Airtech Vacuum 3BA1900-7AT06 Vacuum Pressure Regenerative Blower

Airtech 3BA1900-7AT06 Vacuum/Pressure Regenerative Blower is a single-stage, oil-free regenerative blower that can operate as a vacuum pump or a compressor, housed in rugged die-cast aluminum with an outboard bearing for maintenance-free operation. In 50 Hz service it is rated at 10.72 HP with 200–240 V delta or 345–415 V wye configuration; in 60 Hz service it delivers 12.06 HP with 220–250 V delta or 415–460 V wye, reflecting compatibility with common power systems. The TEFC motor is Class F insulated, UL recognized, and CE compliant, with explosion‑proof options available for higher‑risk environments. The unit weighs about 265 lb and is designed for cooler operation and long life. Performance figures show a maximum vacuum of −76 inH2O and a maximum compressor pressure of 76 inH2O at 50 Hz (sound level ~74 dB(A)); at 60 Hz, vacuum is −60 inH2O and compressor pressure 56 inH2O with a sound level around 79 dB(A). Filtration and relief provisions support vacuum and pressure service (vacuum filter ATF-400-21138, pressure filter AFS-234-400-10; vacuum relief VC100Z, pressure relief PC100Z), enabling integration into industrial processes such as material handling, pneumatic conveying, filtration, and packaging where reliable high‑pressure regeneration or recovery is required.
