Rietschle DTN 40 Replacement Carbon Vanes – 518943

ELMO RIETSCHLE DTN 40 REPLACEMENT CARBON VANES

VacAir Superstore supplies Rietschle DTN 40 replacement carbon vanes from UK stock. We sell the 518943 carbon vane to industrial maintenance teams, compressor service engineers and purchasing departments responsible for keeping dry-running rotary vane equipment operational.

The DTN 40 compressor has a seven-vane rotor arrangement. Each new carbon vane measures 85 × 47 × 4 mm and moves within its rotor slot during operation. Wear is a normal part of the vane’s working life, but the remaining carbon height and general condition should be assessed at appropriate maintenance intervals.

For the DTN 40, the minimum permitted vane height is 35 mm, compared with the original height of 47 mm. Measuring all seven vanes provides a clearer picture of the compressor’s condition than checking only the most accessible components. A vane that is cracked, chipped or wearing differently from the others may require attention even before reaching the dimensional limit.

The 518943 vane is used in several Elmo Rietschle vacuum pumps and compressors. However, the number of vanes required is not universal. The DTN 40 takes seven, as do models such as the DTN 41, KTN 40 and VTN 40, while the TR 40D uses six. This makes the compressor model and set quantity just as important as the OEM number when ordering replacement components.

VacAir also supports customers with Elmo Rietschle spare parts and filters, as well as professional vane fitting and compressor servicing where further assistance is required.

DTN 40 VANE FITTING & PUMP SERVICING

For a DTN 40 compressor, vane replacement provides an opportunity to assess the condition of the entire seven-slot rotor assembly. The objective is not simply to install fresh carbon but to establish that the internal components are suitable for continued operation.

Each new 518943 vane measures 85 × 47 × 4 mm, with an original height of 47 mm. The minimum permitted height for the DTN 40 is 35 mm. Measuring all seven removed vanes and comparing their condition can help identify whether wear has occurred evenly or whether one area of the rotor requires closer examination.

Before maintenance, isolate the compressor safely and follow the relevant manufacturer’s service procedure. With the rotor assembly accessible, inspect each slot for deposits, damage and restricted movement. Examine the cylinder running surface for scoring and check for carbon fragments, particularly if a vane has fractured.

Bearing condition, rotor alignment and filtration should also be considered where the existing vanes show unusual wear. A replacement set may not resolve a fault caused by mechanical damage or contamination, so any underlying problem should be addressed before the compressor is returned to service.

When replacement is required, fit seven matching 518943 carbon vanes in accordance with the manufacturer’s fitting instructions. VacAir supplies these components to customers carrying out their own maintenance. Our OEM-trained engineers can also assist with professional vane fitting, compressor fault investigation, servicing and repairs.

Our customers include manufacturers, OEMs, maintenance contractors, distributors and engineering businesses that need dependable access to the correct parts. We understand that a compressor service can depend on something as straightforward as having the right carbon vanes available when they are needed.

DTN 40 replacement vanes stocked in the UK. We stock Rietschle 518943 carbon vanes, manufactured to the 85 × 47 × 4 mm specification. The DTN 40 requires seven vanes.

That attention to detail is particularly valuable when a compressor has already been dismantled for maintenance.

Specialist knowledge of dry-running rotary vane machinery. VacAir is not simply a general catalogue supplier listing industrial components. We work with vacuum pumps, compressors, replacement vanes, filtration and engineering services. For the DTN 40, the 35 mm minimum permitted vane height provides an important inspection reference against the original 47 mm. Our team also understands the significance of cracked carbon, restricted rotor slots, scoring and other signs that a compressor may need attention beyond fitting new vanes.

Competitive prices supported by our Price Promise. We aim to offer excellent value on replacement carbon vanes while retaining the advantages of buying from an experienced industrial specialist. Our published Price Promise explains the conditions under which qualifying like-for-like UK competitor prices may be matched. Customers can raise a comparison when requesting a quotation.
