Comefri NPA630RD Centrifugal fan

• Industrial ventilation systems for factories and warehouses.
• Fume extraction in workshops and manufacturing facilities.
• Air handling units for commercial buildings.
• Drying processes in various industries.
• Material conveying in light industrial applications.

Fan Type

Centrifugal, typically suitable for moving air against significant static pressure.

Impeller Diameter

For a model designation like NPA630RD, the impeller diameter is typically around 630mm.

Motor Power

This unit is listed with a 7.5kW motor, which is common for this size of industrial centrifugal fan.

Airflow Capacity

Typically, units of this class can move several thousand cubic meters per hour, depending on static pressure requirements.

Static Pressure

Centrifugal fans are designed to generate higher static pressures compared to axial fans, commonly ranging from a few hundred to several thousand Pascals.

Construction Material

Casings and impellers are commonly constructed from mild steel, with options for stainless steel or other materials depending on application.

Drive Type

Typically direct drive or belt-driven, with the latter offering flexibility in speed adjustment.

Noise Level

Industrial centrifugal fans commonly operate at noise levels requiring consideration for workplace acoustics, often above 80 dB(A) without attenuation.

• What is the difference between a centrifugal and an axial fan?

  Centrifugal fans move air radially, generating higher static pressure suitable for ducted systems. Axial fans move air parallel to the impeller axis, ideal for high airflow at lower static pressures.

• Can this fan be used for corrosive environments?

• What kind of maintenance does a centrifugal fan require?

• Is a variable speed drive (VSD) compatible with this fan?

• What is the typical lifespan of a used industrial fan?

• How do I determine if this fan is suitable for my existing ductwork?

HVAC drives and controllers are valued for reliable temperature and humidity regulation in controlled laboratory environments. Buyers typically prioritise units with precise calibration history and minimal downtime records. When purchasing used equipment, inspecting control boards, sensor functionality and documentation of maintenance schedules proves essential. These systems gain strong reputation for durability when properly serviced, though older models may lack advanced digital interfaces. Compatibility with existing facility infrastructure remains a common purchasing consideration.
