Minimise the introduction, generation and retention of dust and particles with
Fans for Containment & Cleanroom Ventilation Systems
Efficient EC plug fans provide the necessary pressure and airflow to adhere to the strict environment of cleanroom, containment and isolation applications. Air management and maintaining a constant air pressure using properly specified industrial fans are key aspects of providing a safe and healthy environment in cleanrooms. Cleanrooms are contained rooms with highly efficient fan filter units built into the ceiling and connected to the building ventilation system, that vacuum the air particles in the room through a set of HEPA filters. This highly precise ventilation system controls the temperature, maintains a constant air pressure and continuously cleans and filters the air to eliminate contaminants protecting staff from exposure to highly potent pharmaceutical ingredients whilst also ensuring a clean uncontaminated procedure in the case of processing.
The Importance of Accurate Fan Selection in Sensitive Applications
Effective cleanroom ventilation systems provide better containment of active ingredients ensuring medicinal products are packaged in pristine condition. As the development of new strengths of medication grows so does the need to safeguard staff working in these environments. Some pharmaceutical powders can be highly potent and therefore cleanroom designers in this sector have strict guidelines to follow to eliminate exposure. It is important that all personal using these rooms know how to clean the room, change air filters and monitor the air flow of the room.
High pressure, energy efficient plug fans, meticulously designed to
Maintain Pressure in Fan Filter Units
Pharmaceutical cleanrooms require three or four stages of HEPA filters and therefore need high pressure backward curved plug fans such as the G-Wheel EC plug fans. High performance ventilation systems ensure consistent clean air with a high air exchange rate and the correct measure of pressure, temperature and humidity. Even the smallest contaminated particle can affect product manufacturing such as powder control, so it is vital that companies are complaint, with good manufacturing practices and adhere to the classification guidelines. System and industrial plug fan specification is determined by taking into account the individual characteristics of each cleanroom set up, including the number of contaminants that are likely to be produced, the size of the particles that need to be filtered and the airflow and pressure required to remove and purify the air. The size of the room will depend on the equipment needed and the number of processes required. A fan filter unit for containment serves to generate a uniform, particle free airflow in the clean room. FFU’s allow smaller air handling units to be specified for a particular cleanroom installation, saving time and cost.
High Pressure, Noise Attenuated EC Plug Fans
The technology behind fan filter units is simply a HEPA filter attached to an EC Plug Fan, offering highly efficient filtration to cleanrooms. Our energy efficient plug fans enable more compact air handling. G wheel fans generate the required airflow while working against the increasing resistances of filters to deliver a constant volume of air. The on board controls allow the user to program the exact airflow and pressure requirements, while a sensor works to constantly monitor the output, adjusting accordingly.
With reductions in operating noise, low running costs and high efficiency filtration that is easy to maintain, the fan maintains a clean, safe and cost effective space. Cleanrooms operate continuously and therefore tend to have high running costs so the initial capital outlay for incorporating energy efficient plug type fans is soon returned with the significant energy savings. The option of speed control allows for slowing down the fan filter unit when not in use to reduce power consumption, improving the life of the motor and filters.
Case Study: EC Fans in UK's Leading Powder Control Ventilation
Plug fans can be used in a variety of applications where noise and energy consumption are paramount such as computer room air conditioning and air handling, energy recovery ventilation, energy recovery units, box and roof fans. One case study to demonstrate the gains in a powder control booth application.
Due to the size of the room in a typical powder control booth, the customer required a high pressure, high airflow solution for their ventilation system. A typical operating duty of 3300m³h with 1200Pa maximum pressure per fan was required. The existing components were proving to be very noisy in operation and so an alternative was needed.
