Pneumatic Conveying
Using compressed gas (air) and/or vacuum to move bulk materials such as granules and powders is called pneumatic conveying. Whether a dilute phase, dense phase or other type of pneumatic conveying system, producers know that pneumatic conveyance is the life blood of their plant. This is why the cement industry has relied on Ro-Flo compressors and vacuum pumps as the heart of their pneumatic conveying systems for over 40 years. […]

If you’re thinking about purchasing a high pressure gas compressor from Ro-Flo for your application, you’ve likely noticed that we offer two options for the shaft seals.
Benefits Of Using A Vapor Recovery Compressor
A vapor recovery compressor is a specially designed compressor used for handling wet, heavy , or acidic gases.
Rotary Vane Compressor Health and Longevity
Rotary vane compressors are known for their ability to handle saturated and corrosive gases. Their durability in tough environments is why they are commonly chosen for vapor recovery, flare gas and various industrial process gas applications.
What are the Advantages of a Two Stage Gas Compressor?
When the discharge pressure needed for an application cannot be reached with a single stage gas compressor, a two stage gas compressor is needed. While a two stage gas compressor is more expensive, more complicated to operate, and requires additional equipment, there’s simply no other way to reach a higher discharge pressure if a single stage gas compressor isn’t cutting it.
Biogas Compressor Maintenance Schedule
RoFlo Compressors reviews the best biogas compressor maintenance schedule to help keep them in perfect condition and working order.
Rotary Vane vs. Reciprocating Compressors – Compressor Comparison
RoFlo Compressors reviews the compressor comparison between the rotary vane and reciprocating compressors.
Advantages to Using a Rotary Sliding Vane Gas Compressor
The rotary sliding vane gas compressor is a cleverly designed, yet simple machine. It consists of a rotating element (the rotor) inside of a cylindrical casing (the cylinder).
Sliding Vane Compressors and Vacuum Process Equipment
Sliding vane compressors are powerful machines. They can also be used in a wide variety of industries in vacuum pump applications.
Vegetable Chilling with Vacuum Cooling
Preserving vegetables for transport is a unique challenge the food processing industry faces. Once harvested, produce has a limited window of freshness.
Types of Gas Compressors
A compressor is a mechanical device that increases the pressure of a gas by reducing its volume or by imparting velocity on the gas. This can be done in numerous different types of gas compressors.
Sliding Vane Compressor Benefits
A sliding vane compressor is a positive displacement compressor, meaning it decreases a specific volume of a gas, resulting in increased gas pressure.
Common Rotary Equipment Tests and Analyses
Compressor testing can be utilized to validate expected performance, analyze product developments, determine baseline data in a controlled environment, troubleshoot unexpected or undesirable operation and much more.
Compressing Gas Streams Containing H2S
Sour gas is any gas containing significant amounts, typically above 20ppm, of hydrogen sulfide (H2S). H2S is a colorless gas that is heavier than air and harmful to humans at concentrations of 20 ppm in air.
Why Direct Injection Compressor Lubrication Is the Best Choice
Direct injection compressor lubrication is used in sliding vane gas compressors and has distinct benefits over other types of lubrication used by other compressors.
Common Oil and Gas Industry Applications for Gas Compressors
Despite advances in renewable power sources, crude oil remains one of the most valuable natural commodities today.
Biogas Management: What to Know About the Renewable Energy Source
Biogas is a natural energy source made from the decomposition of biological matter. More simply put, when food, animal waste, plants, sewage, and other natural waste is broken down by bacteria, a gas is formed that includes methane.
Benefits Of Using Vacuum Cooling In Food Processing
The International Trade Administration (ITA) estimates that nearly half of all food is lost before it ever reaches a consumer’s table.
