R4P315A

Our 1-stage small motor-mounted R4P315A is built for durability making it ideal for high-volume vacuum or compressed air applications. Engineered oil-free with corrosion resistant materials, this single phase regenerative blower delivers reliable, contaminant-free pressure or vacuum efficiently. The 1 1/2 HP R4P315A operates at 190-220/380-415V AC with maximum continuous pressure of 63 in. H2O and air flow of 127 CFM.

Designed for durability and flexibility, models R4-RP4 are ideal for high-volume vacuum or compressed air applications. The most compact and lightweight in our motor-mounted regenerative blower series, these models operate as both vacuum pumps and air compressors-efficiently generating high-pressure air or vacuum. With corrosion-resistant materials, oil-free operation, and no wearing components, they deliver reliable, contaminant-free performance.
Available in standard motor-mounted configurations with sealed ball bearings and integrated mufflers for noise reduction, these models also offer options like explosion-proof motors, thermal protection, and double-sealed bearings.
R4-RP4 are perfect for demanding blower applications in manufacturing, food and beverage, aquaculture, and chemical processing – supporting pneumatic conveying, aeration, and chemical transfer.
