Designed specifically for Airport Ground Service Equipment (GSE), the PCA series of air conditioning and ventilation hoses provides an efficient and reliable ducting solution for aircraft cabin air conditioning pre-cooling, ground air supply (PCA - Pre-Conditioned Air) and airport facility ventilation. The hose is made of high-strength composite materials (e.g. weather-resistant PVC, flame-retardant polyurethane or aluminum alloy reinforcement) and is UV-resistant, resistant to extreme temperatures (from -40°C to +120°C), and grease-resistant to ensure long-lasting and stable operation in busy airport environments.
