Prem-i-air 1.5m Insulated Exhaust Hose Sleeve - for Portable Air Conditioners - EH5940

The Premiair EH5940 Insulated Exhaust Hose Sleeve is a practical accessory designed to enhance the efficiency and performance of portable air conditioning systems. Specifically engineered to fit over standard AC exhaust hoses, this insulated sleeve works by reducing heat transfer from the hot exhaust duct back into the room. By keeping the expelled hot air contained within the hose, it helps maintain a cooler indoor environment and allows the air conditioner to operate more effectively.

Constructed using insulating materials, the sleeve creates a thermal barrier around the exhaust duct, significantly limiting heat loss and improving overall cooling efficiency. This can help reduce the workload on the air conditioning unit, potentially lowering energy consumption and improving temperature stability—particularly in smaller rooms, caravans, or enclosed spaces where heat build-up from the hose can be more noticeable. Similar insulation systems are widely used to “reduce heat transfer… and improve efficiency” in air ducting applications.

Designed for convenience, the EH5940 is simple to install, wrapping securely around the exhaust hose without the need for specialist tools. Its flexible construction allows it to conform to bends and curves in the ducting while maintaining a snug fit. In addition to thermal insulation, the sleeve also provides a layer of protection for the hose itself, helping to reduce wear from heat exposure, sunlight, dust, and general use—extending the lifespan of the ducting over time.
