The VW3AE0922 is an air conditioning accessory for the Altivar 61 Plus and Altivar 71 Plus drive series, designed specifically for floor-standing enclosures with separate air flows or compact versions. It's not a general-purpose cooler — it's sized and ducted for the airflow path of those specific cabinets.
Sourcing and fit decision
Because this is an obsolete enclosure accessory — not a generic fan or filter — the fit is specific to the Altivar 61 Plus / 71 Plus floor-standing cabinet. If you're replacing a failed unit or filling a BOM line for a legacy drive installation, confirm the enclosure variant (separate air flows vs. compact) against the original cabinet drawing before committing the order.
