Axial Centrifugal ATEX Bi-Furcated In-Line Fans

R&B Industrial supply an extensive range of industrial fans for ventilation systems and air movement. Many fans are in stock available for next day delivery and at competitive prices. High efficiency low cost fans can be supplied for inverter control, enabling the most energy efficient operation, with maximum life cycle cost savings.

We have supplied and installed a vast array of fans ranging from:

  • centrifugal; 0.37 kW – 110 kW
  • Axial and bi-furcated,
  • Hi pressure fans – routes and side channel blowers
  • Plastic and GRP fans in axial and centrifugal ranges.
  • A whole range of ATEX fans for both explosive gas and dust applications, even for the most hazardous zone 0 flammable environments.
  • FA003 PADDLE BLADE BOOSTER FAN FOR WOODDUST
  • centrifugal fan02
  • Plastic fan types (2)
  • Plastic fan types (1)

The cost of running a fan can be as much as 100 times its initial cost. It is therefore imperative to look at the whole of life cost. The data below shows the costs of just an additional 1 kW on a motor, based on 24/7 operation, with inflation etc.

The cost of 1 Kw of energy over 1 year will be    :- £619
The cost of 1 kW of energy over 5 years will be   :- £3562
The cost of 1 kW of energy over 10 years will be :- £8558
The cost of 1 kW of energy over 20 years will be :- £25392
The cost of 1 kW of energy over 40 years will be :- £123653

The above figures show how important it is to focus on energy efficiency; a slightly more expensive fan which is more energy efficient can provide considerable cost savings over a relatively short timescale ie 1 – 2 years. Even though the initial cost of the fan may be slightly more expensive.

This above figures are based on the following assumptions :-

  • Electricity Costs at normal rate (between hours 07:00 to 12:00am) of £0.079 / kW Hour
  • Electricity Costs at Redued rate (between hours 00:00 to 07:00) of £0.056 / kW Hour
  • 24 hours / day, 7 days / week and 51 weeks / year.
  • Annual Energy Inflation rate of 1.07 (ie 7%), at this inflation rate energy costs double every 11 years.

(We have used historical electricity prices over the last 20 years to establish the inflation rate above. )

  • The inflation rate is obviously a variable, but energy prices are generally on the increase.

Our fans are in general sized for most energy efficient performance, and are fitted with motors conforming to the latest International standard IEC 60034-30:2008 defining new energy efficiency classes for electric motors.

Under the European Directive, the IE system, for motor efficiency, will be implemented in phases, gradually replacing the Eff scheme. From June 2011 the intention is to require all motors placed on the market that fall within the scope of IEC 60034-30 to be at least IE2. From January 2015, motors rated from 7.5 to 375 kW will have to be IE3 or be IE2 and installed with a variable-speed drive. The same requirement will be extended to motors in the range 0.75 to 7.5 kW from 2017

IE2 = High efficiency (with efficiency levels similar to the existing CEMEP Eff1 class)

We can supply and install motor starters including; DOL, STAR DELTA, SOFT START, and INVERTER (variable speed drives VSD) to meet specific requirements.

VSD’s can provide major energy/cost savings, when designed with automatic control via a range of options including: Constant Volume / velocity Control, Constant or differential pressure, cascade or ratio control please see Motor Starters, Control panels, automation and monitoring systems. We also provide control tuning and commissioning of installed systems.

We also have a number of 2nd hand fans available – please contact for details.

Acoustic Enclosures and Jackets are available for virtually all fans for noise reduction see Noise Attenuation and Control images\Acoustic fans

Plastic Fans

Plastic fans can be supplied for hazardous gas / fume extraction; including acid, alkali, methylene chloride gas/fume streams etc.: Manufactured for the specific application and design ie centrifugal, bi-furcated, in-line axial,
