Powerful and quiet, the EP10A compact blower is one of ACI’s most versatile air movement products. Available with motors (5.5 to 18.5kW) in standard metric or NEMA frames, the EP10A can be easily retrofitted in place of other alternatives.

ACI offers two series of belt-driven blowers – the EP10A and the EP10AH (Hot Air Version).

EP10A Compact Blower
  • Flow rates up to 2040m³/hr
  • Pressures up to 250mBar
  • 5.5kW to 18.5kW
  • 60°C (140°F) maximum inlet temperature
  • Reliable, maintenance-free operation


EP10AH Compact Blower
  • Flow rates up to 2040m³/hr
  • Pressures up to 250mBar
  • 5.5kW to 18.5kW
  • 185°C (330°F) maximum inlet temperature
  • Reliable, maintenance-free operation
Both blower types feature:
  • State of the art impeller design and improved belt design producing less friction
  • Lower belt tension giving less bearing loads, resulting in longer service life
  • Uses steel bearing liners and precision hybrid ceramic sealed bearings
  • Quiet operation: precision manufacturing reduces all vibration & noise
  • No separate belt-tensioning wheel

More efficient & reliable than its competitors:


The EP10A blower head is cast and machined as a single piece with equally spaced bearings configured specifically to provide even loading from the belt drive. This design is fundamentally different from other belt driven units and allows the belt to be run at a tension much lower than other belt driven units, therefore resulting in much lower loads on all parts of the assembly.


The single piece construction also guarantees correct alignment of the integrated precision spindle. The outcome is a more robust and efficient assembly, which both improves manufacture and enhances stability and reliability, essential with operating speeds up to 20,000 rpm and deliveries of 1200 CFM.


Also contributing to the EP10’s durability are the specially engineered hybrid ceramic bearings that are sealed for life to prevent ingress of contaminant and retain the high-performance grease.


In addition, each EP10A spindle is assembled in a clean-room environment, away from the general factory. A vigorous 3 hour running in cycle is performed on each EP10A head, to ensure the bearing grease is distributed correctly. Once fully assembled, each EP10A blower is operated at full speed after final assembly.
