Overview

The AERIS-P is a medium-pressure, single-inlet centrifugal fan designed for conveying clean or slightly dusty air in industrial and HVAC applications. The unit features a steel sheet casing and a backward-curved impeller, built for continuous operation and easy integration into process and ventilation systems.

Key design features

• System 4 configuration: impeller mounted directly on the motor shaft; motor supported on a rigid base frame to maintain permanent alignment and maximise power transmission.
• Backward-curved (reaction) impeller with self-cleaning profile; statically and dynamically balanced for quiet, efficient operation.
• Front support foot supplied to minimise vibrations (optional up to size 500; standard from size 560).
• Drive orientation adjustable on site up to size 630; sizes 710–1000 have factory-set orientation to ensure assembly integrity.

Applications

• Air intake and conveyance of clean/slightly dusty air
• Local exhaust and extraction
• Paint booths
• Civil and industrial HVAC systems

Construction and materials

• Standard construction: carbon steel (all ferrous parts in steel sheet).
• Up to size 630: high-precision lock-seam construction.
• From size 630: continuous welded construction for increased structural rigidity.
• Standard finish: industrial paint suitable for non-aggressive environments.

Thermal and special executions

• Standard execution suitable for continuous handling of air up to 130 °C.
• High-temperature executions available with cooling impeller, selected materials and construction adaptations enabling continuous operation up to 250 °C.
• Special executions available: inspection doors, drain plugs, sealed housings, thermal insulation, anti-spark designs and ATEX motor options.

Customization options

• Special materials: Stainless steel (AISI 304 / 316), Corten, Hardox for abrasion resistance.
• Surface protection: heat-resistant paint, hot-dip galvanizing, C4 / C5 coatings for saline or aggressive environments.
• Other options: high-temperature versions, inspection doors, drain plugs, sealed housings, thermal insulation, anti-spark designs, ATEX-certified motors.

Motorization and efficiency

• Equipped with TEFC (totally enclosed fan-cooled) motors suitable for demanding industrial environments.
• ErP compliance: IE2 for below 0.75 kW; IE3 standard from 0.75 kW to 55 kW; IE4 available from 75 kW upwards.
