The Story

⚠ SPECIAL ORDER ITEM — Extended Lead Times Apply

Effective July 1, 2026, Unico has discontinued regular production of ST2 blower units. ST2 units can still be built by Unico on request, but all orders are now treated as special-order items and may carry extended lead times. Replacement parts for ST2 units remain fully supported. The BL2-EC2 models are now the only blower units in Unico’s regular production offering — contact us if you’d like help selecting an equivalent BL2-EC2 unit or confirming lead time on an ST2 special order.
