Nicotra Gebhardt RDH 560 Alternative — LONGWELL RDH-R 560
Looking for an alternative to Nicotra Gebhardt RDH 560? LONGWELL's commercial centrifugal line mirrors the Nicotra naming 1:1 — RDH-R 560 — with identical frame designation, dimensional interchangeability, belt-drive or factory EC-upgrade, AMCA-tested aerodynamics, at 40–55% lower landed cost and 15-day delivery vs 10–14 weeks ex-works Nicotra. This is the single highest-value naming-mirror battle in the commercial AHU segment.

Frame & dimensional match
LONGWELL RDH-R 560 carries the identical backward-inclined frame designation as Nicotra RDH 560 — scroll dimensions, inlet cone, outlet flange, and shaft/bearing centres match 1:1, so it drops into the same AHU section, the same belt-guard, and the same pedestal without rework.
Drive & motor options
LONGWELL ships the RDH-R 560 belt-driven with a selectable IE3 / IE4 motor to match the existing Nicotra RDH 560 drive train, and offers a factory EC-upgrade variant (the -K suffix) that replaces the belt with a direct EC drive for variable-volume AHU and 25–40% fan energy savings.
Performance match
The aerodynamic curve of LONGWELL RDH-R 560 tracks the Nicotra RDH 560 within AMCA 210 test tolerance across the operating envelope (third-party tested). RDH-R 560 → Nicotra RDH 560 (30,000 m³/h, 2,200 Pa); RDH-R 450 → RDH 450 (18,000 m³/h, 1,800 Pa). Full RDH-R range covers 280–630. Performance is matched at the published duty point, with LONGWELL's documented cross-brand library backing the selection.
Typical Applications
The LONGWELL RDH-R 560 is widely deployed across high-pressure industrial AHU and process ventilation. Common application categories include:
- High-pressure industrial AHU
- Process & dust extraction
- Library / archive HVAC
RDH is the high-static backward-inclined workhorse; LONGWELL RDH-R 560 / 450 mirror it 1:1 for high-resistance systems.
