What is a regenerative blower?
A regenerative blower, or a side channel blower, is a high-pressure fan that repeatedly spins and recirculates air inside itself to create a stronger flow and pressure. They are commonly used for operations like vacuum systems, aeration, pneumatic conveying, and wastewater treatment.
How does a regenerative blower work?
Regenerative blowers operate using a spinning wheel, or impeller, which pulls air in as it spins. As the air moves inside the blower continuously, it gains pressure and speed. The blower then pushes the air out at a higher pressure from before.
Can regenerative blowers run continuously?
Most regenerative blowers can run continuously if properly sized and operated.
What materials are regenerative blowers made from?
Nearly every blower is made from aluminum, while some larger models use cast iron. For specialized applications, stainless steel options are also available.
What’s the advantage of using regenerative blowers vs other technologies?
A significant advantage to regenerative blowers is their simplicity. Not much can go wrong with them, as they operate using few moving parts and require little to no maintenance. A regenerative blower is a good choice when you need a steady, reliable stream of air in pressure or vacuum with no maintenance.
What accessories should I purchase with a regenerative blower?
FPZ offers a full line of blower accessories. The most commonly accessories are a filter, safety valve, check valve, and motor controls. Additional accessories, like silencers, sound enclosures, and vibration isolators, can make the blower quieter and easier to operate. Our special products team can provide customized solutions to meet customer needs.
How do I keep a regenerative blower from overheating?
Keep your blower properly ventilated, clean the inlet filter regularly, and operate it within its recommended pressure or vacuum range. Avoid restricted airflow and excessive loads, which can cause the blower to overheat.
How do I choose the right regenerative blower?
You can start by determining whether you need pressure or vacuum, then consider the required airflow, pressure or vacuum level, operating conditions, and available power supply. Contact FPZ to discuss your specific application and learn more about our customized solutions.
How long can regenerative blowers last?
Service life is heavily dependent on the blower’s specific application. Three to ten years is a broad estimate for a regenerative blower’s service life.
What is a regenerative blower used for?
Regenerative blowers are commonly used for operations that require continuous airflow or vacuum, such as aeration, material handling, packaging, and vacuum lifting.
Why would I use a regenerative blower?
In general if pneumatic requirements fall in the range of a regenerative blower, it is the technology of choice due to simplicity, cost, and lack of maintenance.
