Regenerative Blower: A Complete Selection Guide

Are you searching for an appropriate solution to pass out large air volumes at very low pressure or in a vacuum? If your answer is yes, then a regenerative blower is the solution for you. With the advancement in technology, a modern, compact and versatile machine has been developed that can pass a large air volume at low pressure. These differ greatly from other positive-displacement compressors and vacuum pumps. They recreate air molecules through non-positive displacement to generate an accurate vacuum.

Types of Regenerative Blowers:

Regenerative blowers are of two types, they are- Single Stage Regenerative Blowers and 2-Stage Regenerative Blowers. They both vary from each other based on their performance range.

Performance Range:

  • Single Stage Regenerative BlowersThis type of regenerative blowers have a pressure range of 1 – 5 PSIG from 200 – 700 CFM. Pressure ranges up to 4 PSIG under 100 CFM.
  • 2-Stage Regenerative BlowersThis type of regenerative blowers have a pressure range of 4 – 8 PSIG from 100 – 700 CFM range. Pressure ranges up to 3 – 6 PSIG under 100 CFM.

Regenerative Blowers – Merits

  • These blowers have a lower installation rate compared to other available blowers.
  • Even they require the least maintenance. This means you can save thousands in the long run.
  • The initial investment cost of these blowers is less compared to other blowers.
  • The noise levels of these blowers are low.
  • Under the usual operating conditions, these blowers are too reliable to use.

Regenerative Blowers – Demerits

  • Under high pressure, the mechanical efficiencies of these blowers may be much lower than compared to other types of blowers.
  • These blowers are not usually made up of special material so they can not bear harsh/corrosive environments.
  • These blowers may not be suitable for areas where water and other particulates can be ingested.

How to Choose an Appropriate Blower for the Heater Applications?

Regenerative Blowers are highly transportable and are just perfect to utilize with numerous other Tutco SureHeat Air Heaters. The setup of these blowers on the equipment is too easy and can generate inexpensive, oil-free, clean air. A blower must be capable of providing your desirable airflow amount, even if there are any restrictions. Having a restriction can decrease the airflow amount to the process. These can overheat your blower and thus lead to damage. Choosing an appropriate blower is not tough if you follow the following steps.

1. Consider the Heater Back Pressure

Before choosing an appropriate regenerative blower, it is always better to consider the heater back pressure. You can find the heater’s back pressure amount at the operating instructions. At the instruction box, check out the dotted lines present at the Heater Performance Curve. The back pressure amount in PSI depends on the airflow and Heater Operating Temperature, i.e., SCFH (Standard Cubic Feet per Hour).

2. Look For The Blower Ability

The manufacturers of the blowers offer different performance curves for different blower sizes. The best outcome depends on the zero pressure of the blowers (Zero Exit Restrictions). For example, you find a blower having 27 CFM. Look at the decreased blower outcome (CFM) with the increased back pressure of the blower (Inches of water). Don’t overlook the blower outcome; it is low at the operation of 50 Hz.

To sum it up, this is all about regeneration blowers. Hope now you have gained some idea about these blowers. So, the next time when you are planning to purchase for yourself, keep these factors in mind to choose the best regenerative blowers to get the best output.
