How to Save Energy with Fan Speed Control

Speed control is often overlooked when specifying fans, however significant savings can be had by the use of the correct speed controller and fan combination. These are not just direct savings in energy consumed by the fans but indirect savings from ancillary equipment. The addition of a fan speed controller can add extra functionality to products enhancing their usability and safety. It is often desirable where applications have varying output requirements, and control of the motor speed is more efficient than mechanically limiting the proc...

Commercial Kitchen Extractor Fans & Supply Air Fans

Meeting the Demands of a Commercial Kitchen Commercial kitchens demand high quality extraction and exhaust fans to withstand the rigours of continuous contact with hot, greasy air. In such environments, air change is supplied by a mechanical ventilation system. This is usually via an extract canopy situated above the appliances that is exhausted via a roof fan or horizontally through ducting. Sufficient outdoor air must be provided through supply fans to replace the extract air to avoid creating a vacuum. Therefore, a combination of supply air...


Filter Fans: What is the difference between the FF & FPF?

The re-engineered FF series of filter fans offers an innovative easy-to-mount solution that requires no tools thanks to a simple click-fit design. Due to its enhanced construction, the FF considerably reduces the risk of water infiltration and increases operational safety. We explain the key differences between the FF series and the original FPF series of filter fans below. Click-fit rapid installation with mounting clips Innovative new mounting clips have been added to the FF series to allow for fast, tool-free installation. No screws are n...

Wastewater Treatment Ventilation: Polypropylene vs. Stainless Steel and GRP

Wastewater treatment plants face a number of challenges in terms of ensuring safe and effective ventilation. The chemicals used during the wastewater treatment process pass through metering equipment in a dosing system. In the system, the solution is at its strongest and the chemicals and their gases are often corrosive and can be flammable. Such chemicals and gases include methane, ammonia, phosphorous, pesticides and carbon dioxide. Consequently, wastewater treatment plants are, by their nature, one of the harshest engineering environments. ...

Avoiding Corrosion in HVAC & Protecting Employee Health

When installing a HVAC system, the main aim is usually to heat or cool the environment for employee comfort. Often underestimated is the impact that HVAC systems can have on employee health. Corrosion, caused by the presence of chemicals, is one of the biggest threats to HVAC systems and indicates an unsafe environment for employees. Corrosion damage and its consequences in HVAC systems are discussed below. What is Corrosion Damage? Corrosion mainly occurs in metals when they react with their environments; their refined form turns into stable...


Renewable Energy: Fans for Wind Turbines

The UK's offshore wind power capacity is set to nearly double by 2030, as a result of a new government initiative. Offshore wind has become an increasingly affordable source of clean energy due to plummeting costs. This, coupled with an increasing environmental awareness in consumers, is reinvigorating the focus on wind as a source of inexpensive, renewable energy. Wind turbines require fans to ventilate and cool several different areas to maintain and preserve the functioning of its equipment. These areas include the nacelle, generator, tra...
