R1-R2-R3-R4-R4P
Designed for durability and flexibility, our compact models R1-R2-R3-R4-and R4P are ideal for high volume vacuum or compressed air applications. The most compact and lightweight of our motor mounted regenerative blowers, these models can operate as both a vacuum pump and an air compressor, efficiently creating high-pressure air or vacuum. These rugged models feature designs with corrosion-resistant materials and oil-free operation, and no wearing components, ensuring reliable performance and a clean, contaminant-free environment.
These models are available in a standard motor mounted option with sealed ball bearings with polyurea grease, and integrated mufflers for noise reduction as well as options with explosion-proof motors, thermal protection, double sealed ball bearings.
The models R1-R2-R3-R4-and R4P are perfect for a number of demanding blower applications in manufacturing, food and beverage, aquaculture, and chemical processing industries for applications like pneumatic conveying, aeration, and chemical transfer.
Find your perfect fit below.
Highlights
- Thermal Protection: The thermal over load protection protects motor windings from damage should the pump become stalled during operation
- Standard Motor Mounted Models: UL and CSA approved motors with sealed ball bearings with polyurea grease, and integrated mufflers for noise reduction
