Every UNDERHOOD™ air compressor comes with a control box that helps the system communicate with the operator. While most operators are familiar with the very basic controls—“on” and “off”—there are dozens of unique messages the control boxes can share with you.
Pressure relief valves, or safety valves, are a simple but critical part in any air compressor system. Pressure relief valves are used to control and limit the pressure build-up in a system. If pressure exceeds the amount allowed by the pressure relief valve, the pressure relief valve will automatically open and release air until the […]
Temperature Sensors and Switches Temperature switches and sensors are used on applications which require a solution to a temperature control situation. Often less complicated than most electronic controls, temperature sensors and switches are relatively easy to set up. Temperature sensors are often used for monitoring compressor coolant, oil and air inlet temperatures as well as […]
Today many industrial engines come equipped, or can be ordered with, an auxiliary port (pump drive) that is used to power accessory equipment. Quite often you will find a hydraulic pump or a standard piston type air compressor mounted there; what isn’t seen much is a rotary screw compressor mounted there. We’ve had many inquiries […]
We’re often asked if a particular air compressor installation requires the use of an air receiver tank. Most applications will benefit from the use of air storage whether it’s a vertical or horizontal air tank. The choice of what style of tank is generally made by the installation location and the amount and type of […]
You’ve decided that a rotary screw compressor system is the right choice for your application; maybe you are converting from using reciprocating compressors. When installing your new compressor you’ll need to locate a few different components and plumb hosing between them. In this article, we’ll briefly explain the functions of the components of a rotary […]
The Buck (moisture) Stops Here! Like all compressed air drying systems, each design has its abilities and its limitations.
Heaterless Type (Pressure Swing Dryers) Dual tower desiccant air dryers are used to produce dewpoint temperatures below the freezing point of water, as well as reduce the moisture content of compressed air used in critical process applications. Typical dewpoints produced by these types of dryers are -40° F to -100° F, although lower dewpoints are […]
Protect your engine, turn off your fuel You just finished a job using your gas drive air compressor and you’re getting ready to drive to your next job. Did you remember to shut off your fuel valve? In this article we’ll explain why you should. Most small gas engines have a fuel valve that should […]
The Deliquescent type compressed air drying system is a portable compressed air drying package used mainly for media blasting and painting contractors who are doing metal surface preparation work.
