Single-stage air vacuum blower R7100A-3

Description The 1-stage motor-mounted R7100A-3 is a 10 HP regenerative blower engineered for high-volume vacuum and compressed-air applications. Oil-free and built with corrosion‑resistant aluminum components, it provides contaminant-free pressure or vacuum. The unit operates at 190-220/380-415 V AC (50 Hz) and delivers a maximum continuous pressure of 125 in. H2O with open flow up to 425 CFM.

Highlights

• Thermal protection: Thermal overload protection to safeguard motor windings in stall conditions.
• Standard motor-mounted models: UL and CSA approved motors with sealed ball bearings (polyurea grease) and integrated mufflers for noise reduction.
• Explosion‑proof motor series (option): UL/CSA explosion‑proof motors with thermal protection, double‑sealed ball bearings (B10 life > 30,000 hours) and leak‑tested sealed air streams < 5 cc/min.
• Corrosion‑resistant components: Aluminum blower housing, impeller and cover to extend service life and uptime.

Applications

• Pneumatic conveying
• Aeration and aquaculture
• Chemical processing and transfer
• Industrial vacuum and compressed-air systems
