A NECESSITY FOR AIRCRAFT

The PCA system treats the air, i.e., through filtering, compressing, cooling, or heating the air, after which it is carried via the hoses and connectors into the cabin ducts, from where it flows into the cabin.Unlike other vehicles, aircraft cabins are more airtight to resist the change in pressure and other elements that can affect equipment in the cockpit . PCA hoses allow expensive and sensitive equipment to remain at a constant temperature at all times for the ground support crews. If it wasn’t for PCA hoses, planes would cost much more to maintain because of possible damages to the elaborate system of electronic instrument panels and other parts that most vehicles don’t possess. Preserving equipment conditions wouldn’t be as easy without the use of various PCA hoses available, which is why they have become a crucial part of overall aircraft maintenance measures.

Comparison - PCA Flat Hoses versus Rigid Ducts

FLAT HOSES

Unlike other PCA hoses, flat hoses are designed for more convenient storage, folding completely flat when not in use. They are ideal for personnel who require quick and efficient storage that allows more room for other hoses or equipment. Flat hoses also resist tearing while providing an entirely airtight RF welded seal, and they come in different models depending on the applications for which they’re needed. Custom lengths, diameters and end fittings are available to meet specific requirements as well.

RIGID DUCT HOSES

Although rigid duct hoses are not specifically designed for ease of storage, they are fabricated to resist tearing and kinking with divided sections. These flexible ducts contain wire pitches that allow pre-conditioned air to flow through regardless of the hose’s position. Rigid duct hoses work for aircraft maintenance that requires ample maneuverability, giving personnel the chance to work with hard-to-reach aircraft ports. Hose hanger slings are also useful, holding rigid duct hoses in place beneath a jet bridge to help further avoid kinks and restrictions.

Application Study

When choosing PCA hoses for aircraft air quality control there are multiple designs to select, each with its own advantages.

Both rigid duct and flat hoses are designed to keep insulated air in while preventing leakage or contamination, and all are made for convenience of storage. With PCA hoses, ground support crews have full control over temperature and humidity in aircraft cabins.

Different types of aircraft are likely to encounter different environmental conditions that affect the plane, which makes it important to know which PCA hoses will work best to keep the air quality consistent.

Different types of hose include vented hoses which prevent condensation from getting inside the cabin and wearing out equipment, lay flat hoses that are folded flat to allow for easier storage and use, and rigid duct hoses divided into flexible sections that avoid damaging wear and tear.
