While airliners have long made major efforts in ensuring the cleanliness and safety of aircraft cabin air, an increased concern in recent years has made many passengers interested in the practices conducted by various airliners to keep them safe. Many airlines have let their customers be aware of increased efforts for cleaning to prevent the spread of pathogens and viruses, as well as have discussed the presence of HEPA filters in many aircraft. HEPA filters have long seen widespread implementation in aircraft of all types since the 1990s, though it was not until fairly recently that a majority of customers became aware of such technology. As a robust equipment piece that is highly efficient at filtering air, it can be very useful to understand the capabilities and design of HEPA filters.

Like any machinery, forklifts are subject to wear and tear over time. There are many important parts of a forklift that must be regularly maintained and eventually replaced. Neglecting these parts can cause serious problems and ultimately lead to the failure of your forklift. In this blog, we will discuss the most important forklift replacement parts.

Whether one is involved in vehicle recovery, aviation, marine applications, or even theater, winches are an extremely useful mechanical device for pull in or let out objects. In their most basic form, a winch may be a spool and a hand crank, permitting operators to control the tension of a wire rope or winch cable. If there is a need for stopping the winch with force, a solenoid brake or similar device may be implemented. While seemingly simplistic in their construction and operation, winches prove highly beneficial for the means of loading, unloading, or transferring objects as needed. Depending on the application that a winch is used, the operation and assembly of the device may vary.

Most people are familiar with what a hose does, how it looks like and what it does. Generally a hose is a flexible hollow tube that is manufactured to transfer a liquid from one area to another area. Hoses may sometimes be referred to as a pipe, as that term describes a hard straight tube. However the real distinctions between a hose and a pipe is that the former is generally more flexible and the shape of it is often like a circular cross or more circular. Here at AOG Purchasing, we carry many different types of hoses and hose parts. If you’d like to learn a little more about hoses, read the article below.

Fasteners are a crucial component of construction, allowing for a variety of parts to be affixed together through mechanical means. Through permanent or non-permanent installation, fasteners can help distribute loads, establish primary connections for structural areas, and more. Carriage bolts are a widely used type of fastener, providing for various applications with their design and capabilities. In this blog, we will discuss the various common types of carriage bolts, helping you better understand their use and benefits.

Respiratory Protective Equipment, RPE, is a term that has been cropping up a lot lately which isn’t at all surprising due to the nature of the current global climate. In the changing tide of things, the team here at ASAP Semiconductor adapts to an altered world, which is why we are proud to be able to offer respiratory protective equipment now to our customers. For more information on respiratory protective equipment, read the article below.

It's incredible to think about all the ways air has been used by mankind. The importance of aircraft engine air/fuel mixture aside, another beneficial way air is utilized in the aerospace industry is through air compressed hydraulic systems. In this article, we will discuss a small yet key component of aircraft hydraulic systems, hydraulic fittings, and go over various types and uses or ways these fittings are applied. 

When a GPS system’s service is interrupted, an aircraft’s Inertial Navigation System (INS) is there to save the day. This self-contained flight management system provides aircraft locale without the need for input radio signals from ground navigation facilities or transmitters. The location of an aircraft is continuously updated through calculations based on the forces experienced (altitude, velocity, direction, accelerations) by INS accelerometers. An interface control head is used to input a starting location and from there any movement force data recorded by an accelerometer is then used to calculate an aircraft’s location based on that starting point.  A minimum of two accelerometers are used, one referenced to the north and one referenced to the east. In older units (due to gravity), accelerometers are mounted onto a gyro-stabilized platform that averts the introduction of error. An accumulated error of less than one mile after one hour of flight is possible.
