep starting air on the receivers.
Every part you see, we supply — genuine, OEM-equivalent or reconditioned from Alang, dispatched in 24–48 hours.
WHAT WE SUPPLY
From a single valve plate to a complete top-end overhaul — matched to your compressor model, inspected and measured before it ships.
EVERY WEAR PART
Valve plates, piston and ring sets per stage, unloaders, gaskets and O-rings — supplied to the exact Sperre, Hatlapa, Tanabe, Sauer or Bauer model on your nameplate.
INSPECTED & MEASURED
Reconditioned pistons, cylinders and valve assemblies are dimensionally checked against the maker's wear limits and pressure-tested before dispatch, with condition notes shared first.

THE KNOWLEDGE DESK
Not every air compressor part needs to be genuine OEM. Wattmare quotes three grades on every line so the decision sits with the engineer. Genuine parts carry the maker's box and full traceability for class-critical components. OEM-equivalent parts are produced to the same drawings and material specification by established marine manufacturers, typically at a meaningful saving. Reconditioned parts — our Alang speciality — are recovered from low-hour decommissioned compressors, inspected and restored to within wear limits.
Bhavnagar sits beside Alang, the world's largest ship-recycling yard. When a vessel is recycled, its air compressors are frequently in serviceable, low-hour condition. We recover cylinder heads, cylinders, pistons, crankshafts and valve assemblies, then crack-test, pressure-test and dimensionally inspect each item. For a non-class-critical spare on an older compressor, a reconditioned part at a fraction of OEM cost keeps the vessel trading. This applies equally to our reconditioned marine spare parts across the whole engine room.
The unloader off-loads the cylinders during start-up and when the air receivers reach pressure, while the auto-drain clears condensate from the separators. A worn unloader or a stuck auto-drain is one of the most common reasons a compressor runs continuously, overheats or fails to build pressure. We supply complete unloader and auto-drain kits alongside the auxiliary engine and main engine spares those starting-air systems serve.
Air compressors feed the starting-air system that turns the engine until it fires — they don't replace it, but a vessel that can't make air can't start its engines. If your engine smokes or loses power once running, that is more likely a turbocharger fault — see our turbocharger spare parts range for matched cartridges and components.
Air compressor ranges share castings across models, and a single character in a model number changes the valve plate, ring or bearing grade. We verify every part number against the maker's parts list, the nameplate model and the stage before quoting, which is why the nameplate photo matters. This discipline carries across our full auxiliary engine spare parts catalogue and prevents the wrong-part delays that cost vessels days.
FAQ
We supply spares for Sperre, Hatlapa, Tanabe, J.P. Sauer & Sohn (Sauer), Bauer and Hamworthy/Belliss & Morcom marine air compressors, covering the common starting-air, working-air and high-pressure platforms. If your compressor is not listed, send the nameplate and we will confirm availability.
A starting-air (main air) compressor charges the air receivers to around 30 bar so the main and auxiliary engines can be started. A working-air or control-air compressor supplies lower-pressure service and instrument air for valves, automation, soot blowing and general deck use. We supply wear parts for both duties across all six brands.
Suction and delivery valve plates are the fastest-wearing part of a marine air compressor and are typically inspected and renewed every 4,000-8,000 running hours, sooner if delivery temperature or pressure starts to drift. We supply complete valve service kits with plates, springs and gaskets per stage.
Yes. We stock unloader assemblies, solenoid and pneumatic auto-drain valves, and the seals and O-rings that go with them. A worn unloader or a stuck auto-drain is one of the most common causes of a compressor that will not build pressure or runs continuously.
Both. We quote three grades on every line item where available — genuine OEM, OEM-equivalent and quality reconditioned — so you can match spend to how critical the part is. The choice is always yours.
The compressor maker and model from the nameplate, the stage (1st or 2nd), and the part number from the maker's parts list. A clear photo of the compressor nameplate and the worn part is usually enough to confirm the exact item.
Confirmed orders for in-stock and Alang-sourced parts are dispatched worldwide within 24-48 hours, including air freight to UAE, Singapore, Europe and major ports for vessel-down situations.
Bhavnagar sits beside Alang, the world's largest ship-recycling yard. We recover low-hour air compressor components from decommissioned vessels and recondition them, giving lead times and prices that traders sourcing only from OEM channels cannot match.
Reconditioned items are dimensionally inspected against the maker's wear limits, crack-tested and pressure-tested where applicable. Valve plates, pistons and cylinders are measured and condition notes are shared before the parts are packed.
Yes. Alongside the compressor itself we quote air-receiver mountings, safety and relief valves, pressure gauges and switches, auto-drain traps and fusible plugs — the complete starting-air system, not just the compressor.
Yes. We supply spares for Bauer and similar high-pressure breathing-air and charging compressors — filter cartridges, valves, piston rings and seals for Verticus, K14, K22 and BK series units used for SCBA and diving air.
Often, yes. Obsolete Sperre, Hatlapa and Tanabe models are exactly where the Alang reconditioning channel is strongest — valve plates, pistons and cylinders no longer made by the OEM can frequently be recovered, inspected and restored from recycled vessels.
