Regenair® Regenerative Blowers

Regenair regenerative blowers

Regenair regenerative blowers are a type of industrial blower that uses a unique operating principle to move air or other gases. These blowers are designed to deliver high volume, low-pressure airflow, and are commonly used in applications such as wastewater treatment, pneumatic conveying, vacuum lifting, and other industrial processes that require the movement of air or gas.

Regenair® blowers work by utilizing the regenerative principle, which involves a spinning impeller that generates a high-velocity airflow that is directed into a stationary stator. As the air passes through the stator, it is redirected back into the impeller, where it is compressed and forced out through the discharge port. This cycle of compression and expansion creates a continuous flow of air or gas.

One of the main advantages of Regenair® blowers is their efficiency. They are able to achieve high flow rates with relatively low power consumption, making them an energy-efficient option for many industrial applications. They are also compact, durable, and require minimal maintenance, making them a popular choice for a wide range of industries.

Overall, Regenair® regenerative blowers are a reliable and cost-effective solution for many industrial applications that require the movement of air or gas.

The Regenerative Principle

In a regenerative blower, the compression space consists of a hollow,
circular ring between the tips of the impeller blades and the walls of the
housing. In operation, the rotating impeller draws in air from the inlet
port into the compression space and moves it radially outward to the
curved housing by centrifugal force.
The action is called “regenerative” because a certain amount of air
slips past each impeller blade during rotation and returns to the base
of a succeeding blade for reacceleration.
Because of this dynamic principle, regenerative blowers can generate
pressure and vacuum performance comparable to many multi-stage or
positive displacement blowers.

Catalog Performance Specifications

The specifications listed are that of a unit at sea level with an ambient temperature of 70 °F (21 °C), operating with normal electrical current conditions. The figures stated in this catalog are nominal approximations for models without accessories. Intake filters and exhaust mufflers, and the accumulation of contaminants in them during operation, will decrease the flow of air as well as the achievable pressure. The units that we list in this catalog are a small portion of what we actually make. Those listed are considered “standard units” and are normally available from stock in small quantities. Variations are produced for many customers and by informing us of the application specifications we might find an existing unit that fits your requirement. If we don’t and the quantity is sufficient, we will design a “special unit” for the application. Pictorial and dimensional data is subject to change without notice.

Blower System Design Tips

In order to utilize your regenerative blower most efficiently, proper system design is essential. The most important thing to recognize is that by utilizing large diameter plumbing, friction losses in plumbing can be greatly reduced. Here are some guidelines to use when setting up your blower system:

1. The plumbing should at least be the same size as the blower port or ideally one size larger (example – blower has ports that are 1-1/2” NPT, plumbing should be 2” NPT). The plumbing should remain this size until it has reached the location of the work area.

2. Plumbing for Separate Drive Blowers operating above 3500 RPM should be at least one pipe size larger than the blower ports.

3. Elbows create additional friction, which causes pressure loss and back pressure. Plumbing at least one pipe size larger than the blower pipe ports minimizes the friction loss they create.

4. The pressure/vacuum relief valve should be installed in a “T” which is at least one pipe size larger than that of the exhaust of the blower. To properly protect a large horsepower blower, set the relief value to limit the blowers duty to 5 in H₂O below its continuous duty rating.

5. Operating the blowers at high altitude decreases their maximum pressure or vacuum duty rating. If this is a consideration, review the information on Fan Laws in the Application Engineering section of this catalog.

6. The exhaust air temperature of the blowers increases with increasing duty. At duties over 70 in H₂ it is too hot for most plastic pipe. Metal pipe must be considered. To prevent danger of burns, access to these pipes should be limited, guarded, or marked “Danger Hot.”

PRESSURE APPLICATIOS

Bag Packaging Equipment

Vacuum is often used to open,
hold, and close bags in filling machines.

Vacuum Conveying

Plastic pellets, grain, powder, and other bulk dry materials can be transported from one container to another easily using vacuum. They are pulled into a transport tube and delivered to a separator before being deposited
in the final storage container.

Pond Aeration

Pond aeration is done for two basic reasons. One is aquaculture, where large numbers of fish are “farmed” in a single pond. The second is ecological.
As a pond or lake ages, it can lose its oxygen supply and may die. When air is introduced into a pond or lake, oxygen becomes plentiful again and life in and around the water can flourish.

Paper Stack Air Table

The stacks of paper in all graphic arts applications are extremely heavy. To make matters more difficult, the combination of high speed presses and the various types of paper make it necessary to handle these stacks frequently. To make the job easier, these stacks are floated on an air table so they can be manipulated with very little effort.

VACUUM APPLICATIONS

Vacuum Holding of Automated Cutting

Lasers, water jets, and knives are all precision tools for cutting a wide variety of materials automatically. These computers driven machines use vacuum to hold materials being cut in place.

Automated Product Feeding

Vacuum force is used to automatically stack product as it is received or to move the product from one process to another.

Soil Vapor Extraction

Contaminated soil is often treated by pulling the contaminants, usually gasoline or other hydrocarbons, out of the soil with vacuum.

Dust and Chip Collection

Vacuum power is used to collect dust and/or chips from saws, mills, and other cutting machines.

Home Aerobic Sewage Treatment

Some parts of the country where city sewerage is not available and high water tables exist, household waste must be treated aerobically. This means air is mixed into a solution which activates microbes that feed on the waste, speeding up the naturally occurring organic breakdown.

Performance at 60 Hz

Gast advertises blower performance in Free Air Flow, or air subjected to only atmospheric pressure. (See above curves) Some blower manufacturers advertise vacuum performance in CFm Inlet Air – measurement of the suction of air at a specific temperature at the inlet port and a specific discharge pressure at the exhaust port, which can be perceived as enhanced performance over Free Air Flow rated blowers. Therefore, we are also providing the following vacuum performance for Gast blowers in CFm Inlet Air for comparison to other blower manufacturer’s advertising.

MPT = male Pipe Thread. FPT = Female Pipe Thread. All are heavy-duty for high amounts of particulates.
Inlet filters for REGE nAIR ® blowers are drip-proof when mounted as shown.

Filters

In locations where there are high amounts of dust, powder, or dirt suspended in the air, inline filters (for vacuum applica – tions) and inlet filters
(pressure applications), should be used. Keeping particulates from entering the blower will ensure smooth operation and trouble free service life.
