ELMO RIETSCHLE DTN 41 REPLACEMENT CARBON VANES
VacAir Superstore stocks Rietschle DTN 41 replacement carbon vanes for industrial compressor servicing and repairs. We supply the 518943 vane to engineers, production facilities and specialist maintenance businesses looking for correctly specified replacement carbon without the uncertainty of a general-purpose parts catalogue.
The DTN 41 is a dry-running rotary vane compressor using seven carbon vanes within its rotor. These sliding components are subject to gradual wear during normal operation. Each new vane measures 85 × 47 × 4 mm, and maintaining the correct vane condition is an important part of protecting the compressor’s internal running surfaces and sustaining dependable air delivery.
For this model, the minimum permitted vane height is 35 mm. Compared with the original 47 mm height, this provides a clear dimensional reference for servicing. All seven vanes should be measured individually, and any unusual wear pattern, fractured corner or cracked vane should be investigated rather than relying on height measurements alone.
The Rietschle 518943 part number is shared by several machines in the 40 and 41 series. The DTN 40 and DTN 41 both require seven vanes, but some TR-series models using the same individual component require only six. Identifying the precise compressor model therefore remains important when ordering a complete replacement quantity.
VacAir can also help with Rietschle spare parts and filters. Where a compressor needs more than a straightforward vane replacement, our engineering and repair services provide additional support.

RIETSCHLE DTN 41 VANE INSPECTION & REPLACEMENT
|
When inspecting a DTN 41 compressor, engineers should consider the remaining carbon height, the condition of the vane edges and whether the seven vanes have worn at a similar rate. Differences between rotor positions may provide useful evidence of a developing internal problem. The 518943 vane has an original height of 47 mm. The specified DTN 41 minimum permitted height is 35 mm. Measure each of the seven vanes and examine the carbon for cracks, chips, unusual polishing or irregular wear. A component showing physical damage may need replacing before it reaches the dimensional limit. DTN 41 maintenance inspection points: ✓ Record the height of all seven carbon vanes ✓ Check measurements against the 35 mm minimum ✓ Compare wear patterns between rotor positions ✓ Examine corners and edges for fractures ✓ Check rotor slots for restricted vane movement ✓ Remove accumulated carbon dust and debris ✓ Look for scoring on internal running surfaces ✓ Examine rotor and shaft condition ✓ Assess bearings for excessive movement ✓ Check inlet filtration and contamination DTN 41 wear reference: New vane height 47 mm; minimum permitted height 35 mm. A full replacement uses seven 518943 carbon vanes.

ELMO RIETSCHLE DTN 41 SPARE PARTS

VacAir stocks and sells Rietschle DTN 41 replacement carbon vanes under reference VA518943. These correspond to OEM part number 518943, also identified as 5189430000. Each vane measures 85 × 47 × 4 mm, and the DTN 41 requires seven for a complete replacement. An important consideration when ordering DTN 41 spares is the shared 518943 vane specification. The same component appears in numerous Rietschle compressor and vacuum pump models, including the DTN 40, KTN 41 and VTN 41. This commonality can be useful when maintaining a fleet of machines, but the complete model designation remains essential for confirming the quantity required. For example, a DTN 41 requires seven vanes, whereas certain Rietschle TR 40 and TR 41 configurations use six. Ordering by vane number alone may therefore produce the correct individual component but an incomplete or excessive quantity for the machine being serviced. During maintenance, associated components should be examined alongside the vanes. Inlet filtration, rotor slots, bearings and internal running surfaces may require attention, particularly where carbon fragments or unusual wear have been found. VacAir can assist with sourcing additional Rietschle spare parts and discussing the appropriate repair requirements. ✓ Rietschle 518943 replacement carbon vanes ✓ Seven matching vanes for the DTN 41 compressor ✓ Rietschle filters and maintenance spares ✓ Specialist assistance with parts identification |

DTN 41 VANE FITTING & PUMP SERVICING
The DTN 41’s seven carbon vanes should be considered as a complete working set during compressor maintenance. Their condition can reveal not only when replacement is necessary but also whether the rotor and internal surfaces have been operating correctly.
Each new 518943 vane measures 85 × 47 × 4 mm. The 47 mm original height should be compared with the DTN 41’s 35 mm minimum permitted height. Measuring every vane separately helps identify differences in wear that may not be obvious from a general visual inspection.
Before dismantling, isolate the compressor safely and follow the manufacturer’s service instructions. Inspect the rotor slots for accumulated carbon dust, debris or damage that could prevent free vane movement. Examine the cylinder running surface and rotor for scoring or other evidence of abnormal contact.
A fractured vane should prompt particular care. Carbon fragments can remain within the compressor, and damage to the surrounding components may have contributed to the original failure. Bearing condition, filtration and any signs of overheating should be assessed before installing replacement parts.
When a complete replacement is required, fit seven matching 518943 carbon vanes in accordance with the appropriate service procedure. VacAir supplies the replacement components to customers with their own maintenance resources, while our OEM-trained engineers can assist with fitting, fault diagnosis and compressor repairs where required.

Customers sourcing DTN 41 vanes benefit from dealing directly with an established industrial supplier.
Seven correctly specified DTN 41 vanes from UK stock. We stock Rietschle 518943 replacement carbon vanes, measuring 85 × 47 × 4 mm. The DTN 41 requires seven pieces. Although this individual vane is common to numerous Rietschle machines, not every model uses the same quantity. Our product identification information helps distinguish seven-vane DTN applications from six-vane TR configurations, reducing the risk of ordering an incomplete set.
Industrial compressor expertise rather than catalogue-only selling. Our knowledge covers dry-running rotary vane compressors, vacuum pumps, replacement vanes, filters and associated service components. For the DTN 41, we recognise the significance of the 35 mm minimum permitted vane height and the need to inspect all seven vanes for consistent wear. If a customer encounters damaged carbon, scoring or a restricted rotor slot, we can discuss the wider maintenance implications instead of treating the enquiry as a simple parts transaction.
