Air turbo-blower REVOLUTION PLUS

centrifugalimpellersingle-stage

Overview
HOFFMAN's REVOLUTIONPLUS high‑speed turbo blowers deliver compact, energy‑efficient single‑stage centrifugal compression for industrial processes. Units are factory pre‑wired and tested inside a sound‑insulated enclosure for straightforward plug‑and‑play deployment. The series combines a high‑speed PMSM motor with Class III anodized aluminum impellers and a patented multi‑foil air bearing with Teflon coating to extend service life and reduce maintenance needs.

Design and Operation
The compression airend incorporates a blow‑off valve to protect the air end during start/stop cycles. Motor speed is regulated by a Variable Speed Drive (VSD). A built‑in PLC provides monitoring, control and speed adjustment to match process demand. Actual performance depends on flow/pressure combinations, site conditions and specific applications.

Key Features and Benefits

• Dual impeller / twin motor arrangement for 400–700 HP models.
• Water‑jacket motor cooling for units in the 400–700 HP range.
• High‑performance Permanent Magnet Synchronous Motor (PMSM) for improved efficiency.
• Variable Speed Drive (VSD) standard to adapt blower speed to process/oxygen demand.
• Patented multi‑foil air bearing with Teflon coating for improved damping and stability (~30% better vs single‑foil designs).
• Impellers manufactured from Class III anodized aluminum.
• No belts, gears or oil required — simplified maintenance.
• Compact footprint with sound‑insulated enclosure and leveling feet; no special foundations required.
• Factory pre‑wired and tested for plug‑and‑play installation.
• Access panels and gasketed air‑end/electronics enclosures for protection against dirt and debris.
• Low‑noise design; sound level rating <85 dBA.
• Energy savings up to 40% and reduced carbon footprint compared with conventional solutions.
• Controller‑independent operation possible up to 100 ft (installation‑dependent).

Applications
Packaged and optimized for wastewater treatment and general industrial applications requiring efficient single‑stage centrifugal blower performance and advanced energy management.
