4 Types of Blowers to Consider for Your New Business
Blowers are common in industrial manufacturing, but with so many options, it can seem overwhelming, especially for new businesses. New business face a lot of challenges, especially financial challenges. Getting one wrong blower could waste a lot of money that could be allocated for other machines or services.
If you want to give your new business the best start, you need to understand which blowers you need. If you would like to know more, check out these four types of blowers to consider for your new business.
1. Rotary Lobe
Rotary lobe blowers are common for low pressure, and they
use two different rotors with two to three lobes. As the lobes rotate they pull
air through the inlet and then force
s it out through the discharge.
The advantage of rotary lobe blowers is that they create a high volume of air. In addition, they are durable, allowing them to withstand harsh environments. They are normally designed for continuous operation and also require little maintenance. On the downside, however, they have limited pressure (15 psi). They can also be less energy-efficient than other options because they allow some air to slip back between the lobes.
2. Centrifugal Blowers
Centrifugal blowers, as the name suggest, uses centrifugal force to create air flow. The air enters via a rotating impeller. The air then goes through different vanes or paddles, which forces the air to the outlet. This process of air passing through the system causes negative pressure at the rotating impeller, allowing more air to enter.
Centrifugal blowers are generally used for higher volumes at lower pressures that Rotary Lobe blowers. In clean air environments they require little maintenance.
3. Regenerative Blowers
Regenerative blowers use a spinning impeller with impeller blades. As the impeller spins and the impeller blades pass the inlet, they suck in air. As the blades continue to spin, they then push the air out via the discharge air, and the cycle continues until the impeller stops.
Regenerative blowers have a few advantages over other options. For starters, they are nearly maintenance-free. However, they will need servicing after about 40,000 hours of operation.
Normally regenerative blowers are used for low flow and low pressure, under 10 psig, applications. Regenerative blowers are commonly for dust and smoke removal, dryers, and vacuum packaging.
4. Rotary Screw Blowers
Rotary screw blowers have two, screw-like rotors. As the air
comes in via the inlet valve, it goes between those rotors, and the rotation
reduces the volume of air, which increase pressure. Rotary screw blowers are
incredibly durable because they often run nonstop without breaking.
The two options for rotary screw blowers are oil-flooded or oil-free. Oil-flooded systems contain oil in the compressor changer. This oil helps seal the air from backflowing within the blower while also serving as a coolant. Oil-free systems do not contain oil, which allows them to get hotter faster, which can affect efficiency. Plus, without oil, the system creates less pressure.
Rotary Screw blowers can handle higher pressures that the other types however because of the tighter clearances they are subject to increased wear in environments with dirty air flowing through the blower.
Every type of blower is different with different pros and cons, but as a business owner, you need to understand the machines your business needs so you can buy the right machine the first time, which can save a lot of time and money.
