Blowers and Fans - An Overview
Most manufacturing plants use fans and blowers for ventilation and for industrial processes that need an air flow (or any other gas, for example Biogas or Bio Gas). Fan systems are essential to keep manufacturing processes working, and consist of a fan, an electric motor, a drive system, ducts or piping, flow control devices, and air conditioning equipment (filters, cooling coils, heat exchangers, etc.).
The US Department of Energy estimates that 15 percent of electricity in the US manufacturing industry is used by motors. Similarly, in the commercial sector, electricity needed to operate fan motors composes a large portion of the energy costs for space conditioning.
Fans, blowers and compressors are differentiated by the method used to move the air, and by the system pressure they must operate against. The American Society of Mechanical Engineers (ASME) uses the specific ratio, which is the ratio of the discharge pressure over the suction pressure, to define fans, blowers and compressors.
At TMC Fluid Systems, we specialize in the manufacturing, design, and supply of Blower and Compressors capable of delivering Pressure Systems up to 14-PSI and higher when required.
See chart below:
|Blowers||1.11 to 1.20||1,136 to 2,066||1.6 to 3.0|
|Compressors||> 1.20||< 10,000||<14.0|
For more information, select from one of the following:
- Aqua-Series Blower: Typically used for Aeration offering 100% Oil Free Air Delivery. These blowers are also used in Aquaculture/Fish Farming and Hydroponics industry.
- Biogas Blower: Special design of Biogas (Bio Gas) Blowers used to either convey or boost the pressure of Biogas. Also used with Specialty Gases such as Natural Gas.
- Centrifugal Blower: Centrifugal Blowers are constant flow blowers and when operated at a constant speed will supply a constant volume of air.
- Regenerative Blowers:Regenerative Blowers are machines that move air by way of a non-positive displacement. The method by which regenerative blowers move the air, however, allows some air passing over a blade of the impeller to slip past it. This air is moved forward by another blade.
- Tri-Lobe Blowers: Tri-Lobe Blowers are Rotary Air Blowers that have three lobe tips exposed at 120o around the rotor.
- Turbo Blowers: Turbo Blowers are a fairly new introduction to the traditional faqmily of blowers and fans. They are capable of delivering larger flow rates at higher differential pressures,
- Twin-Lobe Blowers: Twin-Lobe Blowers are also Rotary Air Blowers that have two lobe tips exposed at 180o around the rotor.
- Water-Cooled Blowers: Water-Cooled Blowers are High Pressure Blowers capable of achieving Differential Pressures of up to 14-PSIG
