DC Centrifugal Fans / Blowers - MBD Series

DC Centrifugal Fans / Blowers - MBD Series

The MBD Series DC input centrifugal blowers provide large static pressure and can produce directional air flow ideal for cooling, drying or forcing air through duct work. Low Speed Alarm type fans are available.

Available in 3 frame sizes from 3.15 in. (80 mm) to 6.30 in (160 mm) with a maximum air flow of 106 CFM (3.0 m3/min) and a maximum static pressure of 1.49 inH2O (372 Pa).

  • Provide High Static Pressure and Directional Air Flow
  • 24 VDC or 48 VDC
  • Low Speed Alarm types available
  • Fan Kits available

AC Centrifugal Fans / Blowers

Centrifugal Fans / Blowers

Centrifugal blowers move air by means of the centrifugal force generated by rotating a cylindrical runner on which blades have been arranged. Centrifugal blowers have a small outlet, which concentrates air in a single direction and are therefore suitable for local cooling. They also create large static pressure, making them optimal for cooling equipment through which air cannot flow easily and for airflow through ducts.

Centrifugal Fan / Blower

Cooling with High Static Pressure

The high static pressure of centrifugal blowers makes them suitable for cooling used together with thick filters that are subject to significant pressure losses.

High Static Pressure

Air-Blow Cooling or Drying

Centrifugal blowers offering high static pressures are suitable for the air-blow cooling of work pieces following a heat treatment.

Low Speed Alarm Type

An alarm is output when the fan speed drops due to the service life of the fan or ingress of foreign objects. This makes it possible to order and replace the fan with a new one before it stops.

If multiple cooling fans are being used, it is possible to only replace the cooling fan with decreased cooling capacity. Even if the cooling capacity of the fan decreases, the effect on the equipment can be minimized.

Low Speed Alarm

Fan Kits Available

Various accessories will help you improve the safety and utility of fans. We recommend our fan kits, which combine the fan and necessary accessories in a convenient package.

Example:


Thermostat Available for Energy Saving

Thermostats (sold separately) make it possible for fans to operate only when cooling is necessary. Thermostats provide energy-saving by automatically stopping fans for example, at night, when the amount of heat generation declines following the load rate's decline in equipment, or in winter, when the ambient temperature drops and forced cooling is not necessary.



Thermostat

Thermostat

Thermostats automatically perform ON/OFF fan control in accordance with the temperature fluctuation inside the equipment. It helps improve the equipment's "environmental" performance relative to energy savings, noise reduction, etc.

Filters

Filter

When using a fan to cool machinery, dust may accumulate inside the machinery after long periods of operation. Depending on the parts involved, this could cause a malfunction. These filters prevent dust from entering the device, keeping the air inside the machinery dust free.
