We proudly represent Hoffman Lamson Multistage Centrifugal and High Turbo Blowers in Eastern Pennsylvania, Southern New Jersey, Maryland, Northern Virginia, Delaware, and DC.
Multistage centrifugal blowers are rotating machines able to increase the pressure of air or gasses through the centrifugal force normally transmitted by an electric motor.

Equipment is tested prior to reaching the customer or end-user. This ensures top quality and avoids unforeseeable issues or operational downtime. Therefore, upholding Hoffman & Lamson’s strong reputation as the global leader of engineered solutions and producing premier quality products efficiently and economically. There are over 100,000 HOFFMAN & LAMSON multistage centrifugal blowers and exhausters in operation worldwide.
Hoffman & Lamson high-speed turbo blowers combine an advanced blower management system with a significantly smaller footprint than traditional blowers to set a new standard for design, efficiency, and performance. HOFFMAN’s REVOLUTIONPLUS Series offers various turbo blower models with power inputs ranging from 10 to 700 horsepower, making them an ideal choice for a wide range of applications.
Our customers count on us to help them reduce their carbon footprint. Our REVOLUTIONPLUS models are designed with performance and operational benefits in mind. Each unit is engineered with dynamic balancing impellers and fitted with a compact and durable high-speed motor coupled with our patented air foil bearing technology. Combining these with other innovative design elements, Hoffman’s high-speed blowers provide increased reliability, require minimal maintenance, and deliver energy savings of up to 40%. HOFFMAN turbo blowers are factory prewired and tested in an ergonomic sound enclosure for plug-and-play operation.
HOFFMAN’s REVOLUTIONPLUS turbo blowers consist of a compression unit equipped with a blow-off valve that releases air, protecting the unit during start/stop, while an inverter controls the rotating speed of the blower’s high-speed motor. Housed in a robust, sound-insulated enclosure, the REVOLUTIONPLUS series features a Programmable Logic Controller (PLC); allowing operators to actively monitor, control, and adjust the speed to meet changing process demands and operating conditions.
The high-speed motors within a REVOLUTIONPLUS turbo blower provide a much higher operational velocity, output, and performance than traditional induction motors. All HOFFMAN high-speed turbo blowers are fitted with a VSD (variable speed drive) as standard. The VSD adjusts the motor’s operating speed to meet operational requirements. These features allow operators to tailor the performance to meet oxygen demand, further increasing the levels of efficiency that they can provide.
Advanced Impeller and Air Foil Bearing Design Increases Turbo Blower Performance
HOFFMAN’s REVOLUTIONPLUS Series of high-speed turbo blowers stands out amongst other manufacturers because of our advanced design and patented air bearing design and coating technology. Impellers are available in various designs including cast, fabricated, and moulded. Impellers are critical to the performance of any high-speed blower, so Hoffman utilizes single block machined aluminum across the range with pitch and blade variations for different pressure requirements. Our multi-foil air bearing design allows for tighter tolerances which increases the stability in a wider range of rotational speeds. The superior construction of the bearing material, including heat treatment and a Teflon coating, acts as a suspension that improves the damping capability by 30% compared to the single foil designs seen on other high-speed blowers available in the market.
