HOFFMAN's REVOLUTIONPLUS 400-700HP models are manufactured with a dual impeller/twin motor and are water jacket cooled. The models within this range of our Series are built using a high-performance permanent magnet synchronous motor (PMSM) to increase operational efficiency.
Hoffman's high-speed 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, HOFFMAN’s 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 performance window and range of the unit vary depending on the flow/pressure combination, job site conditions, and the application itself.
HOFFMAN's REVOLUTIONPLUS high-speed turbo blowers stands out amongst other manufacturers because of our advanced design and patented air bearing and coating technology. High-speed turbo blowers have permanent magnet synchronous motors (PMSM). These 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 PMSM motor’s operating speed to meet operational requirements. This allows operators to tailor their high-speed blower's performance to meet oxygen demand, further increasing the levels of efficiency.
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.
High-speed turbo blower technology delivers maximum performance by packaging a single-stage centrifugal blower with advanced energy management systems. The combination provides an efficient package designed to deliver superior efficiency for wastewater and general industrial applications.
Simple Maintenance.
Provides energy savings of up to 40% and a significantly reduced carbon footprint.
Constructed to mitigate noise pollution <85 dBA sound rating.
Compact design requires no special foundation support due to leveling feet. The blower can operate separately from the controller, up to 100 feet maximum.
Access panels to electronics and air-end equipped with gasket material to protect from damage caused by exterior dirt and debris.
Our patented air foil bearing technology reduces heat loss in the motor and improves total efficiency.
