EC Plug Fans for Powder Control & Clean Room Applications

Ventilation & Energy Efficiency are the key areas to consider when designing a cleanroom for powder control. Clean rooms are vital when it comes to ensuring powdered medicines are contamination free during and after the manufacturing and packaging stages. Investing in new technology in addition to adopting hygienic handling techniques are paramount to effective clean rooms. Not forgetting air ducts and ventilation areas to facilitate the airflow and pressure required to ensure the required number of air changes per house and pressurisation of contaminants. Designers must dedicate time to designing clean rooms and the equipment located within them. Downdraft benches with highly efficient HEPA filters are used to prevent users being exposed to strong, active ingredients during handling. Contaminated air is trapped in the filters and clean filtered air circulates back into the room. Personnel have a duty of care to comply with the regulations when operating inside cleanrooms and must complete the necessary training beforehand.


Modern clean room designs use computer aided engineering programs such as Building Information Modelling (BIM) software. Recent advances in construction ensure that clean rooms are built to a higher standard in terms of reducing contamination and exposure risks. Advances in micro-computing also allow the motors and fans that drive clean room air conditioning system to be self-adjusting, whereby the airflow adjusts in relation to changes in pressure.

There have been a number of global initiatives around energy efficiency in clean rooms, such as the BS EN 16001 standard. As stated on Cleanroom Technology the BS EN 16001 is the energy management standard that demands a greener ethos and yet puts commercial performance on the front line. It is a guide for cleanroom users to look at how they manage their energy usage and provides commercial benefits in terms of reduction in operational costs. Advances in micro-computing also allow the motors and fans that drive clean room air conditioning system to be self adjusting, whereby the airflow adjusts in relation to changes in pressure.

EC Plug Fans for Cleanroom Applications


The highly efficient E-Wheel from Axair fans can be used to facilitate effective ventilation systems within powder control booths and clean rooms either in a fan filter unit (FFU) or other ventilation systems. Available in five sizes, the E-Wheel has impressive efficiencies and key features when compared with competitor alternatives. In powder control rooms, legislation refers to noise levels per operator over a specified time period.


Recently Axair Fans was approached by a leading powder control booth manufacturer providing world class containment and infection control solutions.


GKHM EWheel EC PLug FansThe Problem: Noisy Ventilation

Due to the small size of the room given in any typical control booth or clean room, our customer required a high pressure, high airflow solution for their ventilation system. An operating duty of 300m3h with 1220Pa max pressure per fan was the required specification. The current components were proving noisy in operation and an alternative was needed quickly.

The Solution: Noise Optimised Ventilation

Fitting four backward curved centrifugal impellers, known as the E-Wheel from the E-Series in a modular plug type composition proved to be an efficient and effective solution. Producing a significant reduction in operation noise and achieved the required duty with ease. The E-wheel produces cost effective savings for our customer by consuming less power in operation.

Why The E-Wheel backward curved centrifugal fan?

The re-profiled blades and diffuser wheel of the E-Wheel make it a cost effective line when compare with leading competitor products. Cost effective materials and a focused design produce less vibration, significantly reducing the noise levels and subsequently using less power to make a cost effective and energy efficient ventilation system.

Other backward curved impellers can be used effectively across cleanroom and containment applications, including the aluminium B-Wheel or the Steel high pressure G-Wheel impeller.
